  • Work to ensure the safety of yourself and others
  • Any injuries must be reported immediately via an injury incident report

Training & Access - If you have little to moderate experience in a shop environment, currently the only way for you to gain access is through successful completion of MEAM201 (MEAM150 prior to June 2011), which includes the necessary training to utilize a manual mill, manual lathe, band saw, and hybrid CNC mill in a safe and efficient manner. Upon completion you will be assigned a shop access level and entered into the shop database.

Once obtained, access is valid for the remainder of the semester in which the course was taken. To have access reinstated in a subsequent semester, you must attend an all-hands safety briefing at the beginning of each term where we will refresh safety protocol and cover any changes or modifications to the equipment or shop policies (you will receive an email announcement near the start of each term to let you know when and where this will take place).

Preparation - If your project will require use of a mill or lathe, you must complete an electronic MACHINING WORK PERMIT. Once you have completed the form, you MUST submit your fully defined engineering drawing to MEAMshop@gmail.com. This form is required for all work done in the MEAM Precision Machining Laboratory (Towne 169). All work permits will need to be approved by the shop staff, Monday thru Friday ONLY. Requests submitted after 12PM on Friday will not be approved until Monday. The approval spreadsheet will reflect when your job has been approved.

Working in the Shop - Upon entry to Towne 169, you will present your PennCard to the on-duty staff person, who will sign you in and confirm your access level (note that we will keep your PennCard while you are in the shop). If you are there to work on a permitted project, your permit will be retrieved, and you will be responsible for logging machine usage.

When you complete work on a particular machine, you will need to thoroughly clean up the space, and present your permit usage log for inspection and approval by the shop staff person or on-duty student worker.

Before you leave the shop, you be assigned a brief shop job after which your PennCard will be returned.
