Method and device for processing workpieces which use conoscopic holography

摘要

The method involves clamping a workpiece in a processing machine i.e. precision grinding machine, and measuring a surface area of the workpiece using an optical measuring device (30) e.g. laser triangulation sensor, in a contactless manner while the workpiece is clamped in the machine. The workpiece is processed, and a product is accurately measured. Measurement data corresponding to the measured product is utilized for manufacturing additional products. The data is stored and utilized as control data for processing the workpiece and as reference data for measuring the processed workpiece. An independent claim is also included for a device for processing a workpiece.
