ATTITUDE CONTROL METHOD FOR CNC LASER BEAM MACHINE

摘要

PURPOSE:To simplify a program making without the need for thinking of accompanied turning at program making time by composing the title method so as to correct automatically the accompanied turning of a beta axis by the movement of alpha axis. CONSTITUTION:Due to each axis being not completely locked after cutting a power source unless composed by a complete closed loop generally it is necessary to execute an origin return after reinput of power source. However it is unnecessary to execute the origin return by calculating the movement amt. of after power source cut by following up the positional information of servomotors 1, 2. But concerning the beta axis it is necessary to correct the movement of the axis by the accompanied turning on the following-up. The accompanied turning of the beta axis can therefore be corrected by taking the followup amounts (a), (b) of the alpha axis and beta axis as a1 and a1+b1 at the time when the followup amt. of the alpha axis and beta axis from a machine side is taken as a1 and b1.
