ABSTRACT:
A method and apparatus for producing relative arcuate movement which may be greater than one quadrant for each input command by subdividing the movement into a plurality of sequential linear lengths of varying extent and proper direction. The extent of each length is defined by the number of steps of movement to be produced simultaneously over the same time interval on each of the pair of perpendicular axes. The extent of each length is determined to be that which both maintains the actual movement within a maximum deviation from the commanded path and is within the change of velocity limitation of the system thereby inherently providing acceleration and deceleration as well as not excessively exceeding any feed rate command.
The method and system further selects the extent of the length from a group of possible extents by investigating which extent is most acceptable having regard to relative emphasis of path deviation and velocity error. The relative emphasis may be set by input commands.
