Affecting factor of tool life in machinability?
The life of tool is affected by many factors such as: cutting speed, depth of cut, chip thickness, tool geometry, material or the cutting fluid and rigidity of machine. Physical and chemical properties of work material influence tool life by affecting form stability and rate of wear of tools. The nose radius tends to affect tool life.1. Cutting speed: Cutting speed has the greatest influence on tool life. As the cutting speed increases the temperature also rises. The heat is more concentrated on the tool than on the work and the hardness of the tool metrix changes so the relative increase in the hardness of the work accelerates the abrasive action. The criterion of the wear is dependent on the cutting speed because the predominant wear may be wear for flank or crater if cutting speed is increased.2. Feed and depth of cut: The tool life is influenced by the feed rate also. With a fine feed the area of chip passing over the tool face is greater than that of coarse feed for a given volume of swarf removal, but to offset this chip will be greater hence the resultant pressure will nullify the advantage.3. Tool Geometry: The tool life is also affected by tool geometry. A tool with large rake angle becomes weak as a large rake reduces the tool cross-section and the amount of metal to absorb the heat.4. Tool material: Physical and chemical properties of work material influence tool life by affecting form stability and rate of wear of tool.5. Cutting fluid: It reduces the coefficient of friction at the chip tool interface and increases tool life.
What are the basic concepts of material removal using machines.?
Material removal using machines involves several fundamental concepts, including cutting, grinding, and shaping materials to achieve desired dimensions and surface finishes. The process typically utilizes cutting tools that remove material through mechanical action, such as shearing or abrasion. Key factors influencing material removal include tool geometry, cutting speed, feed rate, and the properties of the material being processed. Effective cooling and lubrication are also crucial to enhance tool life and improve surface quality.
What are the desirable properties of a cutting tools?
1. cutting tool should be more harder than the material to be cut otherwise it can break during the process. 2.cutting tool should be tough.well,there is much difference between the word hard and tough. hardness implies resistance to scratch whereas toughness measure ability to withstand shock. 3.The tool should be able to withstand the heat generated in the metal cutting process. Also, the tool must have a specific geometry, designed so that the cutting edge can contact the workpiece without the rest of the tool dragging on the surface of the piece part surface. The angle of the cutting face is also importantol must be able to withstand the heat generated in the metal cutting process. The angle of the cutting face is also important as is the flute width, tool margin and tool material. SUGGESTIONS ARE WELCOME
How do you increase cutting tool life?
1) use it on the material it was designed for - Check for hidden nails 2) use them for the task they were designed for - Don't use a chisel to pull staples or to pry with. 3) Don't let cutting edge make contact with other tools - The bottom of the tool box is not the place for a edged tools and drill bits For lathe and milling machine cutting tools: * use at the correct speed for the tool and material * use coolant/lubricant to minimise heat where appropriate for the material
What are two major factors affecting cutting speed selection?
Two major factors affecting cutting speed selection are the material properties of the workpiece and the type of cutting tool being used. The hardness, toughness, and thermal properties of the material influence how quickly it can be machined without causing tool wear or damage. Additionally, the tool's material, geometry, and coating can determine its ability to withstand heat and wear, thus impacting the optimal cutting speed for effective machining.

Why does machining chip become thicker after cut?
Machining chips become thicker after a cut due to several factors, including the increased material deformation and the heat generated during the cutting process. As the cutting tool engages the material, the workpiece experiences plastic deformation, which can lead to larger chip formations. Additionally, higher cutting speeds and feed rates can cause more material to be displaced, resulting in thicker chips. The tool's geometry and the properties of the material being machined also influence chip thickness.

What is peripheral cutting?
Peripheral cutting refers to a machining process where the cutting tool engages the workpiece along its outer edge or periphery. This technique is commonly used in operations like milling and turning, where the tool removes material from the surface to shape or finish the part. The process allows for efficient material removal and can produce precise dimensions and surface finishes. It contrasts with other cutting methods, such as face cutting, where the tool engages the material from a flat surface.
What is a guillotine tool?
Boringly, a device for cutting paper or other sheet material.
What is the best tool to use for cutting styrofoam?
A hot wire cutter is the best tool to use for cutting styrofoam because it melts through the material smoothly and creates clean edges.

What does die cutting do?
Cut out pieces of a material from a sheet of that material. The pieces can be any shape because the die doing the cutting was custom machined to the required shape by a Tool and Die Maker.
