This standard 21/30413996 DC BS ISO 230-4. Test code for machine tools is classified in these ICS categories:
  • 25.040.20 Numerically controlled machines

This document provides methods for the determination of the contouring performance of numerically controlled machine tools.

This document specifies methods of testing and evaluating the bi-directional circular error, the mean bi-directional radial error, the circular error and the radial error of circular paths that are produced by the simultaneous movements of two linear axes.

This document also specifies methods of testing the deviations of the circular or constant radius trajectories generated by any combination of simultaneously controlled (coordinated) linear and rotary axes. The basic principle of these tests is to coordinate the multiple axes of motion (combination of rotary and linear axes) to keep the relative position between the tool and the workpiece constant.

Annex A describes differences between circular errors and radial errors, Annex B influences of typical machine errors on circular paths executed with two linear axes, Annex C precautions for test setups for circular tests with rotary axes, Annex D shows an example of adjustment of diameter and contouring speed, and Annex E describes circular tests using feedback signal.
