Machine tool basics: Part 2
This second installment of our series looks at key machine-tool elements and addresses the tool, the toolholder, and machine control.
The cutting action in a machine tool when milling and drilling involves the spindle, toolholder, and tools.
Spindle Design
Spindles, which secure the tool and its holder, are key in determining machine tool accuracy. In early machine tools, the spindles were simple bearing-- mounted shafts driven by a constant-speed electric motor, achieving different speeds through belts and gears. Operators changed spindle speed by shifting gears or moving belts to and from various pulleys.
As drive motors achieved higher torque and were designed to operate at variable speeds, belt and gear-driven systems began to wane in popularity, but both are still used. Stronger, longer-wearing, quieter belt and gear-- drive designs have been developed. Variable-speed direct drive, or integral-- motor spindles have replaced geared spindles for high-speed applications. At the same time, spindles with planetary gear systems, much like a car's automatic transmission, are now used to provide a wide torque output.This second installment of our series looks at key machine-tool elements and addresses the tool, the toolholder, and machine control.

Ultra high-precision technology will dramatically improve machining of new
materials used in today's aircraft
Hebron, Kentucky, December 20, 2005 - Cincinnati Machine announced today that it has expanded its HyperMach(TM) Series of High Rail Linear Motor Profilers by adding a Drilling and Trimming Router platform. This new machine will serve to meet today's demand for extreme accuracy in high-speed processing of composites. The design is also well-suited for a variety of other new materials, metallic & non-metallic honeycomb and aluminum as well as structures utilizing a combination of these materials.
As the use of new, high-strength/light-weight materials has migrated from military to commercial aircraft, improved drilling and trimming capabilities are required to meet higher volume assembly rates, according to Cincinnati Machine engineers. Less sophisticated routers designed for wood or plastic materials can no longer provide the accuracy or throughput required for determinate assembly processes used to produce today's commercial and military aircraftCurrently, Cincinnati Machine offers two HyperMach platforms. A single 5-Axis head plate mill delivers a 460 cubic in./min. metal removal rate for aggressive cutting of large aluminum structures. The Twin Independent 5-Axis Head, Dual Work Zone Machining System offers the same powerful cutting capability with the added flexibility of large capacity automatic toolchangers. This configuration provides extremely high spindle
utilization facilitated by the ability to load/unload parts in one work zone while machining two parts simultaneously in the second work zone.
The new Router platform incorporates proven Hyper Mach machine modules that include expandable X-Axis travel available in rack & pinion or linear motor direct drive configurations, standard linear direct drive Y-Axis, and vertical ram and A/C spindle head. Additionally, the HyperMach Router is equipped with a fully integrated internal chip and dust vacuum system to accommodate dry or near-dry machining.
The new router will be offered with multi-function options to maximize flexibility in meeting a wide variety of processing approaches. The first HyperMach Drill and Trim Router will be available for delivery in late 2006. Complete information on the HyperMach Drilling & Trimming Router platform can be obtained by contacting Cincinnati Machine toll-free at 1-800-934-0735, or by visiting the company's web site at www.cincinnatilamb.com

