Purpose

This specification is intended to serve as a guide in the coordination of system design, to minimize the variety of program manuscripts required, to promote uniformity of programming techniques, and to foster interchangeability of input tapes between numerically controlled machines of the same classification by type, process function, size, and accuracy. It is intended that simple numerically controlled machines be programmed using a simple format which is systematically extensible for more complex machines.

Classification

This standard applies where ever variable block format is used on perforated tape to control numerically controlled machines. (Note: This format will usually be used with tape read row-by-row.)

Class III, positioning and straight cut numerically controlled machine/controller.

Class IV, continuous path or contouring/positioning numerically controlled machine/controller.
