Machine tool users are more financially sound, but business is not growing rapidly. According to a report from Agie Charmilles Corp. (Lincolnshire, IL), our economy is clearly reacting to high interest rates and oil prices. Tooling appears to be holding up better than production. If the recent weakening of the US dollar continues and the Federal Reserve does not attempt to strengthen the dollar with higher interest rates, it's likely that long-term manufacturing growth will continue.
The Charmilles Machining Business Activity Index was down moderately at 62 from 67 in May. The improvement in business activity was strongest in the Captive Production sector and was uniformly strong in all regions. For more information try

Cutting tool support for the automotive industry
The Leitz Metalworking Technology (LMT) Group has established an Automotive Support Center (ASC) for the North American automotive industry in Auburn Hills, Michigan. The ASC serves as a technology source for cutting tool development, installation, presetting, refurbishment and management.
The center is designed to support customers in production or new-tool-runoff phases. Its facility includes presetting equipment and various machine tools and grinders for tests and demonstration purposes. The ASC training center has direct access to other LMT companies and the Engineering Center located in Oberkochen, Germany, via an internal broadband computer network.
"The two most important trends we are currently observing in the automotive industry are globalization and localization," notes Dieter Brucklacher, executive chairman of the company. "Globalization is compelling businesses to build networks--not only internally, but also externally--and to form partnerships. Localization, on the other hand, means that businesses have to be in a position to support their local partners." The ASC was developed to address both of these needs.
The ASC offers a regrinding unit for tool refurbishment and modifications. Also, a separate production and service unit has been setup at Onsrud, the North American LMT production company. Onsrud is now producing solid carbide tools for the automotive industry, in addition to tooling for composite materials and hobs

Integrated tool management solution—DLoG
WinTool is a software solution developed to address costs associated with tool logistics and planning, including indirect costs arising from factors such as chaotic tool storage and purchasing conditions, errors in presetting or the use of mediocre cutting data. The software integrates all CAM tool data, as well as presetting gage storage, ERP-system and production data management into a central database. This eliminates "paper traffic" and isolated data tables in different departments, enabling simple tool communication and reduced errors.
Using the software, companies can develop a tool library with complete information about tool components, assemblies and lists, as well as information on 2D/3D geometries, technologies, CNC operations, stock, suppliers and manufacturers. In addition, the company says the software is in sync with industry norms and the latest developments of common CAD/CAM systems, which can help alleviate interface costs caused by integrating with third-party solutions.
To optimize manufacturing for a new NC program, the software accesses detailed tool data--including cutting data from previous jobs--directly out of the CAM system. It then compiles a list of the finished NC program and verifies the availability of all used components. Finally, the program generates 3D tool solids In the shop, operators must calculate a "tool net list" before presetting the job for a machine. Depending on the work, the tool list can be in any format. For example, formats could include a parts list with bar codes for gathering components, a setup sheet for production or a measured tool drawing for presetting. The company says this can increase efficiency by ruling out possible mistakes early in the process and reduce machine downtime caused by tooling issues. In addition, companies will have access to information about quality, operation time and lifetime for future jobs. They also and will be able to analyze and optimize tool usage and waste.
Manufacturers also can use this solution to quantify tool needs directly out of the NC program. In addition, a central "shopping cart" replaces purchase order request forms in all departments, which can simplify coordination. Operators can transmit evaluated demand directly to the ERP system and integrate tool dispensers from suppliers with the software. This is said to allow reduction of tool variety and stock level in the shop and help eliminate administrative overhead.

