Abstract

In machining, the workpiece fixturing is an essential task which often affects the quality of the final product. The actual approach of the fixturing error control is based on the correlation of the workpiece position with respect to the tool position and tool programmed trajectory. In this paper, a method for fixturing errors identification is proposed. This method is using input data which consist in the coordinates of points belonging to the reference surfaces. Using on-machine measuring system this input data is acquired and the position parameters of the references surfaces are determined. Data obtained from identification can be used for compensation of the fixturing errors. As a case study, a longitudinal turning process was considered. For the validation of the proposed method a numerical simulation program was conducted.
