scope:

This part of ISO 230 specifies test procedures to evaluate the measuring performance of contacting probing systems - used in a discrete-point probing mode - integrated with a numerically controlled machine tool. It does not include other types of probing systems such as those used in scanning mode or non-contacting probing systems. The evaluation of the performance of the machine tool used as a Coordinate Measuring Machine (CMM) is outside the scope of this part of ISO 230. Such performance involves traceability issues, is strongly influenced by machine tool geometric accuracy and shall, in addition to the machine tool probing system tests specified in this part of ISO 230, be evaluated according to ISO 10360 series of standards. Numerically controlled machine tools may currently apply contacting probing systems in machining process applications such as: - Identification that the correct workpiece has been loaded before machining; - Location and/or alignment of the workpiece; - Measurement of the workpiece after machining but whilst still on the machine; - Measurement of the location and orientation of the machine tool rotary axes; - Measurement and setting of the cutting tool (radius, length and offset of the tool); - Detection of broken tools. NOTE 1 - The first version of this standard will focus on machining centres, but later versions will include other types of machines like turning and grinding centres. NOTE 2 - The first version does not include non-contacting type of probes (e.g. optical probes) or scanning probes. Future version of this standard will include those.