Conceptual design of machine tool interfaces for high-speed machining
High-speed machining is a promising technology to drastically increase productivity and product quality. However, conventional machine tool design often cannot meet stringent requirements needed to overcome various problems brought about by high-speed rotations. One particularly critical issue is how to hold an exchangeable tool rigidly during high-speed rotations. For this purpose, several new standards of tool interfaces between the toolholder and the spindle nose have been proposed. However, it has become increasingly difficult to choose among various competing interface standards or even different variations within a common standard. This issue is further complicated because many machine tool builders also offer various proprietary modifications to the common standards. Furthermore, there is also a need to develop new tool interfaces or modifications if existing standards are not satisfactory. The objective of this paper is to provide a systematic approach that can assist in the conceptual design of machine tool interfaces for high-- speed machining. This conceptual design methodology can also be used to select appropriate interface designs from various competing alternatives that exist today. Two embodiment concepts for high-speed end milling are developed as a case study based on the proposed conceptual design methodology. It is shown that the proposed design methodology can assist systematic design decision making and sound reasoning of the design choice.Machine tools such as machining centers have spindles that consist of the arbor, the toolholder, and the tool, with interfaces and separation points in between (Ronde 1991). Toolholding is essential for machining processes to establish precise relative positions between tools and workpieces (Agapiou, Rivin, Xie 1995; Aronson 1994a, 1994b). As machining speed and precision requirements become higher, the need to hold tools rigidly at high speeds and under high loads continues to grow in importance. Tool interfaces are pairs of mating geometries that are standardized to permit exchangeability. This paper deals with the interface between the toolholder and the spindle nose. In general, the interface includes three major couplings: the mating surfaces of (1) the toolholder and the arbor, (2) the toolholder and the tool, and (3) the gripping chuck and connections to the toolholder, which are used for tool ejection and optional transmission of cutting fluid. Figure 1 illustrates the location of the interface of interest and the related components.
7/24 Taper Shank
Conical shanks without keys were the earliest shapes of tool interfaces. The basic principle is a conical toolholder that is drawn into an equally shaped hollow cone with a constant force that is usually generated by spring or hydraulic pressure. The conical surface centers the tool, determines its axial position, takes all external forces and bending moments, and transmits torque. To transmit torque, it is important that friction between interface surfaces is sufficient during operation.
One radius-to-length ratio of the cone was chosen as 7/24, which became a standard both nationally (ANSI B5.18-1960, ANSI B5.18-1972) and internationally (ISO 7388). For automated tool change, a circular groove with a V-shaped cross section was added, which is known as a V-flange tool shank (ANSI B5.50-1978). The 7/24 steep angle taper is the most common interface type for machine tools with large inventories in industry (Beier 1994, Wang and Horng 1994, Weck and Schubert 1994).
Various gripping mechanisms are available for the 7/24 toolholder. Most often, a retention knob is added at the tail of the taper, where it can be clamped by levers from the outside and drawn axially into the spindle nose. Another common option is a threaded bolt built in as part of the spindle that can be activated to screw or unscrew the toolholder (Effenberger 1987).
Many problems, however, are associated with 7/24 toolholder interfaces. One problem is that tool-- holders from different companies are not always exchangeable because this toolholder standard leaves too many aspects unspecified (Eckle 1986), and many companies have developed their own proprietary modifications.
Another problem with the 7/24 steep angle taper is its comparatively lower radial stiffness for the same nose diameter (Scheer 1986). The standard 7/24 taper is defined to guarantee a clearance between the end face of the spindle and the tool-- holder flange. The lack of end surface contact can result in lower radial stiffness. This problem can be explained by a stiffness cone concept as shown in Figure 2. An imaginary cone can be drawn, with the cone base defined by the most outward contact points. The length of the stiffness cone provides a comparison for permissible external radial loads without exceeding a given deflection. The angle of the imaginary stiffness cone can be chosen arbitrarily but must be held constant for comparison of alternatives. As shown in Figure 2, for two conical shanks of the same diameter, the one with a flange (Figure 2b) has a longer stiffness cone and thus suggests a higher radial stiffness than the one without (Figure 2a). Of course, proper end-surface contact with the flange is assumed for this comparison. However, it is not a trivial issue to achieve proper end-surface contact. The precision requirement for the relative positioning between the taper and the end surface is very high. This issue is critical and must be addressed.

Speed increasers improve machine productivity - Modern Equipment Review - Brief Article - Product Announcement
The company announces the availability of a new series of high speed spindle increasers that is said to offer greater rigidity and accuracy. The Big-Sheppard GTGhigh speed spindle increasers make it possible, even on low speed machines, to run cutting tools at higher speeds in order to obtain optimum tool performance and a reduction in machine time usage. Further, since the cutting resistance of the tool tip decreases as the cutting speed increases, the possibility of tool breakage is greatly reduced. In addition, by lowering the operating speed of the machine, heat generation and hearing wear will be minimized, thereby prolonging the life of the expensive machine spindle.
The increasers are equipped with hardened and ground steel gears that minimize noise and vibration. Super precision high thrust angular hearings along with rigid and large diameter spindles permit high speed and feed carbide operations.
