ENGR 0022 Study Guide - Midterm Guide: Hardenability, Soldering, Heat Treatment
Document Summary
Advantages of machining: applied to the vast majority of metals, wide shaping flexibility, good dimensional accuracy tolerances, good surface finish. Disadvantages of machining: volume of material removed is waste, time-consuming for large shaping / volume changes. Material removal rate for orthogonal machining and turning. Rmr (mm3/s) = v * f * d. D is depth of cut (mm) f is feed (mm) Rmr (mm3/s) = v * to * w. W is width of cutting tool (mm) to is depth of cut (mm) The four types of conventional machining and the relationship between feed direction, tool axis, and workpiece surface. Drilling: tool moves parallel to tool axis and feed is perpendicular to workpiece surface. Turning: tool moves perpendicular to the workpiece axis and feed is parallel to axis. Peripheral milling (left): tool is moved along workpiece surface and spins on axis parallel to work surface.
