Abstract
Abstract An automatic process control system in which a model of the process is prepared in the form of a two-dimensional pattern, coordinates of the pattern being defined by two parameters representing two kinds of information signals derived from the process, whereby the two information signals are converted to a single signal representing a spot in the pattern, and on the basis of the single signal a set of control signals are produced through appropriate signal processing means to be fed back to the process.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
110 words
A process control system for optimumly controlling factors relating to process speed using a patterned program and in response to parameters representing conditions of the process; said system comprising a pattern representing the desired relation between said parameters and the required control, means for detecting the conditions of the process and for producing information signals representing said parameters, pattern recognition means for receiving the information signals representing said parameters and producing a signal indicating the required control determined by the pattern, and a command generator for delivering command signals in response to the output signal of said pattern recognition means so as to control the factors relating to process speed.
Claim 2
Dependent Claim
110 words
A process control system for optimumly controlling factors relating to process speed using a patterned program and in response to parameters representing conditions of the process; said system comprising a pattern representing the desired relation between said parameters and the required control, means for detecting the conditions of the process and for producing information signals representing said parameters, pattern recognition means for receiving the information signals representing said parameters and producing a signal indicating the required control determined by the pattern, and a command generator for delivering command signals in response to the output signal of said pattern recognition means so as to control the factors relating to process speed.
Claim 3
Dependent Claim
61 words
A process control system according to claim 1, wherein said pattern is a two-dimensional pattern having a plurality of regions physically distinct from one another, and said pattern recognition means comprises means provided on said pattern for detecting the region in which said detecting means exists and means for moving said detecting means over said pattern in response to said information.
Claim 4
Dependent Claim
58 words
A process control system according to claim 1, wherein said plurality of regions comprises electrically conductive planes electrically isolated from one another, and said detecting means comprises an electric contacting unit which makes an electric conduction with a region of said pattern, and further, respective regions of said pattern are connected with respective counter-parts of said command generator.
Claim 5
Dependent Claim
20 words
A system as in claim 1 wherein said process is cutting and said parameters are cutting force and tool temperature.
