Machining – a type of cavity treatment involving the removal of individual layers of material and turning it into chips. Machining is divided into chip machining and abrasive machining. Chip machining is carried out with tools with a fixed geometry and number of blades, and the resulting chips have a specific shape, which on other factors such as material, feed, cutting speed, cutting temperature, etc. However, abrasive machining is characterized by very fine blades with an indefinite number and geometry, the product being chips in the form of small particles also of unsteady geometry.
Depending on the accuracy of machining we distinguish:
Medium accurate machining,
Very accurate (finishing) machining.
