Dr. Jeffrey Badger provides a simple, if not pretty, solution to a nasty cylindrical grinding problem — when the side of a grinding wheel meets a flat surface. Watch the 103rd episode of the Grinding Doc video series.

UNISIG, Menomonee Falls, Wisconsin, demonstrates why trepanning is beneficial when drilling deep holes that are too large for high-pressure coolant drills or gundrills. Utilized in the aerospace, defense, material production, as well as oil and gas industries, trepanning reportedly offers higher productivity in many applications and uses less power than other drilling strategies.

Presented as a video supplement to Cutting Tool Engineering's July 2020 article that addresses the need for part manufacturers to work with toolmakers to learn about the wide range of tool options available today, "Illuminating Aluminum" offers two machining demonstrations from LMT Onsrud LP, Waukegan, Illinois, and RobbJack Corp., Lincoln, California.

For the 102nd Grinding Doc episode, Dr. Jeffrey Badger covers the impact that thermal softening, residual tensile stresses and rehardening burn have on fatigue life in steel workpieces.

Jeffrey Badger, Ph.D., takes a detailed look at the impact different grinding approaches have on cup wheel wear in the 101st episode of the Grinding Doc video series.

This video supplement to Cutting Tool Engineering magazine's June 2020 Productive Times article showcases the solution provided by Güdel Inc. — automated material handling through the use of a double-axis gantry robot with special grippers.

ProvenCut recipe 551 shows how to achieve a high material removal rate while maintaining a reliable cut using a light-duty machine with a 6.35 mm (0.25") endmill to slot 4140 alloy steel.

Iscar Metals Inc. in early March presented a series of milling and drilling demonstrations during the company's 2020 Milling & Holemaking Seminar at its Tech Center in Charlotte, North Carolina.

Precision Tool Technologies Inc., Brainerd, Minnesota, developed the FullShop automated coolant delivery system to eliminate manually monitoring and replenishing coolant so that the shop could enable unattended machining.

In the 100th episode of CTE's Grinding Doc video series, Dr. Jeffrey Badger discusses his least favorite subject—chatter.

Using a Tormach 1100 CNC mill, ProvenCut demonstrates Recipe 502, a Fusion 360 adaptive roughing strategy run at 12.2 m/min. (40 sfm) and 0.033 mm/tooth (0.0013 ipt) with a 15.875 mm (0.625") axial DOC (ap) and 0.508 mm (0.02") radial DOC (ae).

The DC160 carbide drill features exceptional positioning accuracy.
