Machine tool processing is a high-precision manufacturing process involving various equipment and techniques. To ensure processing quality, enhance production efficiency, and guarantee the safety of operators, the following points should be noted during the machine tool processing:

I. Preparations Before Operation

1. Equipment Inspection
Before starting the processing, a comprehensive inspection of the machine tool must be carried out, including:
- Checking whether all parts of the machine tool are intact, especially the key components such as the spindle, guide rails, and cutting tools.
- Checking whether the lubrication system is working properly to ensure adequate lubrication of all parts of the machine tool.
- Checking whether the electrical system is normal to avoid short circuits or leakage.
- Checking whether the cooling system is normal to ensure effective cooling during the processing.

2. Workpiece and Tool Preparation
- The workpiece must be securely fixed to prevent loosening or displacement during processing.
- The selection of tools should be based on the processing material and process requirements to ensure the sharpness and durability of the tools.
- When installing the tools, pay attention to the angle and position to ensure processing accuracy.

3. Program Inspection
- For CNC machines, it is essential to carefully inspect the processing program to ensure its accuracy.
- Conduct a simulation run to observe whether the processing path is reasonable and to avoid collisions or incorrect operations.

4. Safety Protection
- Operators must wear protective equipment properly, such as safety helmets, protective glasses, gloves, etc.
- Ensure that the safety protection devices of the machine tool (such as protective covers, emergency stop buttons, etc.) are in normal working condition.

II. Precautions during the processing

1. Operating Procedures
- Operate strictly in accordance with the operating procedures to avoid any violations.
- Keep a close eye on the machine tool's running condition during the processing and stop the machine immediately for inspection if any abnormality is detected.

2. Control of Cutting Parameters
- Select the cutting speed, feed rate and cutting depth reasonably based on the material of the workpiece and processing requirements.
- Avoid excessive cutting force that may cause damage to the machine tool or cutting tool.

3. Coolant Usage
- Use coolant reasonably during processing to prevent overheating of the workpiece and cutting tools.
- Regularly check the concentration and cleanliness of the coolant to ensure its cooling effect.

4. Tool Wear Monitoring
- During the Machining process, regularly check the wear condition of the tools and replace those that are severely worn in a timely manner.
- Avoid using worn tools for machining to prevent affecting the machining quality.

5. Workpiece Measurement and Adjustment
- During the processing, the workpiece should be measured regularly to ensure that the dimensional accuracy meets the requirements.
- Adjust the processing parameters or tool position in a timely manner based on the measurement results.

6. Prevention of Vibration and Noise
- During the processing, excessive vibration of the machine tool should be avoided to prevent affecting the processing accuracy.
- When abnormal noise is detected, the machine should be stopped immediately for inspection and troubleshooting.

III. Post-processing Work

1. Equipment Cleaning and Maintenance
- After processing, promptly remove the chips and coolant from the machine tool to keep it clean.
- Perform lubrication and maintenance on the machine tool to ensure it is in good condition.

2. Workpiece Inspection
- After processing is completed, conduct a comprehensive inspection of the workpiece to ensure that its dimensions, shape, and surface quality meet the requirements.
- Analyze the Non-conforming workpieces, identify the causes, and improve the processing techniques.

3. Record and Summarize
- Record key parameters and problems during the processing to facilitate subsequent analysis and improvement.
- Summarize processing experience, optimize processing techniques, and enhance production efficiency and quality.

IV. Safety Precautions

1. Operator Training
- Operators must undergo professional training to be familiar with the operation procedures and safety precautions of the machine tools.
- Regular safety education and skills training should be conducted to enhance the safety awareness and operation proficiency of the operators.

2. Emergency Handling
- In case of an emergency during processing, immediately press the emergency stop button to halt the machine tool's operation.
- Be familiar with the emergency handling procedures of the machine tool to ensure prompt response to unexpected situations.

3. Preventing Misoperation
- During processing, avoid accidentally touching operation buttons or switches to prevent equipment damage or personal injury.
- For CNC machines, operators should be familiar with the program's running logic to avoid accidents caused by program errors.

4. Equipment Maintenance
- Regularly maintain and service the machine tools to ensure they are in good condition.
- When equipment malfunctions are detected, promptly contact professional personnel for repair to prevent operation while faulty.

V. Environmental Protection and Energy Conservation

1. Waste material treatment
- Chips and waste materials generated during processing should be collected separately to avoid environmental pollution.
- Recyclable waste materials should be recycled and reused to reduce resource waste.

2. Energy-saving Measures
- Select processing parameters reasonably to reduce energy consumption.
- Optimize processing techniques to enhance production efficiency and lower energy consumption per unit product.
