What is normal stress and shear stress?

There are two types of stress that a structure can experience: 1. Normal Stress and 2. Shear Stress. When a force acts perpendicular (or "normal") to the surface of an object, it exerts a normal stress. When a force acts parallel to the surface of an object, it exerts a shear stress.

How to Calculate Normal stress due to tool?

Normal stress due to tool calculator uses Normal Stress = sin(Shear Angle)*Resultant Cutting Force*sin((Shear Angle+Mean Friction Angle on Tool Face-Working Normal Rake))/Cross Sectional Area of Uncut Chip to calculate the Normal Stress, Normal stress due to tool is when a force acts perpendicular (or "normal") to the surface of a workpiece, it exerts normal stress. Normal Stress is denoted by σ_n symbol.

How to calculate Normal stress due to tool using this online calculator? To use this online calculator for Normal stress due to tool, enter Shear Angle (ϕ), Resultant Cutting Force (F_r), Mean Friction Angle on Tool Face (β), Working Normal Rake (γ_ne) & Cross Sectional Area of Uncut Chip (A_c) and hit the calculate button.
