________ occurs due to material built-up at the cutting edge.

________ occurs due to material built-up at the cutting edge. Correct Answer Crumbling

During the cutting of soft and tough materials, the formation of built-up edge takes place, part or entire of which breaks away periodically and some portion of the cutting edge may also be taken away along with the built-up edge, this leads to deterioration of cutting edge by crumbling.

Consider the following statements: 1. HSS tools wear very rapidly, whereas in cemented carbide tools, even though hardness is retained, crater wear can occur due to solid-state diffusion. 2. Cutting tools made of Super-HSS, also known as cobalt-based HSS, are made by adding 2% to 15% of cobalt which increases the cutting efficiency at heavier cuts by increasing the hot hardness and wear resistance. 3. Tools failure due to excessive stress can be minimized by providing small or negative rake angles on brittle tool materials, protecting tool tip by providing large side-cutting edge angles, and honing a narrow chamfer along the cutting edge. Which of the above statements are correct?
Flank wear occurs mainly on the 1. Nose part of the cutting tool 2. Front relief face and side relief face of the cutting tool 3. Face of the cutting tool at the shortest distance from the cutting edge Which of the above is/are correct?
