Module 2 Objectives

- Be able to list at least 8 reasons to automate.
- Give at least 5 reasons why one should not automate.

**Tooling and Fixturing**

- Given labor, machine, and tooling costs, be able to calculate if capital expenditures for tooling are justified.

- Given a prismatic workpiece, be able to show fixturing locations using locating and supporting principles.
- Given a vertically rotational workpiece, be able to show fixturing locations using locating and supporting principles.
- Given a horizontally rotational workpiece, be able to show fixturing locations using locating and supporting principle.
- Given your experience with fixturing in the lab, what is the most important lesson learned about fixturing

**Milling Operations **

- Know the differences in different types of operations on the vertical mill: drilling, reaming, tapping, counterbore, slab milling, end milling, and profile milling.
- Given cutting speed and tool diamter, be able to calculate spindle rpm for drilling or milling.
- Given a feed and spindle rpm, be able to calculate feed rate for either a drilling or milling operation.
- Given a depth of cut, cutter diameter, feed rate and contour length, be able to calculate machining time for a milling operation.
- Given a width of cut, depth of cut, and feed rate, calculate the material removal rate for a milling operation.

**Turning Operations**

- Know the differences in different types of turning operations: facing, contouring, chamfering, and parting; why do you need to know these?
- Given cutting speed and tool diamter, be able to calculate spindle rpm for turning.
- Given a feed and spindle rpm, be able to calculate feed rate for turning.
- Given a feed rate and contour length, be able to calculate a machining time. .
- Given a depth of cut, feed, and spindle rpm, calculate the material removal rate for a turning operation.

**Process Planning **

- Given pertinent material, labor, and overhead costs, be able to determine whether a part should be made in house or bought from an external vendor.

**CNC Programming **

- Given a simple part and the G code primer, be able to write the G code necessary to mill the part.
- Given a simple part and an APT code for the part, be able to determine the missing element(s) needed to fully machine the part.
