Jig & Fixture Design


Purpose of Tool design

Unit1


Purpose of Tool Design

Tool design: the process of designing and developing the tools, methods, and techniques necessary to improve manufacturing efficiency and productivity


Purpose of Tool Design

Tool design objectives;

  • Provide simple, easy operating tools for maximum efficiency

  • Produce with lowest possible cost

  • Produce part with high quality


Purpose of Tool Design

Tool design objectives;

  • Increase production rate

  • Foolproof

  • Adequate tool life

  • Safety


Purpose of Tool Design

Tool Design in MFG.

  • Manufacturing for global competitiveness required the success of concurrent engineering


Tool Design in MFG.

Planning the Design

Manage information resources

  • Part Drawings

  • Production Plan

  • Alternatives


Tool Design in MFG.Planning the Design

Part Drawings: complete understanding of the part;

  • Overall size and shape

  • Condition of the material

  • Type of operation

  • Degree of accuracy

  • Number of producing

  • Locating surfaces


Tool Design in MFG.Planning the Design

Production Plan: itemized list of mfg operations;

  • Type and size of m/c tool

  • Type and size of cutters

  • Sequence of operations

  • Previous operations performed


Tool Design in MFG.Planning the Design

Alternatives: ensure the optimize method is chosen;

  • Should special tool be used?

  • Should multiple or single spindle m/c be used?

  • Should the tool be single or multi-purpose used?

  • What type of gauge be used?

  • Will the savings justify the cost of the tool?
