¶ Checklist and Machine Use Procedures
It is important to follow strict of rules of personal conduct and etiquette in the shop. This will keep you and your peers safe and promote a hospitable and professional environment:
- Know where your hands are at all times.
- No horseplay or practical jokes are allowed in the shop.
- Do not interrupt someone working at the machine. This could cause them to make a mistake.
- Clean up after yourself. Leave the machine and surrounding area at least as clean as you found it.
- Always put tools and equipment where you found them.
- Wear ANSI approved safety glasses. You must wear safety glasses at all times in the shop, not just when at the machine.
- If machining operations are loud, use hearing protection.
- Closed toed shoes only. Leather shoes are best. Steel toe shoes are not necessary unless handling heavy objects that would crush regular shoes.
- Do not wear long sleeve shirts because these could get caught in equipment. Wear short sleeves or T‐shirts.
- Do not wear short pants. Wear sturdy long pants like blue jeans or work pants.
- Long hair should be tied back or under a hat to prevent it being caught in the machine spindle.
- Never wear gloves as they can be caught in the machine. Latex gloves are acceptable.
- Never use any equipment which you have not been trained to operate by a qualified person.
- Use caution when handling cutting tools. They are very sharp. Never handle a tool by its cutting flutes.
- Never start or jog the machine until you have checked that the work area is clear.
- Never push the start button on the machine unless you are certain your setup is capable of safely holding the part against all cutting forces during machining.
- Use caution when running a new program: especially at the start of program and after a tool change.
- Know where the emergency stop is on the machine and practice using it before you need it.
- Never run a machine alone or without other people within hearing distance.
- When working with someone else at the machine, clearly communicate who is running the machine.
- Never have one person touching the control while the other is working in the machine envelope.
- Never leave a running machine untended.
- Remain alert. Think safety in everything you do.
Use these extra precautions when running a CNC program for the first time:
- Use machine Rapid and Feed override controls to slow the machine down.
- A major cause of crashes is setting the tool or fixture offset incorrectly. Pay particular attention to moves at the start of program and immediately after a tool change as the tool moves towards the part.
- Remain at the machine with a hand on or near the emergency stop button.
- Stop machine motion at the first sign of trouble.
- Vacuum chips and dust.
- Return collets and bits.
- Clear workstation.
