CNC milling machines are usually assembled with five modular components: a machine base, saddle, table, vertical column, and headstock with a spindle tool unit. In the spindle tool system, the feeding mechanism of the control axis is constructed in various configurations using linear guides, ball screws, and supporting bearings [9], [10] .

Machining cam lobes | Model Engineer

I want to machine some cam lobes on the milling machine and I seem to remember a program that gave a list of co-ordinates in the z axis relative to a radial movement. This gave a stepped profile which needed a light dressing with a file. Can anyone shed any light on this or any other way of producing a cam lobe.
