ABSTRACT:
An advanced memory type profiling control method for a machine tool including a tracer which is relatively moved along a surface of a model and a machine body provided with a cutting tool such as an end mill whereby a work having the same shape as that of the model is made, includes driving the tracer along the model surface with the tracer preceding the machine body by a predetermined time, sampling coordinate data of a position of the tracer and data of displacement of a stylus, which is moved in contact with the model surface, to the tracer at a predetermined sampling time, calculating coordinate values of points on a locus formed by a movement of a central point of the stylus ball on the basis of the sampled data, calculating a coordinate value of a point following the central point of the stylus ball at retard, for each sampling time to obtain a command position data to the machine body, storing the command position data in a memory successively, and supplying the stored data to a drive control unit of the machine body successively with a predetermined delay time after storing the data.
