V. Description of the invention (1) [Technical field to which the invention belongs] The present invention relates to a special milling cutter, y it knife: ί first knife γ 糸 Πgan with a contour of a pre-formed template to guide the baht, /, Face 7 丨 The position of the uniform knife. The end face of the knife is machined according to the contour of the pre-formed template.—1. Asia uses milled and contoured holes with similar profiles. Non-circular and section-like holes are made; but the way of making quadrilaterals and making special features is long and the processing is correct; but the force is more shaped, because the material of the group will affect other parts of the sound. Know side. Most of the holes on the circular gauge need hexagonal shaped holes. The longer the discharge crop is the conductor, the pressed materials are often limited due to the need to produce very large holes. Therefore, the punching accuracy requires a shaped cross-section hole. [Previously it was easy to design and shape. For the purpose of stamping, the discharge rate is high for discharge. Easy stamping will change and affect the workpiece. Its cross-section is made with a pentagonal special cross-section. When the workman must use a slightly higher non-circular size of the ruler of this material to weave the structure, because of the presence of 'plum blossoms', usually Fangri Temple workpieces are made of non-forced materials. The high-pressure forming machine is made with a circular cross-section and some cross-sectional shapes. It is difficult to place when using the discharge method. The metal material is the type. Although the tensile strength is high, the residual stress is high. Processing methods Mechanical components are not the way, and the holes that are still needed need to be processed or discharged in a special shape. In addition, the effect of the work cannot be stamped, and it is suitable. To be changed again [Inventive content]

ju ^ ^ The purpose is to provide a new combination of non-circular cross-section holes. /, The tool 'makes it possible to process metal and non-metal holes at the same time, and has not been in Likou Gongde Λ' π ^, or around the hole Obviously, the main problem of tissue deformation and internal high residuals is that the axis rotates into a circular shape; however, due to the combined angle of the cross section and the sharp angle method, but visually, due to the guide of this tool? The I block and the master direction method are used to process non-tools. In the process of tool processing, a circular shape is produced by the current computer numerical control machine. The rotation of the tool makes the use of the cross section of the δ hole. The same radius of the cutter exists. Master tool processing is a process of former master tooling. Most of the tools are in the process of rapid rotation. The tool does not directly contact the template and guide the tool to guide the tool. It cannot make 360-degree rotation of circular cross-section holes. Originally, a hole was originally a spiral corridor that is often thought of. Although this device can be machined, all the contours can be machined. The whole plus one may be used. It will be touched, but moved; but turned and caused L The control knife results are still rounded. The template grinding of the manufactured spoon is also used because the cutting part of the processing side is round, and the imitation of the contour angle is damaged.

In order to make sharp corners of the guillotine forming milling cutter of the present invention, the present invention, the blade of the guillotine forming milling cutter does not design a spiral angle, that is, the spiral angle of the chip escape groove designed by the forming milling cutter of the present invention. It is zero degrees, and the screw angle of the chip escape groove is zero degrees so that the cutting edge forms a sharp angle and can contact the tip of the mold angle. In addition, the outer peripheral surface of the mold forming milling cutter of the present invention is in contact with the mold plate. Does not cause the template to wear when the outer periphery of the mold forming cutter of the present invention
