METHOD AND DEVICE FOR PROCESSING FRAME WELDED FROM PLASTIC OR METAL PROFILES

摘要

A method and a device for machining the corner joints of window or door frames welded together from plastic or metal profiles, comprising at least one cutting tool which can be moved by a tool carrier, having a scanning device, into its machining position at the frame (5) accommodated in a clamping fixture. In order to compensate for profile, welding and frame tolerances, in particular at the machining surfaces running parallel to the clamping plane of the outer corner of the frame, at least one machining surface (8, 9) running parallel to the clamping plane of the frame (5) is scanned and the measured value or values obtained in the process are converted as a regulated quantity or quantities for the orientation of the at least one cutting tool in a basic position at the workpiece. The scanning is effected in particular in the area of the outer corners of the frame (5) or its mitre. IMAGE
