Working Steps of CNC Lathe

Working Steps of CNC Lathe
  1. Load the part program into the lathe if it is not already there. On newer machines, use a USB drive to transfer programs from a computer to the machine. With old machines, you may need to use a serial connection to the computer or even an 3.5-inch floppy disk.
  2. Load the workpiece into the lathe. Make sure the chuck or collet has a tight grip on the workpiece.
  3. Load the necessary tools into the lathe. The tools you will need for agiven program, as well as the turret slots in which they should be
    placed, will have been determined at the time the program was written.If you will be using a program you did not write, consult the programmer if you have any questions about which tools to use.
  4. Turn on the coolant pump and move the nozzle so the coolant stream is hitting the tip of the tool. Repeat this step for each tool.
  5. Set the tool offsets. Slowly bring each tool toward the toolsetter on the lathe until you hear a beep. Record the tool’s position in the tool
    offset screen under the appropriate tool number. Repeat this procedure to set the X and Z offsets for each tool. For some programs, you will also have to record the tip radius of certain cutting tools in the tool offset screen. The tip radius should be found either marked on the tool or in the documentation for the tool.
  6. Set the work offset. Rotate the turret to one of the cutting tools for which you have set the tool offset. Start the spindle and manually
    jog the cutter so that it faces off the end of the workpiece, leaving a smooth surface. Record the tool’s position under the Z axis work offset.
Specific procedures for performing these steps will vary substantially from one machine to another. Consult the user manual for your machine for specific instructions.>
Some colleges and technical schools offer courses in CNC technology. Such a course could be a help if you intend to pursue a job in the field of CNC programming or machining.
