Watch the 12th episode of Cutting Tool Engineering magazine's Grinding Doc Video Series as host Dr. Jeffrey Badger helps a shop decide if it's a bad idea to gauge whether it gets burn by looking for burn marks on the part.

A grinding shop trying to grind a 0.006" radius into a hardened steel part with a 60-grit, vitrified-bond, aluminum-oxide wheel was having trouble with burn and huge chatter. Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, explains how to handle the situation in the 11th episode of the video series.

Flowdrill Inc. provides a video demonstration of its thermal drilling process. The company produces tungsten-carbide bits and roll-form taps to thermal drill and then thread holes in malleable materials.

Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, looks at improving coolant velocity for shops running into loading problems with superabrasive wheels. Such wheels are more problematic than aluminum oxide wheels that wear away more readily, Badger reports in the 10th episode of the video series.

Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, tells shops not to be timid when sticking a wheel. By sticking aggressively, shops can do more parts between wheel sticks, the Grinding Doc suggests in the 9th episode of the video series.

Take a tour of the University of Wisconsin-Madison's Advanced Manufacturing Laboratory. As part of the 5th International Conference on MicroManufacturing (ICOMM/4M 2010) held at the university in April, attendees were offered an opportunity to visit the lab and get a first-hand look at current research efforts.

Focus Variation, the technique behind Alicona's Infinite Focus 3D optical metrology system, has enabled EDM Department, Bartlett, Ill., to measure and see what it is making down to 1.7µm tolerances. Watch this brief report to see the system in action and learn about how EDM Department implemented the system.

Video of Becker PCD Chipbreaker inserts sold by Rani Tool Corp. eliminate bird nest chips when turning aluminum.

Video shows Becker CBN inserts being used to hard turn 62Rc d2 steel. The inserts are sold in the U.S. by Rani Tool Corp.

Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, urges shops to dress quickly and take deep cuts to reduce cycle times in the 8th episode of the video series.

Machining molds typically involves creating complex contours and fine surface finishes. Molds are high-value items usually produced in single-digit volumes, making gradual process development and scrapping parts a costly exercise. Moldmakers' customers generally want to get their products to market as fast as possible, so lead times can be short and inflexible. Finally, overseas competition puts added pressure on U.S. shops. Moldmakers are facing the challenges with a combination of technology and teamwork, and CAD/CAM software is a key competitive tool.

When cylindrical OD plunge grinding, Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, says you can play around with the parameters without affecting cycle time. Watch the 7th episode of the video series now.

When Seco Tools Inc. moved into its new headquarters in Troy, Mich., in July 2008, the toolmaker not only changed buildings, it also changed its corporate culture. Eighteen months after the facility opened, the company is still finding new uses for the modern, light-filled, 81,000-sq.-ft. building, according to Bob Goulding, manager of component engineered tooling and custom tooling.

What's a good speed when cylindrical OD traverse grinding? Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, worries less about the speed, more about the percentage of the wheel being used to do the roughing in the 6th episode of the video series.

Machining components for solar power generation systems can be a renewable source of business. Included online is a video report from the National Renewable Energy Laboratory.

Precision Dormer filmed its R571 CDX-DH "One-hit" Deep-Hole Drillmaking holes 102mm deep at a speed of 157mm/min. and feed rate of0.14mm/rev.

A Studer brand S242 machine, which combines hard milling and grinding, is shown hard milling a toolholder without coolant, then grinding the holder's taper with coolant to achieve the required surface finish.

Iscar designed drills for small-diameter, deep holes in automotive crankshafts, camshafts, connecting rods and more—all with minimum quantity lubrication.

Thinking about using cluster diamonds? Dr. Jeffrey Badger, the host of Cutting Tool Engineering magazine's Grinding Doc Video Series, suggests going at least 4x faster than with a single-point diamond in the 5th episode of the video series.

Rather than using taps to thread steel prior to hardening, a growing number of shops are opting to thread mill heat-treated steel.
