摘要:
A numerically controlled machine tool in which dimensional information is programmed with reference to a cutting tool centerline, or with reference to a cutting tool of standard dimension, provision being made for correcting such dimensional information by means of a position offset facility coupled to the numerical control so that dimensional information is modified in a sense to provide an indication of a desired position that accommodates a specific cutting tool dimension or other offset requirement, circulating register means being provided for circulating data with respect to a plurality of axes, and common arithmetic circuitry serving to process the data for the respective axes as the data circulates from the circulating register means through the common arithmetic circuitry.
摘要:
A numerically controlled positioning system for positioning a movable member, employing serial signal processing circuits having circulating registers for receiving discrete input signals representative of a desired position of the member and for receiving feedback signals of actual position of said member, in which, arithmetic combinations of the input signals, compensated as required for position offset, and the feedback signals, provide control signals for positioning the member.
