Application should include using arithmetic, geometric, algebraic, and trigonometric operations when
- selecting and sequencing operations
- holding the work
- producing surfaces
- locating surfaces and center lines
- analyzing operations and sequences
- troubleshooting machine tools or cutting tools
- calculating speeds and feeds
- calculating operation times
- calculating dimensions from a blueprint
- factoring statistics required by control charts
- identifying the impact of a change of speed or feed
- calculating the volume of material stored
- using trade formulas to prepare a process plan
- performing benchwork and layout operations
- operating machine tools
- performing inspection and control functions
- solving for unknowns in right triangles
- analyzing parts for plane perpendicularity, Cartesian coordinates, concentricity, parallelism, straightness, flatness, circularity, and symmetry, with an accuracy required by the blueprint and industry standards.
