BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a parameter setting method for a machining milling cutter, and more particularly to a parameter setting method for a machining milling cutter set by an electric service. [Prior Art] The early traditional manufacturing industry used man-made heavy-duty simple tools to manufacture and produce. The process is not only time-consuming, but also of low quality. As the machining level is increasing, the processing products are increasingly complex, and the product precision is becoming more and more rigorous. The quality of the machining tool must be followed by the simultaneous advancement, and the quality of the tool grinding directly affects the cutting edge wear and product quality. If the grinding angle of the tool is not correct, the grinding is repeated, and unnecessary work is wasted, which inevitably increases the cost of the grinding tool. Therefore, how to improve the tool grinding technology and level, get good precision, and extend the tool life, it is necessary to accurately control the size of the tool and establish a fast and accurate working procedure. The existing milling cutter is manufactured by manually controlling the amount of grinding of the grinding. Generally, a conventional grinding machine is used. The grinding machine is provided with a chuck and a grinding wheel, and the processed milling cutter is clamped on the chuck, and the processing is performed. The manual rotation of the hand wheel is used to control the position of the grinding wheel, and the sharpening of the tool is performed by the grinding wheel. However, the existing methods of manually controlling the parameters of various milling cutters are inaccurate and unstable. After the different milling cutters are machined and ground, the angle of the grinding of the cutting edges cannot be maintained frequently, resulting in the quality of the milling cutters. Unable to stabilize 'increased the manufacturing cost of many machining cutters. 1268830 [Invention content] In recent years, with the development of high-tech and automation and the rise of personal computers, the speed of personal computer computing has been able to meet industrial requirements, which has prompted PC-

The knowledge and technology required to grind the tool is designed as an auxiliary grinding software and controller system. The program can easily generate NC programs suitable for the tool 1268830, thus greatly reducing the time for calculating and writing programs, and reducing the human error caused by manual input. At the same time, the software interface program is designed by engineers with extensive experience in grinding end mills. The operator does not need to memorize the cumbersome G and μ commands. The program will prompt the operator to input the tool appearance, grinding wheel, machine parameters and other conditions. i illustrates the meaning of the action, even if there is no user: the user will not be overwhelmed, when the NC alarm occurs, the operator can immediately query the debug method on the controller 'do not have to read the operation manual separately. The program path can be simulated before machining, thus reducing the mechanical damage caused by human error. All in all, the input of the data and the teaching operation can easily generate the Nc program and provide the controller to read and process. This is very helpful for the timeliness of the processing. [Embodiment] The preferred embodiment of the present invention is described by the processing parameter setting method of the end mill. The end mill is suitable for various purposes, and the main processing parameters for the side milling are included in the side milling. There are: the number of the knife, the shape, the helix angle, etc., among which: the end milling cutter generally has 2 or 4 blades, and the number of cutting edges greatly affects the performance of the single milling cutter. The 2 blades are larger than the 4-blade cutting groove. & 2 blade has a good spoon chip (1, but due to the small cross-sectional area, the rigidity of the tool itself is reduced. 'Easy bending in heavy milling, resulting in poor milling surface, also has a bad effect on machining accuracy. 4-blade cutting Poor performance, due to the large cross-sectional area of the tool, it can provide better rigidity. Generally, it can obtain better surface roughness of the machine. Since the feed of the 4-blade end mill is 2 to 2 times, it is 5~2 times. Can be high! 26883〇j rate of force mouth jq. — j&n. aa ra, the principle is: finishing using a larger number of cutting edges, roughing selection of the number of cutting edge is less. The helix angle is to reduce the vibration during cutting and to improve the sharpness of cutting. The lack of the factor is generally used.

The left and right spirals are end mills with both 'quasi-spiral and strong spirals. They can be used in a wide range. High-strength spirals around 6°° are used to mill M HrC (Rockwell hardness) with a high hardness of 50. Steel. The shape of the end-type end sharp knife is divided into two types: center hole and center hole. The center hole can not be used for center cutting, but it is easy to use blunt grinding. Without center hole, It can do center cutting, and the end knife must have a long and short knife and the long edge should be more than the center 〇. 5 is appropriate. The shape of the tool shape grinding can be divided into (radial) clearance angle and ( Radial) The cutting angle is two turns, and the relief angle can be subdivided into concave shape, flat relief, offset ~ crease, etc., the above (radial) relief angle and (radial) cutting angle The basic definitions and effects are understood by those who are familiar with the art' so they will not be repeated.
