Abstract

Abstract A machine tool control system in which a programmable controller operates a machine to carry out a plurality of programmable functions. The controller includes a plurality of processor means, a first one of the processor means capable of pre-processing and forwarding control information to a second of said processor means, wherein said second processor means provides control information to control machine movement. Advantageously, the second processor means operates on a periodic time based interrupt method which greatly increases the accuracy of the machine.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 104 words
A programmable controller for operating a machine having a controllable X-axis function and a controllable Y-axis function to allow the machine to carry out a plurality of programmable functions, which controller comprises: a plurality of processor means wherein a first processor means pre-processes incoming data and forwards pre-processed data including velocity and acceleration data present in multiple forms and control information to one or more second processor means which provides control information to control machine movement; means included within said second processor means for providing a periodic time-based interrupt; and means responsive to said time-based interrupt for controlling said X-axis and said Y-axis functions.
Claim 2
Dependent Claim 104 words
A programmable controller for operating a machine having a controllable X-axis function and a controllable Y-axis function to allow the machine to carry out a plurality of programmable functions, which controller comprises: a plurality of processor means wherein a first processor means pre-processes incoming data and forwards pre-processed data including velocity and acceleration data present in multiple forms and control information to one or more second processor means which provides control information to control machine movement; means included within said second processor means for providing a periodic time-based interrupt; and means responsive to said time-based interrupt for controlling said X-axis and said Y-axis functions.
Claim 3
Dependent Claim 15 words
A programmable controller in accordance with claim 1, wherein acceleration is controlled by multiple additions.
Claim 4
Dependent Claim 15 words
A programmable controller in accordance with claim 1, wherein more than two axis are controlled.
