Abstract

This thesis contains the report of how to build the mini CNC milling machine with the low cost compared to other machine that usually used in industry. This machine will be tested in term of accuracy and performance by doing some experiments. Most of the material that used to build this machine is Aluminum 6020 Alloy. Computer Numerical Control (CNC) machining is a process used in the manufacturing sector that involves the use of computers to control machine tools without direct human assistance. Tools that can be controlled in this manner include lathes, mills, routers, and grinders. CNC is a very broad term that encompasses a variety of types of machines all with different sizes, shapes, and functions. In modern CNC systems, mostly component design is highly automated using Computer Aided Design (CAM) programs but for this mini CNC milling machine, it is a simple and use basic CNC machine operation by using Mach3 software. There have some part that uses such as water cooled spindle with power 2.2 kilowatt, ball screw bearing, stepper motor, bearing, rail bearing, and some electronics parts. Some machining process are involves such as drilling, milling, cutting, facing, and others. This study focuses more on the how to build a mini CNC milling machine where this machine are very own, fully functional, easy to maintain and inexpensive. This machine also can cut, carves, engraves and drills any material depends on machine specifications that are build.
