Abstract
Online machining precision evaluation is of great significance for lowering manufacturing cost and improving manufacturing efficiency. The open numerical controller provides an opportunity to access the signals of servo drivers during the machining process and makes the online monitoring of the machining process realizable. In this paper, a novel online evaluation method of the work piece machining error is proposed based on homogeneous coordinate transformation and built-in signal testing technology. A gear grinding process is monitored experimentally, and it is shown that the proposed method is effective at detecting work piece machining errors.