Models for machining centers feature a coolant jacket and multi-directional coolant nozzles that efficiently direct the coolant to the tool cutting edge while simultaneously cooling the body. The compact design with adjustable locating pin assemblies and 360-degree adjustable orientation rings assure smooth operation in the automatic toolchangers of machining centers. Models for conventional machines use a stop bar to prevent rotation and are available with NMTB tapers as well as straight shankshe increasers are available in four different ranges. The Model GTG6 has a collet capacity of 3/8" and will increase speeds up to 20,000 rpm with a 6 to 1 increasing ratio. The Model GTG5 has a collet capacity of 3/8" and will increase speeds up to 20,000 rpm with a 5 to 1 increasing ratio. The Model GTG4 has a collet capacity of 5/8" and will increase speeds up to 15,000 rpm with a 4 to 1 increasing ratio. All of these models are equipped with the company's precision New Baby chuck collet system that offers high accuracy. The heavy duty Model NXG3 has a collet capacity of 1 1/4" and will increase speeds up to 8,000 rpm with a 3 to 1 increasing ratio

CNC Vertical Hobbing Machine optimizes dry machining
Based on single-piece frame cast from polymer composite material, Genesis(TM) 130H can be installed and re-located with no special lifting equipment. Direct-drive spindle motors eliminate need for mechanical adjustments, while cam-driven double gripper loader enables part load/unload times of 2 sec. Work area is isolated from machine frame to minimize thermal expansion from contact with hot chips. Stainless steel cutting chamber with steep inclination ensures that chips fall clear of work area.
********************
Rochester, New York, February 16, 2006-- Gleason's new Genesis(TM) 130H CNC Vertical Hobbing Machine features a revolutionary new design that optimizes dry machining, significantly reduces floor space requirements and greatly improves cycle times.
The 130H Hobber is the first in a new family of gear production equipment from Gleason called Genesis(TM). All of the Genesis machines share a common platform: a single-piece frame cast from an advanced polymer composite material, which can be made faster, more accurately and with inherently more rigidity than conventional cast-iron assemblies. This common platform design also ensures a small, compact machine footprint and enables the user to install and re-locate the machine with no special lifting equipment or special foundations While the 130H Hobber can accommodate wet cutting processes, it is particularly well-suited for dry machining. The work area is completely isolated from the machine frame to minimize thermal expansion from contact with hot chips, and a stainless steel cutting chamber with steep inclination ensures that chips fall completely clear of the work area.
The 130H Hobber is equipped with an innovative new mechanical cam-driven double gripper loader fully integrated into the machine. As a result, costly non-productive time can be cut to a minimum, with part load/unload times as short as two seconds.
Unlike conventional hobbing machines, the Genesis 130H utilizes a new, patent-pending hob drive system to eliminate complicated mechanical and hydraulic clamping systems. Instead a simple "D-Drive" system enables the spindle to transmit more torque, with less runout, and at the same time accommodate the use of larger diameter hobs for greater performance and longer tool life.
The 130H also features direct-drive spindle motors, which further reduces setup and machining times by eliminating the need for mechanical adjustments and change gears. Higher acceleration/deceleration rates and increased torque, combined with faster axis motions reduce non-cutting time between cycles and increase overall productivity during machining.
Other significant features include:
o An Easy Access Service Module that consolidates hydraulics, lubrication and pneumatics into one location.
o Optional on-board chamfering and deburring capability.
o Availability of the latest SIEMENS or FANUC controls and the latest Gleason software running in a true Windows[R] environment.
o The chip conveyor may be located from either the side or rear of the machine to meet any cell/system arrangement.

Today's bar essentials: as the art of the cocktail becomes more sophisticated, the bar tool box gets an update
You can make a drink, or you can craft an experience," says Tony Abou-Ganim, the prominent beverage consultant also known as The Modern Mixologist. "But to craft an experience, you need the proper tools."
While professional chefs have "tool" kits--good knives, favorite tongs, brushes, and more, says Abou-Ganim, "a lot of bartenders are used to using whatever tools are available to them at the bar." To remedy that, Abou-Ganim recently began marketing his TAG Bar Tools line to provide today's bartenders with a tool kit similar in quality to those of top chefs.
