Intro Flashcards
1
Q
Fixture
A
Contains jigs. Set blocks and feeler gauges are used to reference the cutter to workpiece
2
Q
Objective of tooling design
A
Easy to operate Reduce costs Improve quality Increase production rates Foolproof operations Increase tool life safety
3
Q
Jig
A
Device supports, locates, holds or placed on a part. Guides the cutting tool by utilizing a bushing
4
Q
Permanent work holders
A
High volume, possibly automated. Increased complexity (but not always)
5
Q

A
Built from components
6
Q
General purpose work holders
A
Generic (machine vise)
7
Q
Operation considerations
A
Type of operation Cutting force directions Grouping of operations Sequence Inspection requirements
8
Q
Equipment considerations
A
Machine tool specs Cutting tools Equipment availability Space required Storage requirements
9
Q
Initial tooling cost
A
= labor cost to make each of it + design cost
10
Q
Cost/part manufactured
A
=. Run cost + (set up / lot size). +( initial tooling cost / total quality over tooling life)