Smarten up your cardio: which machine blasts the most calories? How hard do you need to exercise? We've got the answers, plus three workouts to help y
You know that cardio workouts are crucial for a healthy heart and lungs and that they burn calories and fat, lower stress and boost energy. But what are the factors that make for the best possible sweat session? Is one machine better than another? How hard should you push yourself? Do you need to do more cardio, or less?
With so much confusion, it's no wonder a lot of us simply climb on our favorite machine (or the one we loathe the least), press the same old buttons and sink into a comfortable routine, inevitably undercutting our results. To the rescue: this exclusive Smart Cardio plan, designed to help you get the most from your workouts.
Created by certified trainer Keli Roberts, group fitness manager at Equinox in Pasadena, Calif., and a competitive cyclist, these mega-effective programs each focus on a specific goal. We'll show you which type of aerobic training is best for losing weight, boosting endurance and staying motivated. If you still have questions about all things cardio, turn the page for enlightening answersfitness experts weigh in on seven common conundrums.
q How much cardio do I really need?
a It depends on your goals, says Glenn Gaesser, Ph.D., an exercise physiologist at the University of Virginia in Charlottesville. For weight loss, at least 200 minutes of moderate-intensity cardio a week may be optimal, he says. In one recent study published in the Journal of the American Medical Association, obese women on calorie-controlled diets who exercised at least 200 minutes each week lost nearly 14 percent of their total body weight, while those who accumulated fewer than 150 minutes of exercise reduced their weight by less than 5 percent. "When it comes to shedding weight, total calories expended is most important, and this is a product of duration and intensity," Gaesser adds. "Since longer duration can usually be tolerated better than higher intensity, duration should be emphasized."
To boost cardiovascular fitness, on the other hand, you'll need to elevate your heart rate, working at higher intensities and, therefore, taking more time off between difficult workouts; 25-45 minutes of moderate- to high-intensity cardio four to five times a week should do the trick.
q Are long, slow, steady workouts better for burning fat?
a No. It is true that lower-intensity aerobic workouts burn a slightly higher percentage of calories from fat (versus carbohydrate), while burning lots of carbs during higher-intensity exercise usually leads to more fat being burned after exercise. However, when it comes to shedding body fat, it doesn't matter what form the calories are stored in or how quickly or slowly you burn them, Gaesser says. The only thing that counts is the total number of calories burned. Steady-state workouts take longer than higher-intensity workouts to get you to the same total, although you may be able to exercise longer at a lower intensity. "Ultimately, it doesn't matter whether you burn your calories long and slow or short and quick," says Cedric X. Bryant, Ph.D., chief exercise physiologist for the American Council on Exercise in San Diego.
q Is there one cardio machine that's most effective for burning calories?
a Only if you work at a higher intensity or stay on a particular machine for more time. The harder and longer you work, the more calories you'll burn, regardless of the type of workout. That said, you may be apt to exert more effort, and thus burn more calories, on certain pieces of equipment. According to a landmark 1996 study, machines such as the treadmill and stair climber raised heart rate more than machines such as the cross-country skier, rowing ergometer and stationary bike. These results could be related to familiarity with the activity demanded by the machine (i.e., for most people, walking, running and climbing stairs are more familiar than skiing and rowing). However, using the same machine day after day just because it could burn a few more calories may not be the smartest idea. "If your program has variety, you're less likely to become bored," Bryant says. "It also helps to prevent overuse injuries and can keep your body from adapting, so you may even see an increase in caloric expenditure." As Roberts says, "Once you've adapted, you stop improving. If you're not making progress, it's definitely time to change."
q How do I know which preprogrammed cardio workout to choose?
a It's really a matter of personal preference, Bryant says. Such preset workouts are essentially a marketing tool developed by equipment manufacturers. Interval workouts that include recurring changes in intensity may be slightly better from a calorie-burning standpoint, he notes. But for the most part, it boils down to how hard you work, which you can control by pushing a button to change the level or resistance, or by speeding up your pace.

