Many difficult-to-cut materials, such as cemented carbide, hard and fragile materials, composite materials, are widely used in these areas.
But some materials, such as aluminium-carborundum, engineering ceramics, etc, can be processed difficultly by traditional machining because the hardness of these materials is almost close to the diamond.
Against this backdrop, people begin to study how to settle the problem of difficult-to-cut materials by other means.
