The main difference between the Single and Multi-Point Cutting tool is the Single Point cutting tool contains Only one main cutting edge and the Multi-Point Cutting tool contains more than one cutting edge. So here we studied 15 points on differences between single and multi-point cutting tools.

Design of Single Point Cutting Tool

Cutting Tool or Cutter is a wedge shaped device that compresses the workpiece material during machining to gradually remove excess material by shearing in order to obtain desired shape, size and accuracy. Geometry, orientation and material are three important factors that influence performance of a cutting tool in accomplishing material removal. Every conventional machining operation employs a physical cutting tool. Although basic shape and feature of such cutting tool vary greatly with the type of operation it is intended to perform, every cutting tool mandatorily possesses a wedge shaped portion with a sharp cutting edge, which can assist shearing and thus cut material smoothly and efficiently. A particular cutting tool may contain one or more main cutting edges, and accordingly, it can be classified into three categories—single point, double point and multi-point cutting tools. As the name suggests, a single point cutting tool contains only one main cutting edge, a double point cutting tool contains two cutting edges, while multi-point cutting tool contains more than two main cutting edges.

The cutting tool can be classified in different categories. Depending upon the number of cutting points on the tool, the tools are divided as: 1 single point cutting tool 2 Multi point cutting tool. The tool having only one cutting point or edge is called single point cutting tool such as tool used for turning, boring shaping or planning, while the tool having more than one cutting point or edge is called multi point cutting tool such as tool used for drilling, milling broaching. All the cutting tools are designed to meet the purpose of removing material from work piece. All the cutting tools contain: 1 Cutting element 2 Mounting element. The design of cutting tools means the determination of all the dimensions and the shapes of all the elements of a tool, either analytically or graphically. To design the cutting element of the tool, it is necessary to know the kinetics of cutting.

In this paper we have established a new three-dimensional standard to specify single point cutting tool geometry. The paper models a single point cutting tool in terms of biparametric surface patches. Six new angles, called grinding angles, are proposed to define the orientation of these surface patches. The benefits of the new paradigm include ease of finite element based engineering analysis, simulation, and programming of the CNC tool cutter and grinder for tool sharpening. The proposed methodology is illustrated with a few numerical examples. This is a preview of subscription content, access via your institution. Rent this article via DeepDyve.

Difference Between Single and Multi-point Cutting Tool [Notes & PDF]

A cutting tool is a wedge shape device that removes material from blanks to give it a size and shape. In the single point Cutting tool, there is only a single point of contact between the tool and the workpiece. While machining or cutting operation, the cutting tool compresses a thin layer of metal around it and eventually shear it off when the pressure becomes excessive. To cut metals, three relative motions are required. Those are feed, velocity, and depth of cut. Though the cutting tool does not provide all these motions, the cutting tool is designed in such a shape that the machine can provide all those motions.

Permissible Cutting Speed, Feed and Depth of Cut Depth of cut has the greatest influence upon the cutting force, followed by feed, with cutting speed having the least influence. Feed has the greatest effect on surface finish when it is set according to nose radius. The cutting speed has maximum influence on temperature generated at cutting zone during machining.

The point of the tool is bounded by the face along which the chips slides as they are cut by the tool , the side flank or major flank the end flank or minor flank and the base. It is the intersection of the flan and the base of the tool. It is a curved portion at the bottom of the tool. The nose radius will provide long life and also good surface finish with it a sharp point on the nose. The tool cutting edge consists of side cutting edge major cutting edge , end cutting edge minor cutting edge and the nose. This angle also is known as the lead angle.

Я видел это своими глазами. Его слова не сразу дошли до ее сознания. Стратмор убил Чатрукьяна. Хейл, видимо, не догадывается, что она видела его внизу. - Стратмор знает, что я это видел! - Хейл сплюнул.  - Он и меня убьет. Если бы Сьюзан не была парализована страхом, она бы расхохоталась ему в лицо.
