.Describe the impact action of a Multi pair punch terminating tool?

A long workpiece, with the length-to-dimeter ratio that exceeds factor 10, is to be machined. Which workholding should provide the lowest deflection? Collet in the spindle and a live center in the tailstock Chuck on the spindle, a live center in the tailstock, and a follower rest Mandrel Solid center with a dog and a dog plate on the spindle, a live center in the tailstock Faceplate

Calculate the feed rate for a two-flute 1/ 4@in.-diameter carbide end mill to machine low-carbon steel.

Problem 2. (Determining Cutting Speeds in Machining Economics) A turning operation is performed with HSS tooling on mild steel, with Taylor tool life parameters n = 0.12, C = 60 m/min. Work part length = 450 mm and diameter = 80 mm. Feed = 0.20 mm/rev. Handling time per piece = 4.0 min, and tool change time = 1.5 min. Cost of machine and operator = $27/hr, and tooling cost = $2 per cutting edge. Find the a. cutting speed for maximum production rate and b. cutting speed for minimum cost Problem 3. (Production Rate and Cost in Machining Economics) For the two cutting speeds computed in problem 2, determine: the hourly production rate and a. b. the cost per piece.
