Basic information of computer gong processing
1. When you enter the workshop for practice, you should wear work clothes, tie the big cuff tightly, and tie the shirt into the pants. Female students should wear safety helmets and incorporate braids into the helmets. Sandals, slippers, high heels, vests, skirts and scarves are not allowed to enter the workshop. Note: it is not allowed to operate the machine tool with gloves;
2. Be careful not to move or damage the warning signs installed on the machine tool;
3. Pay attention not to place obstacles around the machine tool, and the working space should be large enough;
4. If two or more people need to complete a certain work together, they should pay attention to the coordination and consistency between each other;
5. Compressed air is not allowed to clean the machine tool, electrical cabinet and NC unit;
6. The internship shall be conducted on the designated machine tool and computer. Without permission, other machine tools, tools or electrical switches shall not move randomly;
Preparations for computer gong processing
1. Before operation, you must be familiar with the general performance, structure, transmission principle and control program of CNC milling machine, and master the function and operation program of each operation button and indicator light. Do not operate and adjust the machine tool until you understand the whole operation process.
2. Before starting the machine tool, check whether the electrical control system of the machine tool is normal, whether the lubrication system is unblocked, whether the oil quality is good, and add enough lubricating oil according to the specified requirements, whether the operating handles are correct, whether the workpiece, fixture and cutter are firmly clamped, and whether the coolant is sufficient. Then start the idle car for 3-5 minutes, check whether the transmission parts are normal, and confirm that there is no fault After that, it can be used normally.
3. After the completion of the program debugging, it must be approved by the instructor before the step-by-step operation, and skip step execution is not allowed. Without the permission of the instructor, operate without permission or in violation of regulations. If the result is zero, the accident will be punished according to relevant regulations and the corresponding loss will be compensated
4. Before machining parts, it is necessary to strictly check whether the original point of the machine tool and the data of the cutting tool are normal and carry out the simulation operation without cutting path.
Precautions for computer gong processing
1. When processing parts, the protective door must be closed, and it is not allowed to stretch the head and hand into the protective door, and it is not allowed to open the protective door during processing;
2. During the processing, the operator shall not leave the machine tool without permission, and shall keep a high concentration of ideas and observe the operation state of the machine tool. In case of any abnormal phenomenon or accident, the program operation shall be terminated immediately, the power supply shall be cut off and the instructor shall be informed in time, and other operations are not allowed;
3. It is strictly prohibited to pat the control panel and touch the display screen. It is forbidden to knock the workbench, dividing head, clamp and guide rail;
4. It is forbidden to open the control cabinet of CNC system for viewing and touching without permission;
5. The operator shall not change the internal parameters of the machine tool at will. Students are not allowed to call or modify other programs not compiled by themselves;
6. On the machine tool control microcomputer, no other operation is allowed except for program operation and transmission and program copy;
7、 CNC milling machine belongs to large precision equipment. Except for the tools and workpieces placed on the workbench, it is strictly prohibited to stack any tools, clamps, blades, measuring tools, workpieces and other sundries on the machine tool;
8. It is forbidden to touch the tip of the knife and the iron scraps by hand. The iron scraps must be cleaned with an iron hook or a brush;
9. Do not touch the rotating spindle, workpiece or other moving parts by hand or any other means;
10. It is forbidden to measure the workpiece and change the speed manually in the process of processing, not to wipe the workpiece with cotton thread or clean the machine tool;
11. No trial operation;
12. When using the hand wheel or fast moving mode to move the position of each axis, be sure to see clearly the signs of “, -” in each direction of X, y, Z axis of the machine tool before moving. When moving, first turn the hand wheel slowly to observe whether the moving direction of the machine tool is correct before speeding up the moving speed;
13. When it is necessary to suspend the measurement of workpiece size during the operation of the program, the measurement can only be carried out after the machine tool stops completely and the spindle stops running, so as to avoid personal accidents;
14. If the machine tool is not used for several days, the NC and CRT parts shall be electrified for 2-3 hours every other day.
15. When the machine is shut down, it can only be shut down after the spindle stops for 3 minutes.
