A control device of a machine tool ( ) has an input unit ( ) for inputting the processing profile data ( ) and the workpiece data ( ) of the material and a profile of the workpiece to be processed. The control device input unit ( ) also can receive a tool path changing operation command ( ), a manual operation command ( ) and a processing condition changing command. A data base ( ) for storing at least one of the mechanical data of the machine tool to process the workpiece and the tool data of the tool mounted on the machine tool provides a signal to an estimating calculation unit ( ) for estimating at least a processing load or the occurrence of interference of the tool with the workpiece based on the data inputted by the input unit ( ) and the data stored in the data base ( ). A tool path deciding unit ( ) calculates a tool path to process the workpiece and decides processing conditions such as spindle rotating speed and the feed speed for the machine tool ( ) based on the output of the estimating calculation unit ( ).

Machining apparatus

A control apparatus for a machine tool comprises input means for inputting machining profile data on the final profile of a work and workpiece data on the material and profile of the workpiece to be machined, data storage means for storing at least one of machine data representing machine specifications of the machine tool for machining the work and tool data representing the specifications of the tools held in the machine tool, and tool path determining means for generating a tool path for machining the work and determining the conditions for machining the work including the rotational speed of the main spindle and the feed rate of the machine tool based on the data input from said input means and the data stored in said data storage means.
