MATERIAL REMOVAL PROCESSES

For industry to operate effectively, the material that produces the final product must be machined and formed quickly and accurately. The key factors that affect the efficiency of a metal-removal process are the machine tool, the controller, spindle, toolholder, cutting tool, and CNC programming. High Speed Machining (HSM) uses high spindle speeds, high feed rates, and light depths of cut to increase productivity, reduce lead time, reduce warping, increase part accuracy, and improve surface quality.

In virtually all metal-removal operations, manufacturers are trying to reduce the amount of time a part is moved from machine to machine and perform more operations in a single workpiece setup. This has led to the development of new machine tools such as the turning center with live tooling and special workholding fixtures where both turning and milling operations can be performed in one part setup.
