Engineering Practices: Material Processing

Separating & Machining

EP-MP-6

Engineering Performance Matrix

Separating/Machining include the processes that give an object a desired form by removing excess materials which includes knowledge related to basic machine operations of (a) drilling, (b) cutting, (c) milling, (d) turning, (e) grinding, and (f) shearing. This core concept is important to the practice of Material Processing as the related operations are the foundation for production and manufacturing of physical products. Furthermore, engineering professionals apply an understanding of these processes to inform their decisions when developing a design and performing the operations to remove undesired materials to achieve a desired form of a product.

Performance Goal for High School Learners

I can successfully use knowledge of Separating/Machining to inform my decisions when developing a design as well as to physically change the shapes of objects by removing excess material.
