When using a standard hand file to deburr and shape the edge of a metal workpiece clamped in a vise, what is the correct stroke technique to ensure efficient cutting and prevent premature tool wear?
- AApply firm, continuous downward pressure during both the forward push stroke and the backward return stroke
- Apply downward cutting pressure only on the forward push stroke, and relieve pressure or lift the tool slightly on the return strokeCevap
- CApply heavy cutting pressure exclusively on the backward pull stroke while lifting the file completely on the forward stroke
- DMove the file in a rapid back-and-forth scrubbing motion with continuous downward pressure to maximize friction
Cevap
Apply downward cutting pressure only on the forward push stroke, and relieve pressure or lift the tool slightly on the return stroke.
Standard machinist hand files are manufactured with teeth that slant forward, away from the handle. As a result, the tool only cuts metal on the forward push stroke. Relieving downward pressure or lifting the file slightly on the return stroke prevents the delicate cutting edges from dragging backward against the hard workpiece, significantly extending tool life and maintaining cutting efficiency.
