Abstract

Nowadays, manufacturing industries are facing problems in determining or verifying the machine tool accuracy. In the manufacturing sector, the accuracy of parts is very important because from the finish part we can evaluate the accuracy of the machine that produces the particular part. One method that can be recommended is by specifying the machine tool accuracy by conducting performance test to the machine that is likely to be used. The performance test conducted should be based on certain standards to ensure the validity of the results. The performance test conducted uses a certain standard for machining center test which is International Standard Organization (ISO) 10791-2:2001 : Test Conditions for Machining Center ' Geometric that is a test for machines with vertical spindle or universal heads with vertical primary rotary axis ( vertical Z-axis)'. By referring to the standard, the accuracy of the machine can be determined by specifying the value of tolerance from the finish part produced. The standard test piece was machined by using a 3 axis machining center which specifies the eight critical parameter that includes in the standard which is straightness, parallelism, angularity, perpendicularity, circularity, concentricity, position, and cylindricity. In this project, a 3- axis vertical machining center is used to conduct the performance test. The standard test piece machined will be measured by using suitable metrology equipment at KUTKM laboratory to determine the tolerances of the eights critical parameter are within ISO tolerance. The machine can be classified as operating in the acceptable working conditions if the tolerance results are within the tolerances in the ISO 10791-2:2001.