Coated Tools Can Provide Double Output With Same Tool
The F. P. Schmidt Manufacturing Company makes accurately machined parts in high volume, directly from coiled wire stock, on automatic and semi-automatic machines of its own design and construction. These machines knurl, thread-roll, mill, swage, press and cut a variety of materials such as brass, aluminum, carbon steel, 52100 roller bearing steel, and types 303 and 416 stainless steel. Schmidt's products usually form part of everyday consumer items, such as appliances, toys, hand and power tools, plumbing and electrical supplies, office equipment and automobiles.
Each part the company manufactures has its own precision form tool profiled in the shape of the cut, and is made of either T5 or M4 tool steel. Because coated tools are claimed to exhibit high-surface hardness, resist corrosion, and have low coefficients of friction, F. P. Schmidt began researching and sampling various coatings, hoping to reduce their production costs. Based on their findings, they selected Titankote-C, manufactured by Richter Precision, Inc., 1021 Commercial Ave., East Petersburg, PA. This coating is a physical vapor deposition (PVD) titanium nitride (TiN) coating at thickness of 0.0001-inch on each side of the tool.
PVD coatings, such as Titankote-C, are produced in a vacuum chamber at low temperatures as low as 650[degrees] F. In the vacuum chamber, TiN ions are transported by physical means, although they may be "directed" by polarizing the tool surface. The force of the TiN ions bonds the coating to the metal surface Although tools can be coated before or after sharpening, Schmidt decided to coat their tools before sharpening. In practice, and coating covers the side of the tool that wears most, while the front rake remains uncoated. These particular tools have between a 15-degree to 25-degree rake angle, depending on the material and the finish the customer requires.
F.P. Schmidt found that coating not only improves their own form tools, but those in a secondary operation, such as milling cutters, as well. One product operation requires milling the punches for paper punches. These steel punches are cut to form and shape on automtic machines. A V-shaped groove is milled in the one end that is to punch the paper. The punch is then heat treated. Finally, the finished cutting edge is ground in a centerless grinding operation.
The company says that after coating their tools, they notice an increase in tool life. Tools that previously turned out 200,000 workpieces now turned out 500,000 to 600,000 workpieces. In addition, this increase in the number of workpieces includes a variety of materials ranging from aluminum and brass right up to 52100 roller bearing and 303 and 416 stainless steels.
The company feels that utilizing a coated tool coating is relatively inexpensive when compared to the cost of a new tool, even if there is only a marginal increase in tool life. If a coated tool lasts longer than an actual second tool, then any use of the tool after that is all savings. Increased production per minute and better finish, at a lower cost, are the reasons F. P. Schmidt has been coating their tools for four years.

New machine guarding policy
The Mine Safety and Health Administration (MSHA) has come out with revised guidelines on how mining operations may safely and lawfully guard machinery and equipment. In MSHA's "Guide to Equipment Guarding," revised 2004, MSHA has done several things that are hoped will provide more flexibility to mine operators.
Possibly the most significant thing about this guide is that it recognizes for the first time the lawfulness of what has been called "area guarding." If properly constructed, implemented and maintained, guards that cover multiple pinch points will be accepted by MSHA as lawful compliance. The guide provides details on what would be necessary to protect multiple pinch points with a single guard It must be remembered that policy is just that. It is not law. Unlike a regulation, which is law because it is developed according to procedures prescribed by Congress, policy may be adopted by an agency without the safeguards of mandatory procedures for rulemaking.
For MSHA to make rules that have the force of law, it must follow all the procedures prescribed by Congress in the Mine Act. These procedures allow the public and all regulated parties ("stakeholders") to: 1) have an opportunity to be informed in advance, by public notice (in the Federal Register), of what rules and standards are being proposed; 2) have an opportunity to comment on those rules and have their comments considered; and 3) have an opportunity to immediately challenge final rules in court after they are finalized by the agency.
In making policy, on the other hand, there is rarely even a semblance of such safeguards. Usually, MSHA simply announces how it thinks a regulation should be followed. However, in the case of the new guarding policy, MSHA worked closely with the National Stone, Sand and Gravel Association to respond to the many issues the association had brought to its attention.
In rulemaking, the agency tries to achieve a rule that is clear and says exactly what the agency believes should be required. Many rules turn out to be less than completely clear and that is when the agency tries to explain what it thinks is required under the rule. That is where policy comes in. It explains what the agency says the regulation means and how the agency thinks the requirements can and should be met.

Plungers for Fast, Effective Machining of Cavities - machine tools from Iscar Ltd - Brief Article
ISCAR presents its new milling concept for plunging with high material removal rates. This system incorporates a combination of drilling and milling operations into a single tool. When plunging, the tools are subjected mainly to axial forces -- with minimal radial forces compared to those involved in conventional side machining of cavities. Machining in the axial direction results in increased stability, higher feeds and longer tool life.
This new tool provides efficient metal removal rates in a variety of applications, including the machining of deep cavities, high shoulders, slots, and straight or sloped walls.
Three types of cutters available: one is for plunging into solid material--similar to a drill--in the axial direction only. The second is for plunging but, as a trepanning tool, with a central hole to improve performance. The third is based on HELIQUAD inserts for side plunging with a limited frontal width and for finishing with side cutting.

