Title:
THREE-DIMENSIONAL COORDINATES CONVERSION CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/1991/010944
Kind Code:
A1
Abstract:
A three-dimensional coordinates conversion control system in a numeric controller for controlling a machine tool having a plurality of heads. Pre-treatment calculation means (2) decodes a machining program (1) and executes coordinates conversion for only a first head by three-dimensional coordinates conversion means (3) and pulse distribution means (4) distributes pulses of this coordinates value. The coordinates value for the first head is used as such for a second head and the pulse distribution means (5) distributes pulses. In this manner, the number of calculations of three-dimensional coordinates conversion is reduced and the load of operational processing of the numeric controller is reduced, too.
