Abstract
A method of simulation of NC machining, wherein machining simulation is carried out according to blank shape data, tool shape data and an NC program to modify the NC program or interpolation data by feedforward control so that optimum cutting conditions can be obtained. The simulation result can be used for correcting the NC program and the interpolation data at the next stage. Further, a record of tools used can be generated on the basis of this simulation result.
