Chip thickness and milling face mill main angle

Chip thickness and milling face mill main angle. The main angle is the angle between the blades of the main cutting edge and the workpiece surface, there are 45 degrees, a 90 degree angle and a circular blade. The direction of change of the cutting force change a lot as the main angle different: the main angle of 90 degrees the cutter mainly produces radial force role in the direction of feed, which means that the machined surface will not to put too much pressure, a weaker structure of the workpiece for milling is more reliable.

Main angle of the cutter 45 degrees is roughly equal to the radial cutting force and axial pressure generated by a more balanced machine power requirements are relatively low, especially for milling produces chipping chip short chipping materials workpiece.diamond discs

The main angle of the circular blade cutter means continuously changes from 0 degrees to 90 degrees, which is mainly dependent on the cutting depth. This blade cutting edge strength is very high, and the the chips generated direction along the long cutting edge is relatively thin, so suitable for a large amount of feed. The cutting force in the direction radially along the blade in the changing, and the pressure generated in the process will depend on the depth of cut. The advantage of the development of modern blade geometry trough with smooth cutting effect of the circular blade machine power demand is low, good stability. Today, it is no longer an effective coarse milling, have a wide range of applications in the face milling and endmilling,.granite core bits

There are two ways with respect to the feed direction of the workpiece and the milling cutter rotating direction. The first is a cis milling, the direction of rotation of the milling cutter and cutting the feed direction is the same, and the cutting cutter bite the workpiece and cut out of the last chip. Second is cut milling cutter rotation direction and the cutting feed direction is opposite, the cutter prior to start cutting on the workpiece must slip period zero thickness of the cutting start to the cutting end of the cutting thickness maximum.
