Machine Technology

The Machine Technology column from the April 2012 edition of Cutting Tool Engineering magazine examines how machine tool vibration often causes problems when machining. Chatter, a self-excited vibration, can lead to poor surface finish and cutting tool chipping or breakage.

Machine Technology column: A machine tool bed serves several important functions. It supports the machine's moving elements and supports them in geometric relation to each other. The relationship between the moving elements is more important than the relationship between the moving elements and the ground the machine is based on.

Measuring or modeling the natural frequencies and mode shapes is a useful step in avoiding or eliminating vibration problems.

The Machine Technology column for the January 2012 issue of Cutting Tool Engineering focuses on developing an understanding of the role of drawbar force.

High-speed machining requires hybrid spindle bearings.

The Machine Technology column in the August 2011 issue of Cutting Tool Engineering takes a close look at measuring the cutting force.

The Machine Technology column in the July 2011 issue of Cutting Tool Engineering magazine takes a look at how the precise control of axis position works.

The June Machine Technology column in Cutting Tool Engineering covers selecting and maintaining preload in spindle bearings.

The Machine Technology column in the May 2011 issue of Cutting Tool Engineering suggests that maximum spindle speed may not be the best option.

The Machine Technology column from the April 2011 issue of Cutting Tool Engineering magazine suggests that successful milling requires managing multiple constraints.

The Machine Technology column from the March 2011 issue of Cutting Tool Engineering eyes importance of establishing a warning track for a machine tool's stability limit.
