For the horizontal milling machine machining plane, cut teeth in the boundary of the processing cutter on the tooth is separated into two sorts of straight teeth and helical teeth; if the quantity of teeth can be partitioned into coarse and fine teeth two sorts of winding teeth coarse processing cutter The quantity of teeth is little, the high quality of the tooth, the chip space is vast ...
(i) introduction to the processes, (ii) the orthogonal cutting model and tool life optimization and (iii) process planning and machining planning for milling. 8.1. Introduction to the processes 8.1.1. Sawing Sawing is used to cut the correct sized workpiece from a large raw material stock. There are several types of saws (Figure 1):
The first method, conventional milling, is more common with manual milling machines and cuts with a spindle rotation vector that's the opposite of the cut direction. The tool rotates in a way that cuts the workpiece from smaller thickness to larger thickness (see Figure 2).
Introduction to CNC Cutting Tools. In the modern manufacturing world, Computer Numeric Control (CNC) machines are widely used. CNC machines are computer-controlled, high-precision tools designed to make accurate movements in a repeated pattern.During the 1940s and 50s, CNC cutting tools were introduced in the industrial world.

•The cutting speed is mostly determined by the material to be cut and the material of the tool. To find the right speed for any task, refer to the Machinery's Handbook or tool manufacturer reference. •To calculate the proper spindle speed, divide the desired cutting speed by the circumference of the tool expressed in feet.
Introduction Milling produces 3-dimensional shapes with a rotating multi-edge cutting tool. The cutting tool can be programmed to move against a fixed workpiece in almost any direction. Milling tools remove material by their movement in the machine and from their shape. Audience
