Description of the invention (1) Scope of the invention The present invention relates to a tangent (same blade) cutting insert for mounting on a cutting tool for different cutting operations. BACKGROUND OF THE INVENTION Tangent cutting inserts are commonly used for rotary milling, such as slot cutters or extended slot cutters, turning tools or the like. Examples of the aforementioned usages can be found in U.S. Patent Nos. 3,4 1 6,2 0 9,3,4 9 0,1 1 7,3,7 0 1, U 7 and 4,790,693. One of the traditional tangent cutting inserts used in the present invention has a prismatic body. The body has a fixing screw hole and an operation front surface. The surface is usually parallel to the axis of the fixing screw hole and has an upper cutting knife. The lower cutting edge and the side edge extend between the two and meet each other via the blade angle. In general, because the upper and lower cutting edges have appropriate positive chip bevels, the front surface of the cutting insert is rubbed by adjacent cutting edges, so that it will extend from there to the inside of the cutting insert. The friction of the adjacent surface of the cutter before the operation of the blade causes the side edges and adjacent edges to be ineffective during the cutting operation because these side edges and edges cannot provide proper cutting geometries. Moreover, the blade corners are quite fragile and easy to break. The Central Bureau of Standards, Ministry of Economic Affairs, Shellfish Consumer Cooperative Du Printing (please read the notes on the back before filling out this page) The subject of the present invention is to provide a new type of cutting insert, which is particularly helpful to the aforementioned point of view. Summary of the invention All wire cutting inserts are provided. The insert has a body. The body has an operating front surface and at least three sides. The surface intersects the front surface at the cutting edge. The cutting edges meet each other via the edge. At least the blade -4. -As * used in this paper ΛΑϋ: Standard (CNS) Nag (plus x29VA, t) 4 3 6347 Printed by Real Consumer Cooperative of Central Procurement Bureau of Ministry of Economic Affairs 11 A7 B7 V. Description of invention (2) One of the knives The main cutting edge; the front surface of the operation includes a peripheral surface which extends from the blade and the edge along the entire length to the inside of the cutting insert. The cutting insert preferably has a fixing screw hole, the hole has a substantially parallel The front surface of the operation and the longitudinal axis substantially perpendicular to the main cutting edge. The cutting insert preferably has a scale and a prismatic body. The body should have an identical front surface and a rear surface extending between the front operation surface and the rear operation surface at both ends and two opposite side surfaces, and each other. Intersect at a pair of identical upper main cutting edges and lower main cutting edges, and a pair of identical auxiliary cutting edges extend between the main cutting edge and the four cutting edges. The auxiliary cutting edge is preferably adjacent to each edge, and part of it has the function of wiping. The other method is that a wiper part can be composed of the main cutting blades adjacent to the side blade. The side blades are preferably round and continuously meet the adjacent main cutting edge and auxiliary cutting edge. The cutting insert preferably has an imaginary reference plane passing through the end of the edge and the peripheral surfaces of each of the front and rear surfaces are oriented. In this way, an acute angle formed with the normal of the imaginary reference plane has along the main cutting blades, Predetermined values of auxiliary cutting edges and edge cutting blades> The main cutting edge of the cutting insert preferably has two lateral cutting edges extending outward from the Zheng near edge cutting blade, that is, extending from the imaginary reference plane toward the inside of the cutting insert, and A central cutting edge meets * According to the design of the present invention, the cutting insert has a cutting angle of eight scales, each with a main cutting edge and an auxiliary cutting edge. All cutting angles have a proper shape and cutting geometry.
