Cutting Tool Material
EXPERIMENT NO. 2
(A) Types of cutting tools:
Single-point cutting tools can be classified by their motion as linear or rotator, depending on whether they rotate while cutting. Linear cutting tools include tool bits (single-point cutting tools and broaches. Rotary cutting tools include drill bits, countersink and counter bores, taps and dies milling cutters and reamers. Other cutting tools, such as band saw blades and fly cutters, combine aspect of linear and rotary motion.
Following are different types of cutting tools: 1. Single point cutting tools 2. Multi point cutting tools 3. Form tools 4. Press tools
Single point cutting tools: Nearly all turning processes use single point cutting tools, this is, and tools that cut with only a single edge in contest with the work. Most turning is done with coated index able carbide inserts, but the tool material may also be high-speed steel, brazed carbide, ceramic, cubic boron nitride, or polycrystalline diamond. 75 percent of turning operations use just a few basic tool geometries. When tool holder itself rather than the actual insert. However, let’s first focus on the inserts. The geometry of an insert includes: 1. The insert’s basic shape 2. It’s relief or clearance angle 3. The insert type 4. The insert’s circle or “IC” size 5. The inserts nose radius
Definition of single cutting tool element and angles 1. Face: It is defined as a surface of tool on which the chip impinges. 2. Flank: It is defined s a surface below and adjacent to the cutting edge of the tool 3. Cutting edge: It is defined as a portion of the face edges that separate the chip from the work piece. It consists of side cutting edge, end cutting edge and nose of the tool. 4. Tool size: the size of the tool is defined as an element of tool which can be determined by the width of the shank, the height of the shank and total overall length of the tool. 5. Shank: the main body of the tool is called shank. 6. Base:
