Isolating cutting operations: Turning Performance
The accurate positioning of the cutting tool with respect to the workpiece partly controls the accuracy of a machined part.
Apparent mass of moving machine elements
The moving elements of a machine tool have mass. Forces from the actuators cause the masses to move and accelerate. As the speed of the machine tool motion increases, the ability of the actuators to cause acceleration becomes more important.
Managing multiple milling constraints
The Machine Technology column from the April 2011 issue of Cutting Tool Engineering magazine suggests that successful milling requires managing multiple constraints.

Three rules for cutting thin parts
In recent years, monolithic machined aluminum components have been replacing sheet metal assemblies throughout the aerospace industry. The monolithic structures are lighter, less expensive and stronger than their conventional sheet metal counterparts. Machining the components requires fewer special tools, fewer hand operations and less assembly time.
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.
Some measurement required: Research & Innovation
Machine tool users can access the information contained in a stability lobe diagram to greatly increase productivity.

Using Stability Lobe Diagrams to Control Chatter
Stability lobe diagrams help shops estimate spindle-speed zones that reduce chatter risk. This guide explains what they show and how to use them practically.