[ILLUSTRATION OMITTED]
"But times are changing," adds Ryan Magarian, professional mixologist behind Liquid Kitchen beverage consulting in Seattle. "Chains are beginning to understand that the bar should be an intrinsic part of the concept's overall culinary experience." And as the culture for cocktail excellence grows, beverage professionals are becoming much more savvy and choosy about the tools they use to enhance both the beverage and bar experience.
So, what's the well dressed bar wearing? "First and foremost, a good quality Boston shaker," says Kathy Casey of Kathy Casey Food Studios in Seattle. Boston shakers, which consist of a pint glass and tin, have advantages over the three-piece, solid metal shakers with the built-in strainers and jigger tops, according to Casey. "The three-piece shakers tend to stick and when you do get them apart, it's abrupt and you spill," she says Adam Seger, noted bar chef and general manager of Nacional 27, in Chicago, agrees. "I like a really heavy-duty glass pint and tin, and I actually like a pint that's marked with ounces."
BUY QUALITY
Magarian gets even more specific. "The best tin I've found is the Vollrath 30-ounce. It forms a tight seal, but pops apart from any standard pint easily every time." Magarian adds that shakers that stick and spill can ruin a bartender's confidence--he or she might avoid using them as a result. Abou-Ganim agrees, "Do not spend $1.99 on a tin; it's like a chef buying knives at the discount store."
Next up, muddlers. Until recently, muddlers hadn't changed much in 20 years--they were still dyed, lacquered, too short, too narrow and made of soft wood, writes Dave Nepove on his web site, www.mistermojito.com. "Varnish and dyes are no-no's," says Abou-Ganim, whose TAG line includes a hardwood muddler. "After a while they chip, and where do you think those little flakes go?"
[ILLUSTRATION OMITTED]
[ILLUSTRATION OMITTED]
Nepove's line of Mr. Mojito muddlers also addresses those issues head-on. "We use the hard plastic version of Mr. Mojito at the Cheesecake Factory," says Matt Raftree, beverage and bakery operations manager for the 100-plus-unit Calabasas Hills, Calif.-based chain. "Other muddlers were always too short; if you tried to muddle in the tin you'd cut your hand. We made our bartenders very happy when we brought in the new muddlers."
The Mr. Mojito muddler is 10-inches long and bat shaped; the Mr. Mojito Master muddler is 12 inches with a wide bottom on one end that tapers to a narrower diameter on the other end. Both ends can be used for muddling fruit, herbs and more.
The plastic versions are dishwasher safe. Magarian likes them because they will never pick up flavors of the items being muddled; others prefer the hardwood versions, citing the notion that muddlers can become "seasoned."
Another muddler gaining fans among top mixologists, including cocktailian Gary Regan, is the Pug!, a fat-bottomed muddler with a tapered handle handcrafted by woodworker Chris Gallagher of Cornwall-on-Hudson, N.Y. Word-of-mouth raves are driving sales, and Gallagher may soon take orders via the web.
STANDARD STRAINERS
After all that shaking, stirring and muddling, you need to separate the potables from particulates. The standard strainer is the Hawthorne, with two or four prongs and a wire spring around the edge. It fits into the tin or pint to strain the beverage. Less common, but coming on, is the Julep strainer, a perforated, spoon-shaped strainer that is held over the serving glass to strain larger bits of fruit, herbs, pulp, rind and such.
"The general rule is: If a drink calls for a spirit with juice, milk or cream, shake it with the ice and strain it with a Hawthorne because you are looking for the froth; you want some texture," explains Abou-Ganim. "If the drink calls only for the base spirit and flavoring ingredients--a Negroni or Manhattan--use a long-handled bar spoon to stir it with ice and pour it smoothly into the serving glass, using a Julep strainer. This results in a clear, elegant cocktail."
The latest addition to the strainer family is a kitchen sieve or fine mesh skimmer--the kind chefs use to clarify bouillon, for example. "We started using three-inch diameter mini strainers for our fresh strawberry-infused drinks," says Cheesecake Factory's Raftree. "They're very fine and really strain out all the particles and seeds

The Mr. Mojito muddler is 10-inches long and bat shaped; the Mr. Mojito Master muddler is 12 inches with a wide bottom on one end that tapers to a narrower diameter on the other end. Both ends can be used for muddling fruit, herbs and more.
