Abstract
The machining of mechanical pieces in a grinding machine is controlled depending on in-process and post-process measurements of the pieces. The post-process measurement is carried out by using the same in-process measurement means, with the provision of different zero references for the two types of measurements.
Claims8
A method for controlling the machining of mechanical pieces in a machine tool, like a grinding machine, comprising the steps of in-process measuring the pieces by measurement means in order to obtain a first measurement signal;
- a first comparing step, for comparing the first measurement signal with a first reference;
- controlling the machine tool depending on the result of the first comparing step;
- post-process measuring the pieces by the same measurement means used for in-process measuring, in order to obtain a second measurement signal;
- a second comparing step for comparing the second measurement signal with a second reference;
- and correcting the first reference depending on said second comparing step.
