Manufacturing project process sheet assignment

A process sheet will be done for the machining of each of the two parts for the ice scraper. This is an individual assignment not a group effort. The process sheet will include the following; the feature that is to be machined, the machine that will be used, the tooling used, and the sequence of operations for each part.

A process sheet will include the feature being machined, the machine to be used, the tooling needed, and these items will be in a sequence of operations (such as turning, milling, drilling, tapping, etc...) that makes sense for the part being machined. Your starting material will be a piece of polycarbonate roughly 4 1/8” x 5” x 3/8”, and a piece of uhmw PVC 1.5” diameter by 6” long. Looking at the drawing or part files determine what feature needs to be made (sequence of operations), what machine it should be run on, and what tooling will be used. This should be done in a table format for each part.

The sequence of operations should include the order in which the part will be cut, whether the part needs to be repositioned in the same machine or placed in a different machine for the next operation. As an example, the ice scraper handle should probably be turned first in a lathe, before the slot or holes are put in a mill. It is not unusual for parts to need more than one machine to complete all the features.

Example of format for machining a 1-inch diameter cylinder 8 inches long.
