Method of measuring by coordinate measuring instrument and coordinate measuring instrument
First Claim
1. A method of measuring by a coordinate measuring instrument including a moving mechanism for moving a decting element in at least one of a two- and a tri-dimensional direction to bring same into contact with a work to be measured rested on a mount, a displacement detector for detecting a displacement value of said detecting element and a data processing unit for processing an output signal from said displacment detector in a predetermined manner to seek dimensions and the like of said work, comprising:
- moving said detecting element independent of a main body of a measuring instrument by said moving mechanism in accordance with a measuring step program including a plurality of steps preset in said data processing unit, while, a moving path of a robot mechanism is stored by a robot operating command unit;
operating said robot mechanism during a measured data fetch process to bring said detecting element into contact with said work in accordance with moving path data stored in said robot operating command unit in response to a step exciting command of said measuring step program, and simultaneously, for fetching an output signal of said displacement detector into said data processing unit; and
calculating dimensions and the like of said work during a measured value calculating process on the basis of the measured data fetched during said measured data fetch process and giving a succeeding step exciting command to said robot operating command unit upon completion of the calculation;
whereby said measured data fetch process and said measured data calculating process are repeated automatically over all the steps of said measuring step program.

Abstract
This invention relates to a method of measuring by a coordinate measuring instrument and the coordinate measuring instrument, wherein a probe to be brought into abutting contact with a work to be measured is moved in two- or tri-dimensional direction by a robot mechanism provided independently of a main body of measuring instrument. A moving path of the robot mechanism is preset, and, when a command to carry out a predetermined measuring program is given from a data processing unit, the robot mechanism is moved in accordance with the moving path, and a measured result is calculated to seek a dimension of the work, on the basis of measured data given through an abutting contact between the probe and the work.
