On the forward stroke. You naturally push down as you push forward.
Yes, you can sharpen a file to improve its cutting ability by using a file card or a diamond file to remove any dull edges or burrs. This process helps to restore the file's sharpness and effectiveness in cutting materials.
Double cutting file
During the return stroke it does not remove any material, it is an idle stroke so to improve the cutting efficiency it will move faster during the return stroke. Pradip Kotak.
1) The cutting speed is constant almost throughout the stroke 2) The ram stroke reverses quickly with out any shock as the oil on either side of the piston provides a cushioning effect hence , vibrations are minimum 3) a number cutting speeds can be obtained and control is simpler 4) more strokes per minute can be obtained at a given cutting spee3d
answ2. This refers to the shape of the tiny cutting surfaces on the file.A smooth file has small teeth, and are continuous across the file face.A second cut file will have the simple cutting edges of a smooth file further divided by grooves at an angle to the first. This is your most common file.Beyond this you have coarse files, and bastard files, halfway between coarse and 2nd cut.
making changes
Cutting melamine cleanly has very little to do with the machine, and a lot to do with the blade. You want fine, sharp teeth, and you want the cutting stroke to move away from the surface you want to preserve.

The clogging of hand file teeth is commonly referred to as "file loading." This occurs when debris, such as metal shavings or other materials, accumulates in the teeth of the file, reducing its cutting efficiency. Proper cleaning techniques or using a file card can help remove this buildup and restore the file's effectiveness.
cutting and passing
Chalk is rubbed into a file before filing metal to reduce friction and prevent the metal shavings from clogging the file's teeth. This helps maintain the file's cutting efficiency and produces a smoother finish on the workpiece. Additionally, the chalk can help prevent rust on the file during use.
When working with a beating file, a common tool to use is a rasp or a file card. A rasp helps in shaping and smoothing the material, while a file card is used to clean the file's teeth, ensuring effective cutting. Additionally, a sturdy workbench or vice can provide stability while you work.
