One of the important functions of a milling machine is to cut slots, grooves, or teeth that are to be equally spaced around the circumference of a blank. The process of dividing a part (blank) into equal spaces is called indexing. In particular, gear cutting involves a great deal of indexing. For indexing, the blank (workpiece) is held and rotated by the exact amount for each groove or teeth (to be cut) by use of a dividing head or indexing head (see Figure 7.10).

To ensure that the experiment is reliable, an as-built model is required for the rack being scanned. The original CAD model provided by KHK cannot be used, as it only includes three effective teeth, whereas there are in total of five teeth physically presented on the rack. In addition, the CAD model may not accurately represent the as-built part. Hence, for this experiment, a coordinate measuring machine (CMM) machine is used to produce the as-built model. CMM machine is commonly used as an industrial standard for inspection due to its high accuracy. The CMM used in this paper is a three-axis CMM, the Mitutoyo Beyond-Crysta C544 with PH10M Indexing Head and TP200 Probe, and is used together with the accompanying software MCOSMOS v2.4 with SCANPAK.
