The definition and advantages and disadvantages of milling and reverse milling in milling machine processing
When the knife just contact with the workpiece, the cutting thickness is zero, only when the knife teeth in the former knife teeth left on the cutting surface over a distance, cutting thickness reaches a certain value, the tooth was really started cutting.
1. When milling, the cutting thickness of each knife is changed from small to large.
The milling speed is the same as the direction of rotation of the workpiece and the direction of rotation of the tool is the same, and the reverse milling is the opposite. The roughness of the milling process is high, which is suitable for finishing, but it can not be ruled out.
The reverse milling makes the cutting thickness gradually change from large to small, and the sliding distance of the tooth on the cutting surface is also small
