Entering G-codes is the most important section while carrying out the operations, once the G-codes entered is wrong, not only the workpiece is damaged, but also the machine. With the explaination of the lab assistant, we are able to understand the process thoroughly. Through our observation, there are some differences between CNC milling machine and CNC lathe machine. In the CNC milling machine the workpiece is moving rather than the machine to complete the milling process whereas the workpiece of the CNC lathe machine does not move , the other parts of the machine is moving. There are some precautions to be taken in the lab. Ensured the side door of the CNC lathe machine is closed during the operation to prevent the chips from coming out. Besides that, makesure all cutting tools and workpice are hold tightly before operating the machine.Other than that, since the G codes will caused big difference in result, we should always ensured the correct tool data is entered into the CNC programme. Futhermore, CNC machine can only be control by skilled CNC machines operators as it is dangerous for first time user to control the CNC machine.
