- Safety glasses
- Closed-toe shoes
- Hearing protection
- Tight fitting clothing.
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.
