2 Clarifications GCA 1 due Friday, 8 th Feb CAD 1 due Friday, 8 th Feb check the schedule for other assignments

3 CAD clarifications In ProE don’t worry about putting dimensions on 3D model For GCA 1 you will need Reference planes

4 Tutorial Tuesday, Thursday fill FDA 1 Lab (seat 52 students) Then MC 10 lab (seats 20 students)

5 Questions about Assignments

6 Lecture Outline Manufacturing considerations Review of machine tool lab Creating models using drill charts Examples of parts and how to make them Discussion of specific models

7 Manufacturing considerations Making sure that the Technician has no questions about how to make your model Tolerance (because machining is never 100% accurate) Machining process used Stock you will use (standard dimensions) Tools you will use
