Abstract
The invention relates to an apparatus for controlling a machine tool during the machining of a first workpiece to be matched with a second workpiece already machined. The purpose of the invention is that of solving the problem to obtain the desired play along the entire matching section. For grinding a shaft to be matched with a bore, the apparatus comprises two pairs of measuring heads which check corresponding diameters of the shaft and of the bore, near their ends, a control unit for correcting the shape error of the shaft, preferably after a spark-out phase and before finish-grinding, and a control unit which controls the finish phase for obtaining the desired play.
Claims11
Apparatus for controlling a machine tool during the machining of a part of a first workpiece to be matched with a part already machined of a second workpiece, comprising:
- first measuring means adapted to cooperate with said part of the first workpiece for providing a first signal and a second signal for checking respectively two dimensions on two distinct sections of said part of the first workpiece;
- second measuring means adapted to cooperate with said part already machined for providing a third signal for checking a dimension of the part already machined;
- and
- processing and control means coupled to the first and second measuring means to receive said first, second and third signal, the processing and control means being adapted to process the first and second signal for controlling and regulating the machine tool for correcting the deviations of the part of the first workpiece from a determined shape and to process the first and the third signal for controlling the machine tool for obtaining a pre-set matching between said parts.
