1.Product (system) design + tolerance
1) Function-oriented design: overall layout and component stacking.
2) DFA for the design of the assembly structure of the whole machine
3) Tolerance processing of design features such as guidance, positioning, fixing, connection, etc.
4) Introduction to tolerances** and dimensional chains.
2.Tolerance Basics and Applications
1) Size independence: correlation coefficient check.
2) Tolerance zone and tolerance grade.
3) Selection of mating type and grade.
4) Limit and Probabilistic Algorithms and Monte Carlo Simulations.
5) Size chain calculation (adding, decreasing, closing).
6) **Chain process capability CPK+ tolerance analysis.
3.Tolerance analysis tools
1) Dimension Chain Calculation Table (Excel) application.
2) Size chain Monte Carlo simulation (excel + crystal ball) application.
3) Size chain Monte Carlo simulation (minitab) application.
4) Cetol (Creo, SOLIDWORKS) dimension chain analysis software.
4.Part manufacturing process + tolerance
1) Mold misalignment and Class A and Class B tolerances.
2) Accuracy: size, position, shape and surface roughness.
3) Deformation: elastic recovery, insufficient rigidity of parts, shrinkage and expansion of materials.
5.Process benchmarks and design benchmarks
1) Introduction to part process benchmarks.
2) Fake scrap: the measurement benchmark and the design benchmark are inconsistent.
3) The processing benchmark and the design benchmark are inconsistent.
6.Fixtures + tolerances
1) Scope, definition, purpose, function and use of the fixture.
2) The design principle of the fixture.
3) The principle of tolerance distribution of inspection fixtures.
4) Inspection fixture design requirements.
