Four Step Check for turning on the lathe or mill

- Ensure the machine is in the proper speed range. - Check that there is clearance around the tool - Verify that the rotation of the chuck/spindle is counterclockwise - Lower the chuck guard/chip shield

Vertical Bandsaw Safety

1. Always wear safety glasses 2. NEVER wear gloves, since they can be caught by the moving blade and pull your hand into the cutting zone. 3. Set the upper blade guide with 1/4" of the workpiece. 4. NEVER place your hands within the plane of the blade. Use a push block for small work. 5. Do not push the workpiece into the blade with enough force that the blade chatters. Slow down and find a more rigid manner to support or clamp the piece to the machine. 6. Never cut materials that might be hardened, such as tool steel, files, or stainless steel. 7. If the blade breaks, shut off the power, stand clear until the machine stops and inform the laboratory staff so a replacement blade can be promptly installed.

(Marvel) Vertical Power Feed Bandsaw Safety

1. Always wear safety glasses when operating the bandsaw. 2. Never wear gloves as they could get caught on the moving teeth and pull your hands into the moving blade, causing a severe injury. 3. The upper blade guide should be set to within ¼ inch of the workpiece. Adjust the guard with the machine turned off and never loosen the adjustment handle more than ¼ turn. 4. Do not push the blade into the workpiece hard enough to cause the machine to chatter; slowdown and/or find a more rigid manner in which to clamp the work in the saw. 5. Always adjust the speed of the bandsaw while the machine is running. Never adjust the speed with the machine turned off. Do not run the band saw at a higher speed than recommended for the material being cut. There is a table on the saw with recommended saw speeds for various materials. 6. Make sure the workpiece is clamped securely before turning on the saw. Failure to do so will result in the workpiece dislodging from the vise and breaking the saw blade. 7. Always bring the blade into contact with the material before engaging the automatic power feed. The proper procedure is as follows: (1) firmly clamp the workpiece in the vise;(2) turn on the saw so the blade is rotating; (3) adjust the coolant if necessary; (4) gently bring the moveable saw blade into light contact with the workpiece by rotating the manual feed wheel; (5) engage the automatic feed lever; (6) disengage the automatic feed after the workpiece is cut but before the blade passes the remaining stock in the vise; (7) slowly retract the blade to its original (starting) position; (8) turn off the saw. 8. Never cut materials that might be hardened, such as tool steel, files, hardened guide ways, stainless steel, etc. Any material than cannot be cut easily with a standard hand file should never be cut in a bandsaw; use an abrasive cutoff saw instead or ask an instructor. 9. If the band breaks, immediately shut off the power and stand clear until the machine has stopped. Promptly inform the laboratory staff so a replacement blade can be installed. 10. Never leave the machine unattended when the saw is running.

Five Step Check for installing and removing tools on the mill

1. Make sure the power is off and the spindle has stopped rotating. 2. Always position one of the plastic table covers below the spindle before changing tools to ensure the vise is out of the way of tools which are accidentally dropped. 3. Release the 1.5′′ long quill clamp on the right side of the quill housing by rotating the lever counter-clockwise using the palm or your right hand. 4. Raise the spindle to the uppermost position using the quill handle on the right side. 5. Raise the silver spindle lock to the highest position by pressing the round button,raising it to the top of its travel and releasing the button. Ensure the spindle lock is all the way up by threading it finger-tight against the black quill stop.

Maximum depth of cut in DML is...

100 thou. Anything between 100 and 20 thou is a roughing pass. Cutting oil is always necessary for roughing passes.

Finishing pass

Any cut below 20 thou.
