    摘要： The system described is particularly useful for tracing a twolobed epitrochoid contour in order to produce this complex shaped housing for the Wankel rotary engine. The system generates the precise tool-center path in the form of incremental motion command pulses which are supplied to X-axis and Y-axis positioning systems to effect the relative displacement of a tracing tool (e.g. a cutter or grinding wheel) with respect to an object (e.g. the workpiece) to trace on the latter the two-lobed epitrochoid surface, and at the commanded feedrate velocity. The system described is a hard-wired one arranged to perform all the operations in parallel to achieve a very high output rate. The required calculations are performed by approximation techniques involving only simple addition, subtraction or numerical comparison, but no trigonometric operations.

    摘要： 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.
