Analysis and control of dimensional precision in turning process
The aim of the present work is to evaluate dimensional precision in turning process. A new model of dimensional error taking into account of flank wear and spring back of machined surface of workpiece material was proposed. Flank wear land, tool nose radius and clearance angle are the crucial control parameters in this model. According to the proposed model, the dimensional error was calculated using flank wear land obtained from previous experimental results. The role of three control factors on determining dimensional error has been investigated. The calculation of dimensional error coupling with predict model of flank wear can realize the pre-estimation of dimensional precision in machining.
