Which of the following is an example of a net shape or near net shape process?
Metal casting
Which of the following is NOT a benefit of using net shape or near net shape processes?

What is the difference between allowance and tolerance in engineered components?
Allowance is the permissible deviation from a desired dimension, while tolerance is the intentional difference between the dimensions of two mating parts.
Which of the following is NOT a benefit of using net shape or near net shape processes?
More energy and material waste

The International Tolerance Grade defined in ISO 286.
What is a potential problem with adopting net shape processes for large components?
Problems with repair or replacement
What is a potential issue with adopting net shape processes for large components?
Problems with repair or replacement
What is the relationship between the IT grade and tolerance in industrial processes?
The larger the ITG, the looser the tolerance

Study Notes
- The five "M's" of manufacturing are money, manpower, machines, materials, and measurement.
- Metal shaping has several subdivisions and typical shaping processes.
- Allowance and tolerance must be specified in engineered components to obtain the desired fit between mating parts.
- Allowance is the intentional difference between the dimensions of two mating parts, while tolerance is the permissible deviation from a desired dimension.
- The IT grade refers to the International Tolerance Grade of an industrial process defined in ISO 286.
- The larger the ITG, the looser the tolerance.
- An industrial process has an IT Grade associated with it, indicating how precise it is.
- Typical surface roughness values include Ra, RMS, CLA, Rt, and N.
- Ra is the average roughness value in micro-meters or micro-inches.
- Cut-off length is the length required for a sample.
