ABSTRACT:
An offset path generating system is described for generating in Cartisian coordinates a prescribed offset, or deviation, from a programmed path at the same time the original path is being generated. The described apparatus is particularly useful for generating the tool center path of N/C machines, and includes: (1) an offset generating system, which generates X-axis and Y-axis drive pulses defining an offset path of motion offset from a programmed path by a prescribed magnitude, this being the radius of the machine tool; (2) a slope-discontinuity control, effective to control the offset path upon the inputting of a first programmed motion followed by a second programmed motion having a discontinuity in slope between them, such as in the case of corners; (3) an offset turn-on control effective, upon receiving an Offset-Turn-On Instruction, to disable the programmed path generator from generating the programmed motion while it generates offset axes-pulses at a prescribed velocity until the offset is at a right angle to the initial path of the programmed motion, at which time the programmed path generator is re-enabled to generate the programmed moton; and (4) an offset turn-off control effective, upon receiving an Offset-Turn-Off Instruction, to disable the programmed path generator from generating the programmed motion while it generates offset axes-pulses at the prescribed velocity to move the offset to zero, at which time the programmed path generator is re-enabled to generate the programmed motion.