Faster machining
The approach is to have a series of LTCs (four- and six-spindle configurations are available) setup in a line. Each of the machines is tooled to perform a limited number of operations, unlike the typical case in a machining center-based line (parallel processing), wherein a single machine typically performs all of the operations required to finish a part. So what happens in an LTC system is that the part, which is fixtured to a pallet (which provides the opportunity for five-axis machining through part positioning), undergoes metal removal in a series of machines that can provide "toolchange" in 0.8 seconds, which means positioning another of tooled spindles to the work, not changing discrete tools from toolchanger to spindle. This is a serial processing approach.
Benz admits that in addition to being quick, this approach is somewhat more expensive if there is a simple comparison made of, say, machining center to LTC. But he notes, "Price isn't everything," and goes on to point out that what needs to be taken into account is "the total cost of ownership."
In other words, if it is possible to produce parts much more quickly--in one time study on an aluminum steering knuckle, the job required 143 seconds with machining centers and could be done in 45 seconds with three LTC six-spindle machines integrated with a rotary part transfer device--then the investment may be well spent, Benz adds, "Our machines are used where labor costs are high." Which means that they're used in places where the machinery and equipment need to be exceedingly productive.
On The Web - automated machine tools using Internet - Brief Article
On occasion, we here at OTW notice "things" that help define an online trend for our industry. These examples are often companies or products that come along and suggest the Web's potential for metalworking.
Well, nothing has caught our online attention more effectively than the potential of "Web-enabled Machine Tools." And activities at two companies suggest that progress in this area is far from comatose.
eMation is a "new" company that espouses Device Relationship Management (DRM). More than just another acronym, the DRM applications are said to transform machine tool data--temperature, fluid levels, tool condition, spindle performance, part run schedule, or any machine condition--into "business intelligence." Simply put, this system defines progress toward applications that allow for more efficient monitoring, maintenance, repair and management.
e-manufacturing Networks, Inc. (www.e-manufacturing.com) has been around for a while. It has been spreading the "Machine Is A Node On The Network" gospel for some time. But this Canada-based company has recently introduced a new line of after-market products that Internet-enable the machine tool through its control. Now, we aren't saying these companies are preferable to others; many OEMs, distributors and suppliers are pursuing their own, noble Internet-enabling efforts. But the efforts of these and other developers suggest strong Internet technology advancements for our industry.

Automatic Messaging From The Machine Tool - Brief Article
Users of CNC Professional, the company's PC-based CNC machine tool controller software for Windows, are said to now have an added benefit. A machine tool will automatically call the user's cell phone or pager and send a detailed text message on the status of the machine.
The messages from the machine tool can be any ASCII text message, alphanumeric message or tone signals. The messages can be initiated and/or triggered by almost any event. Perhaps an error occurred, M code, end of program, completion notice, number of parts made, laser power, low voltage, loss of motor control or any certain user interaction. Users can arrange for their machine tools to send messages at regular time intervals so that they can receive machine updates. A complete list of national and international SMS (short message service) service providers for all major cell phone and pager carriers is included.

