Mathematical Model of Topology Modification of Tooth Surface and Error Characteristics

Abstract

In order to analysis the processing performance of the CNC grinding machine, the master profile error distribution characteristics of gear grinding tooth error analysis method based on statistical process control techniques. Tooth profile error topology control charts, analysis of the tooth length direction and the tooth height direction of the error distribution, respectively, corresponding to establish the mean - range control chart. Control charts to achieve real-time distribution of the gear grinding process tooth profile error, error change trend analysis and prevention. Calculate the machine's process capability index, derived CNC grinding processes. Finally, analysis the main causes of tooth profile error and take appropriate measures to reduce the tooth profile error by the cause and effect diagram.
