Volumetric Error Measurement and Calibration of Coordinate Measuring Machines Using a Ball-bar Artifact

Ball-Bar Artifact를 이용한 CMM의 공간 오차 측정 및 분석

Volumetric error measurement and calibration of a coordinate measuring machine are studied by using a Ball-Bar artifact. Examples of the Ball-Bar design are shown using inbar materials and precision steel balls. Also, for the uncertainty error using the Ball-Bar is discussed. Method of Ball-Bar artifact and the analysis of the error vectors are proposed. Using the Ball-Bar data, we studied the method of volumetric errors ana]ysis of a coordinate measuring machine.
