Heavy machining includes any work done on mills and lathes (manual mill, ProtoTRAK Mill, Haas Mini-Mill, Fadal VMC, manual lathe, Haas TL-1 CNC lathe). Work requiring heavy machines will require proper engineering drawings (with a properly formatted title block), followed by approval by shop staff, which is reflected on the wiki Heavy Work Permit Approval page.
If you plan on using light machines (drill press, band saw, sander, grinder) in conjunction with your heavy machining, a light machining work permit does NOT need to be filled out.
Heavy work permits will be approved Monday thru Friday ONLY. Requests submitted after 12PM on Friday will not be approved until Monday.
Your engineering drawing must contain a properly formatted title block.
The form of the subject line should be:
LAST NAME, FIRST NAME, MM/DD/YY, PML Work Permit Engineering Drawing
Failure to comply with these instructions will result in a delay in processing your work request.