The plastic versions are dishwasher safe. Magarian likes them because they will never pick up flavors of the items being muddled; others prefer the hardwood versions, citing the notion that muddlers can become "seasoned."
Another muddler gaining fans among top mixologists, including cocktailian Gary Regan, is the Pug!, a fat-bottomed muddler with a tapered handle handcrafted by woodworker Chris Gallagher of Cornwall-on-Hudson, N.Y. Word-of-mouth raves are driving sales, and Gallagher may soon take orders via the web.
STANDARD STRAINERS
After all that shaking, stirring and muddling, you need to separate the potables from particulates. The standard strainer is the Hawthorne, with two or four prongs and a wire spring around the edge. It fits into the tin or pint to strain the beverage. Less common, but coming on, is the Julep strainer, a perforated, spoon-shaped strainer that is held over the serving glass to strain larger bits of fruit, herbs, pulp, rind and such.
"The general rule is: If a drink calls for a spirit with juice, milk or cream, shake it with the ice and strain it with a Hawthorne because you are looking for the froth; you want some texture," explains Abou-Ganim. "If the drink calls only for the base spirit and flavoring ingredients--a Negroni or Manhattan--use a long-handled bar spoon to stir it with ice and pour it smoothly into the serving glass, using a Julep strainer. This results in a clear, elegant cocktail."
The latest addition to the strainer family is a kitchen sieve or fine mesh skimmer--the kind chefs use to clarify bouillon, for example. "We started using three-inch diameter mini strainers for our fresh strawberry-infused drinks," says Cheesecake Factory's Raftree. "They're very fine and really strain out all the particles and seeds
Turning Center has tool setter with4-position touch sensor
Offered in 3 models with 6.5 or 8.25 in. chuck, Lynx 220 OD Turning Center is powered by 20 hp motor and features 30[degrees] slant bed with single-piece, strategically ribbed design and fine-grain Meehanite composition that dampens vibration and helps dissipate heat. Spindle accelerates to 6,000 rpm in 2.3 sec, and rapid traverses for X and Z axes are 1,181 and 1,417, respectively. Heavy-duty, 12-station turret is non-stop and bi-directional with 0.15 sec station index time.
********************
West Caldwell, NJ - The new Lynx 220 packs speed and power in an economical O.D. turning center.
Three models are available: the 220A with a 6.5" chuck, the 220C with an 8.25" chuck and a 220LC with an 8.25" chuck and elongated bed. All are powered by a 20 Hp motor that provides the muscle to power through heavy cuts in tough metals.
A 30[degrees] slant bed maintains a minimal and constant distance from tool tip to guideway, and assures maximum rigidity and eliminates of deformation under heavy loads. This design also allows excellent chip flow and operator access for loading and unloading material, replacing chucks and tools, and repositioning the optional tailstock. The one-piece bed is strategically ribbed. Its fine-grain Meehanite composition dampens vibration and helps dissipate heat. The spindle accelerates to its peak 6,000 rpm (Lynx 220A) in a quick 2.3 seconds. The large contact surface of the cylindrical roller bearings provides high rigidity for heavy loads and mirror finishes. All bearings are permanently lubricated, precision class P4.
The 12 station, heavy-duty turret is non-stop and bi-directional, with a quick 0.15 sec. station index time. Its heavy-duty design, with a large 8.27" diameter curvic coupling, provides high rigidity, long boring bar overhang ratios, and extended tool life. Rapid traverses are 1,181 ipm on the X axis, and 1,417 ipm on the Z. An integral tool setter minimizes the need for manual skim cuts. Its four-position touch sensor allows tool setting in any direction. Offsets are entered automatically in the controller, eliminating errors that can arise from manual data entry.
Automatic forced lubrication is provided to all guideways, ball screws and the tailstock quill. Non-clogging piston distributors minimize way lube consumption. The 1/2 gallon lubricant reservoir lasts up to 100 hours. Sensors activate a low-level alarm, and monitor pressure to detect open or broken lube lines.
Coolant is delivered through the turret from a 30 gallon tank by a 1.2 Hp multistage centrifugal pump. The 65 psi of pressure flushes chips from drilled holes, often eliminating the need for time-consuming peck and drill cycles. The coolant tank and chip pan are separate from the machine bed, preventing heat transfer to the machine casting. A waylube separation system removes tramp oils from the coolant reservoir, and deposits it in a separate external tank
