Chipping Tools
Chipping is a process of removing metal from a workpiece by means of a cutting instrument called a chisel and a striking tool called a hammer. Chipping is used when a large piece of metal has to be removed from a workpiece; this process is applied only when the workpiece cannot be machined. Chipping is used when it is necessary to cut off a piece of metal from sheet metal. Chipping of large parts is done on an anvil or in a bench vice. The workpiece to be tooled is fixed during the cutting process in the bench vice.
A chisel is a tool made of very hard steel, with a cutting edge at one end of the blade. This cutting edge is wedge-shaped. The work of the wedge depends mainly on its cutting angle. The cutting edge of the chisel should be sharpened to provide the best cutting quality, depending on the stock to be chipped. The harder the metal, the larger should be the cutting angle of the chisel and vice versa. An angle of about 70° is suitable for most work. There are different types of chisels such as flat chisels, cape chisels, etc.

Translate into Ukrainian upon the model:
The harder is the alloy, the better is the quality of the part made of it.
Що твердіший сплав, то краще якість деталі, що виготовлено з нього.
1. The better is the tool sharpened the quicker is stock removal.
2. The sharper is the chisel the quicker is chip removal.
3. The larger is the part to be chipped the longer is the process of chipping.
4. The sharper is the chisel the better is the quality of work.
5. The harder is the metal, the longer should be the cutting angle of the chisel.
6. The softer is the metal, the shorter should be the cutting angle of the chisel.
