optimization of milling

In the optimization of milling, milling cutter blade is another important factor, if at any time during the milling blade cut at the same time over a number of advantages, but also in the diamond cutting too many defects when both cutting edge and at the same time, can reduce the energy required at the cutting edge the pieces are related, chip formation, cutting machining cutter loading results relative position of workpiece and plays an important role in face milling, the chip thickness varies. A bit with a milling cutter which is about I was 30% larger than the cutting width and mill is located close to the center of workpiece in cutting chip is slightly thinner than the thickness in the central parts.
In order to ensure high enough average chip thickness / feeding teeth, a dental cutter suitable process must be designed correctly. By cutting the distance between the cutting edges effectively. Based on this value will be divided into 3 types: cutting grinding teeth grinding and milling cutter, cutter Thermae, cutter teeth.
Grinding and cutting thickness of face milling cutter head angle, central angle is the angle between the main blade and workpiece surface active, there are 45 degrees and 90 degrees angle a circular blade, cutting force in a direction of change will vary greatly with different principal 90 degree angle angle grinder, cutter, mainly produced radial impact force in the direction feed, which means that the surface composition will not bear a lot of pressure on the structure of a poorly reliable.
The main cutting angle of 45 degrees of axial and radial cutting force direction is equal, so the relatively balanced pressure, machine power requirements are relatively low, the production of short chip workpiece material particularly suitable for grinding chip is broken.
