When shaping and smoothing a metal workpiece using hand files, arrange the following file cut grades in order from the coarsest cut (most aggressive stock removal) to the finest cut (smoothest finish). Which sequence correctly arranges these file grades from coarsest to finest?

  1. 1Bastard cut
  2. 2Second cut
  3. 3Smooth cut
  4. 4Dead smooth cut

Cevap

Bastard cut → Second cut → Smooth cut → Dead smooth cut
Machinist files are graded by coarseness from coarsest to finest as: Bastard cut, Second cut, Smooth cut, and Dead smooth cut. Metalworking operations progress from the coarsest tooth pattern to remove bulk stock quickly, then step progressively through finer teeth to achieve a smooth final surface without leaving deep scratches.

Adım Adım Çözüm

1
Identify the file grade with the coarsest teeth for initial rough shaping.
Bastard cut file is placed first.
Coarse teeth remove excess material quickly without clogging immediately.
2
Select the medium grade used to bring the workpiece closer to final dimensions.
Second cut file is placed second.
Medium teeth smooth out the heavy tool marks left by the bastard file.
3
Select the fine grade used for standard finishing work.
Smooth cut file is placed third.
Fine teeth remove minor surface imperfections.
4
Select the finest grade for final finishing and polishing.
Dead smooth cut file is placed fourth.
Extremely fine teeth create an ultra-smooth, uniform surface finish.
