Abstract

Computer technology development has an impact on manufacturing technology development. CNC Lathe machine is a combination of computer technology and mechanical technology. This technology produces precision manufacturing products and fast processing times. Computer Numerical Control (CNC) is a machine controlled using a computer program to simplify the machine work process and make product results more uniform and acurates. A researcher makes this CNC Lathe machine from the Department of Mechanical Engineering Tanjungpura University Pontianak. It is named Small CNC Lathe machine with specifications, two axes (X and Z), and it has small dimensions to make it easier to move. This Small CNC Lathe Machine uses a spindle motor of 1 HP, 1500 rpm and a torque of 3.5 Nm, to move the X and Z axes using two stepper motors with a torque of 0.76 Nm for the X-axis and 1.2 Nm for the Z-axis. It has a motion limit of 215 mm for the X-axis and 75 mm for the Z-axis. This research was conducted to obtain the accuracy and error of the dimensional product made in this machine. The results of 16 workpieces with four different types of programs ware the average error percentage rate of 1.840%, so that it has an accuracy level of 98.160% for the X-axis and the average error percentage rate of 0,396% so that it has an accuracy level of 99.604% for Z-axis.