Large Halogen Machine Lights feature dual lens design
Equipped with double glass lenses, HGW series is comprised of 18 and 32 in. arm models for broad work areas and head only model (HGWK) for compact work areas. Having inner and outer glass lens enclosed in one machine light protects lamp from breakage and causes outer lens to remain cooler. Viewing area stays clear of coolant and other fluids, maintaining consistent illumination of application at hand. Series comes with 12 V, 55 W lamp, or 24 V, 60 W halogen lamp.
Wheeling, IL-Waldmann Lighting Company's Large Halogen Machine Lighting series now features double glass lenses included with all luminaires. Having both an inner and outer glass lens enclosed in one machine light protects the lamp (bulb) from breakage, and causes the outer lens to remain cooler since there is a thermal barrier between the two lenses. This barrier helps to prevent coolant and other chemicals from baking onto the outside lens, and heat generated from the halogen lamp (bulb) is absorbed by the inner glass lens only. Operator safety is also improved because the viewing area stays clear of coolant and other fluids that may be prevalent, and the light consistently illuminates the application-at-hand. See our cooler halogen HGW and our entire line of machine tool lighting solutions at the Westec Trade Show in Los Angeles, California, on March 27-30.
This new standard double lens is available on Waldmann's 18-inch and 32-inch arm HGW for broad working areas. A "head only" (HGWK) double lens model is offered for compact work areas where space is limited. Other features of the HGW double lens series include either a 12V 55-watt lamp, or a 24V 60-watt halogen lamp with polished reflector that provides high intensity light and an estimated lamp life of over 3500 hours. An ergonomically designed handle and heat shield attached to the head provides safe and easy positioning. The light also includes a 4-hole pattern mounting base. All 120V versions include a remote transformer in a waterproof case for plug-in to a 120V power supply.
All HGW Halogen Machine Lights are ideal for heavy coolant environments and provide IP-65 waterproof protection. The lights are used for CNC machinery, conventional mills, lathes, and other metalworking machinery and machine tools. The lights are also ideal for packaging machinery and food processing equipment where coolant, oil, and other fluids are present. The "head-only" models are ideal for grinders, machining centers, CNC lathes, screw machines, turning centers, and packaging and processing machinery where space is limited.

Faster machining
When Winfried Benz, managing director, LiCON[MT] (Laupheim, Germany; Ann Arbor, MI; www.licon.com), relates the types of systems and machines that the company has provided to companies (Volkswagen is a big customer) for a variety of parts, ferrous and nonferrous alike, it becomes clear that there is a focus on high uptime, especially as he's talking about equipment that typically runs in the range of 100,000 to two million parts per year. When you get to those kinds of volumes, then whatever time the spindles aren't removing metal is time wasted. So they have developed a machining module called the "Linear Tool Changer" (LTC) that reduces toolchange time to less than one second. That's right: less than one second.
This isn't predicated just on a mechanism but, rather on a rethinking of what is actually occurring in conventional high(er) volume applications. That is, LiCON[MT] engineers have calculated that in the typical production machining operation, the cutting cycle time for a given tool is on the order of three seconds. What's more, they've determined that overall, there are fewer than 20 tools used to machine a given part. So instead of the approach that is often used by machine builders, which is to provide a means where tools can be swapped in and out of the spindle in, say, three seconds, what they've done is essentially eliminate the automatic tool change--which is, perhaps, more astonishing than the one-second time. In this case, "toolchange" means using another tool. And the other tool is fitted to the spindle head that is part of the LTC.
Essentially, each head, which has four to six CNC spindles, is powered all the time by a 15-kW motor (standard). Spindle speeds (standard) of up to 10,000 rpm can be achieved on the four-spindle version; 15,000 rpm on the six-spindle. Distances between each of the spindle centers is 160 mm. Maximum tool diameter is 125 mm. The axis travels are 400 X 400 X 630 mm for the four-spindle version; 600 X 600 X 800 for the six-spindle style; the positioning accuracy and repeatability are 0.01 mm and 0.005 mm, respectively. Rapid traverse can be performed at 60 m/min. The approach is to have a series of LTCs (four- and six-spindle configurations are available) setup in a line. Each of the machines is tooled to perform a limited number of operations, unlike the typical case in a machining center-based line (parallel processing), wherein a single machine typically performs all of the operations required to finish a part. So what happens in an LTC system is that the part, which is fixtured to a pallet (which provides the opportunity for five-axis machining through part positioning), undergoes metal removal in a series of machines that can provide "toolchange" in 0.8 seconds, which means positioning another of tooled spindles to the work, not changing discrete tools from toolchanger to spindle. This is a serial processing approach.
Benz admits that in addition to being quick, this approach is somewhat more expensive if there is a simple comparison made of, say, machining center to LTC. But he notes, "Price isn't everything," and goes on to point out that what needs to be taken into account is "the total cost of ownership."
In other words, if it is possible to produce parts much more quickly--in one time study on an aluminum steering knuckle, the job required 143 seconds with machining centers and could be done in 45 seconds with three LTC six-spindle machines integrated with a rotary part transfer device--then the investment may be well spent, Benz adds, "Our machines are used where labor costs are high."
