Abstract

Abstract A numerical control equipment comprises control units (2) for applying to a drive motor (10), for driving a table (7) on which an object (8) under measurement is placed, a movement instruction for moving the object (8) to a theoretical position, a position register (4) for receiving a detection signal outputted by a position sensor (11) adapted to detect the position of the table (7), memory units (3) for storing instruction data separately according to functions and uses, and a measuring head (16) for measuring the difference between the stop position of the object (8) and a reference position simultaneously with positioning of the object (8) to the theoretical position, wherein the control units (2) operate a measurement value provided by the measuring head (16) and a register value of the position register (4) and rewrite the contents of addresses provided separately according to functions and uses in the memory units (3) with an operated value as a measurement result.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 163 words
A numerical control equipment, comprising: control units (2) for applying to a drive motor (10), for driving a table (7) on which an object (8) under measurement is placed, a movement instruction for moving said object (8) to a theoretical position; a position register (4) for receiving a detection signal outputted by a position sensor (11, 12, 13) adapted to detect the position of said table; memory units (3) for storing instruction data separately according to functions and uses; and a measuring head (16) for measuring the difference between the stop position of said object (8) and a reference position simultaneously with positioning of said object (8) to said theoretical position, wherein said control units (2) operate a measurement value provided by said measuring head (16) and a register value of said position register (11, 12, 13) and rewrites the contents of addresses provided separately according to functions and uses in said memory units (3) with an operated value as a measurement result.
Claim 2
Dependent Claim 163 words
A numerical control equipment, comprising: control units (2) for applying to a drive motor (10), for driving a table (7) on which an object (8) under measurement is placed, a movement instruction for moving said object (8) to a theoretical position; a position register (4) for receiving a detection signal outputted by a position sensor (11, 12, 13) adapted to detect the position of said table; memory units (3) for storing instruction data separately according to functions and uses; and a measuring head (16) for measuring the difference between the stop position of said object (8) and a reference position simultaneously with positioning of said object (8) to said theoretical position, wherein said control units (2) operate a measurement value provided by said measuring head (16) and a register value of said position register (11, 12, 13) and rewrites the contents of addresses provided separately according to functions and uses in said memory units (3) with an operated value as a measurement result.
