The CNC lathe operation panel is an important component of the CNC machine tool. It is a tool for the operator to interact with the CNC machine tool (system). It can be mainly divided into power control area, system control panel and machine tool control panel.
1. Power control area:
(1) System On: Turn on the system power.
(2) System Off: Turn off the system power.
(3) Program protection switch: open and close the program input function.
(4) Emergency stop knob: This button is used when the machine tool needs to stop urgently in case of danger or emergency during processing, or when the machine tool processing is terminated and the power is cut off. (Note: The emergency stop knob should be pressed before power on and off to reduce the electrical shock of the equipment.)
2. The CNC system panel mainly realizes man-machine dialogue in the process of program editing and debugging, tool setting parameter input, real-time monitoring of the current processing status of the machine tool, and modification of machine tool maintenance parameters.
PESET reset key: This key can be used when the current state is released, the processing program is reset, and the machine tool is stopped in an emergency.
PROC program key: In the editing mode, operations such as editing, modifying, searching and deleting can be performed.
OFS/SET tool offset key: Combined with other keys, it can set the workpiece coordinate system, and can perform tool nose radius and wear correction operations.
POS position key: Display the machine tool coordinates, absolute coordinates, incremental coordinate values of each coordinate axis and the axis distance specification of each coordinate during program execution.
CSTM/GPPH graphic display key: Combined with relevant keys, you can perform simulation processing on the display and observe the tool running track, while the machine tool does not perform actual processing.
After the parts are programmed and the tool is set, trial cutting and debugging are required, in order to prevent errors in the program and tool setting errors, resulting in collision accidents.
We should carry out the simulation processing of empty stroke first, and in the coordinate system of the CNC lathe, the overall translation of the tool to the right is 2-3 times the total length of the part; Parts are processed. After the first part is processed, self-inspection is performed first to confirm that it is qualified, and then a full-time inspection is carried out. After the full-time inspection confirms that it is qualified, it means that the debugging is over.
First rough machining, remove the excess material of the workpiece, and then finish machining; avoid vibration during processing; avoid thermal denaturation of the workpiece during processing, there are many reasons for the vibration, which may be due to excessive load; it may be CNC lathe and The resonance of the workpiece, or it may be caused by the lack of rigidity of the machine tool, or it may be caused by the passivation of the tool. We can reduce the vibration by the following methods: reduce the lateral feed and processing depth, and check whether the workpiece is firmly clamped. Increase or decrease the rotation speed of the tool to reduce the resonance. In addition, check whether it is necessary to replace the new tool.
