Can-do coolant strategies
With the cost of high-performance coolants on the rise, coolant management is more important than ever. It starts by getting the basics right.
Grow in the dark: CMM Inspection
Even low-volume operations producing many different parts can benefit from lights-out production.
Driving diesel developments: Drilling Performance
Machining large compacted graphite iron castings for diesel engine components is challenging, but applying the proper tools and techniques can help.

Cooling: Velocity or flowrate?
The debut episode of Cutting Tool Engineering magazine's Grinding Doc Video Series fields a question from a shop wondering about the relationship between coolant velocity versus the flowrate. Dr. Jeffrey Badger, the host of the video series, takes a look at the coolant issue.

Post-processing should not work: Design & Engineering
The creation of a part program for a CNC machine tool usually starts with a part drawing or model that contains the part material, geometry and tolerances.
Grinding Doc: Using the Ra eyeball technique
Dear Doc: I grind small parts with intricate geometries. I'd like to get a handle on what kind of Ra values I'm generating and if the grinding process changes I'm making are improving or worsening the surface finish. I was told to purchase a profilometer. Is this the best route to go?
Reaching the apex: Drilling Performance
Combination tooling, custom fixtures and creative solutions help Apex Precision thrive.
High anxiety: Drilling Performance
Understanding tool geometry and selecting the right tap for different workpiece materials can help take the anxiety out of tapping operations.
On tap
Check out this brief video from Kennamental Inc. showing a side-by-side comparison of an HSS tap vs. a solid-carbide tap. The video accompanies CTE's August cover story on selecting the right tap for different workpiece materials. The split-screen video demonstrates the significant productivity advantage of the first solid carbide tap specifically engineered for tapping steels.
