The basic process of CNC turning parts usually includes the following steps:
First, preparation
Analyze parts drawing and process plan:
According to the parts drawing, analyze the shape, size, material and accuracy requirements of the parts.
Develop NC turning process plan, including machining sequence, tool selection, cutting parameters, etc.
Write processing program:
Write NC turning program using specified code and program format.
The program should include the machining path of the part, tool movement instructions, cutting parameters, etc.
Input processor:
The written machining program is entered into the CNC unit through the input device.
You can use tape, disk, U disk and other carriers, or through serial communication and other ways to input programs.
Second, machine tool preparation
Boot and check:
Turn on the main power supply of the CNC lathe, start the CNC system and the machine tool.
Check the connection status of the pneumatic, hydraulic and other auxiliary equipment of the CNC lathe to ensure the normal operation of the machine.
Select a reference point:
CNC lathes need to establish the moving reference of each coordinate of the machine tool before machining parts, that is, select a fixed reference point.
Third, workpiece clamping and tool
Workpiece clamping:
Clamp the workpiece to the machine to ensure that the workpiece is firmly clamped and accurately positioned.
The clamping force should be moderate to avoid deformation or breakage of the workpiece.
Blade Set:
The tool used in the machining program is calibrated to determine the position of the tool in the machine coordinate system.
Enter the compensation value of the tool to ensure machining accuracy.
Fourth, program debugging and processing
Program debugging:
When the machine is locked, only the system is run to check the correctness of the program.
If you find a program error, you need to re-edit and enter the program.
Processing process:
When the program is started in automatic mode, the machine begins to process according to the program instructions.
In the machining process, the feed speed and cutting parameters can be adjusted to meet different processing needs.
Detection and feedback:
After machining, the parts are inspected to verify machining accuracy and surface quality.
If necessary, adjust and optimize the program or machining parameters based on the test results.
Fifth, finish up
Cleaning machine:
After the processing is completed, clean the chips, coolant and other debris on the machine tool to keep the machine clean.
Shutdown and recording:
Turn off the main power supply and the CNC system of the CNC lathe.
Record the relevant data in the machining process, such as cutting parameters, tool wear, etc., for subsequent reference.
In summary, the basic process of CNC turning parts covers a number of links from preparation to finishing work. Each link requires careful operation to ensure processing quality and efficiency.
