Performance Evaluation of Rotary Table Using an Angular Indexing System with Self-Calibration Technique

The angular error of indexing table on machine tool is measured using new developed measuring device. The measuring techniques, which have been reviewed in this paper, are currently available in manufacturing engineering to calibrate the angle measurement. The new developed measuring device using 6 points kinematic concept and employing ball and vee grooves is used to calibrate angle errors of rotary tables using a laser interferometer. Compact new automatic indexing table was achieved by driving the cam mechanism. The design for an automatic indexing table is considered to be satisfactory for company to calibrate rotary table. This automatic system gives the time saving during measurement process. The equipment required for economical manufacture is relatively simple and could be undertaken by most machine shop Keyword-Indexing system, rotary table, Self-calibration, Interferometer, Kinematic Design
