Title:
COPYING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/1992/013676
Kind Code:
A1
Abstract:
A tool is made to copy a model, following the same path as that of a tracer head which copies the model, and lagging the tracer head by a predetermined time in order that a cutter doesn't bite a work at a corner part. On each axis of a machine tool, the tracer head is driven independently of the tool by sub-motors additively provided on the feed shafts for the tool. Copying command values are stored in a FIFO memory (41), and are outputted to each axis of the machine tool at predetermined time intervals. In a computing circuit (43), speed command values (Vxs) for the sub-motors are computed from the copying command values. According to these speed command values (Vxs), the tracer head copies the model, preceding the tool.
