### How to Calculate Punching Force (Formula & Tonnage

Perimeter = 20×4 = 80mm. Thickness = 3mm. Shear Strength = 0.3447kn/mm 2. Punch Force (KN) = 80 x 3 x 0.3447 = 82.728 KN Convert into tonnage:82.728 KN ÷ 9.81 = 8.43 Ton. For more details about the shearing strength including how to calculate it, you can refer to the answer from Wikipedia. Metal Hardness:The Definite Guide (with Hardness Chart A diamond cone with a cone apex angle of 120 ° or Ø1.588mm and Ø3.176mm hardened steel ball is used as the indenter and used in conjunction with the load. Under the initial load of 10kgf and the total load (that is, the initial load plus main load) of 60, 100 or 150kgf force, press the sample.

### Period 3 HW solutions - NCSU

adhesion, (3) diffusion, and (4) plastic deformation of the cutting edge. 17.7 Identify three desirable properties of a cutting-tool material. Answer. Three desirable properties are (1) toughness to resist fracture failure, (2) hot hardness to resist temperature failure, and (3) wear resistance to prolong the life of the tool during gradual wear.

Tap Recommendations for Specific Materials - Tapmatic Relief Angle In The Lead Of A Tap A small relief angle can be used in soft materials. Harder materials like stainless steel can be cut easier with a tap having a greater relief angle which reduces the friction. Tough materials like Inconnel and nickel can be cut more easily with an even greater angle.

### The Basics of Thread Rolling - PMPA

Different materials have different forming characteristics o In steel, sulfur creates flakes and slivers o In aluminum, Bismuth creates flakes and slivers o When cutting a thread, the major diameter = the blank diameter of the threads. 3. Mismatched Helix Angle 4. Different Rolling Conditions 5. Bend Force & Tonnage Calculators JMTUSADISCLAIMER:Actual bending force is affected by many factors such as friction between the material and the die, material thickness, material strength variations, rolling direction of the steel, work hardening and other parameters. This estimator calculates a force representative of the pressbrake requirement for air bending. Sizing of a machine or available die width should allow for up to 20%
