Material is removed by a file during___________________?
Show answer Hide answer
Answer: B. forward stroke
Explanation
Files feature rows of sharp teeth angled in a single direction. Material is sheared away only when the file is pushed forward. Lifting or dragging the file back removes no metal and dulls teeth. Hand files are essential benchwork tools used for shaping metal components. Teeth cut on the forward stroke prevent premature wear of the tool. Proper filing technique requires consistent downward pressure on forward strokes.
Machinists deburr sharp metal edges using hand files in workshops. Toolmakers fit mechanical components together by manual filing methods. Maintenance technicians rely on files for minor adjustments during repairs. Option A is incorrect because return strokes do not feature cutting teeth. Option C is wrong because pulling the file backward causes tooth damage. Option D is false because files definitely cut on the forward stroke.
