Programming of Element Part Drive Centralizer Using CNC (Computer Numerical Control) Milling Machine 3 Axis Type Haas

Abstract

This research aims to program the manufacturing process of a drive centralizer part using a 3-axis CNC milling machine as a solution to the dependency on imported drive centralizer parts while facilitating the manufacturing of complex parts thus requiring a high level of precision in its production process. The method used in this study is a quantitative approach, starting with manual measurements using a caliper to obtain accurate part dimensions, 3D design using CAD/CAM software, creation of G-code and M-code programs, toolpath simulation, and implementation on a 3-axis CNC milling machine. The material used for manufacturing the part is brass (CuZn) due to its corrosion resistance and ease of machining. Machining parameters were determined based on CNC machining standards, including cutting speed, feed rate, and spindle speed, to obtain optimal machinin results. The results show that the drive centralizer part design can be accurately created using CAD/CAM software, and the toolpath simulation runs correctly without errors, while the machining process using the 3-axis CNC milling machine produces parts with high accuracy and precision. This programming and part manufacturing process can also serve as CNC job sheet teaching material for students. By implementing this CNC programming, companies in the mining sector can obtain drive centralizer parts with more efficient cost and production time compared to importing parts from abroad.
