Computer aided predicting of surface finishes before machining

الملخص EN

The profile of a machined surface depends on at least three processes; the kinematics or motions in the machining process, dynamic behavior or vibrations of the machine-tool-work system and the material deformation process as the chip is formed The surface produced due to the feed motion (kinematics) of the cutter along the workpiecce will be considered in this paper.

A turning data base system is prepared in order to determine feeds from machining data for a number of different materials.

The other step in this work is to develop a computer program for predicting surface finish for turned parts.

The importance of work results is to automate the process of finding estimated values of surface roughness before machining.

So it is a helpful indicator when choosing cutting conditions to machine a part within certain surface finish.
