![]() ![]() Single point cutters contain only one main cutting edge that can actively take part in shearing in a single pass during machining. Table: Differences between single point and multi point cutters Single Point Cutter Various differences between single point cutter and multi point cutter are given below in table format. A multi-point cutter can contain from two (drill or end-mill) to hundreds of cutting edges (abrasives of grinding wheel). operations are performed using single point cutter while, milling, drilling, knurling, reaming, etc. Turning, shaping, planning, boring, fly cutting, etc. Thus chip load per cutting edge reduces significantly. Contrary to this, a multi-point cutter consists of at least two cutting edges and all of them can equally participate in material removal action in a single pass. Thus one cutting edge removes entire volume of material in a single pass. Based on the number of cutting edge present, cutters can be classified as single point cutter and multi point cutter.Ī single point cutter contains only one main cutting edge that can actively participate in material removal action during machining. A cutting edge is basically one straight or curved edge produced by intersection of any two tool point surfaces (rake surface, principal flank surface and auxiliary flank surface). ![]() Whatever be the geometry of cutter, it must consists of a sharp cutting edge to swimmingly remove material requiring minimum effort. Therefore, cutter is a part and parcel of every conventional machining operation however, its shape and size may vary depending on the feature to be produced and operation employed. During machining, the machine tool actually holds the cutter and job, and at the same time it imparts desired relative motions (speed, feed, depth of cut). All these operations are carried out with the aid of a cutting tool that actually removes material from workpiece in the form of chips.Ĭutting tool, also called cutter, is a wedge shaped and sharp edged device that compresses a thin layer of workpiece material to shear it off the form of chips during machining. ![]() For example, turning, milling, threading, knurling, facing, drilling, boring, reaming, etc. Conventional machining processes are well established and it consists of a large number of operations for generating various features. Broadly these processes can be grouped as conventional machining (macro and micro), abrasive finishing and non-traditional machining (NTM). To cater the need of efficiently and economically machining a wide variety of materials in different ways, several relevant processes have emerged over the years. Machining or metal cutting is one secondary manufacturing process where excess material is gradually removed from the workpiece in order to impart desired finish, dimension and tolerance. ![]()
