Turning Operation Forces Numerical Example Question Solved Practice | Unorthogonal4|PT|BITS Goa Mech

The video is a part of topic non orthogonal machining which is an extension of orthogonal machining. This topic comes under the course of production technique, manufacturing processes and industrial engineering in Mechanical Engineering. The video is about turning operation under the topic of non orthogonal machining operation. It solves a numerical example question for practice. It explains about the modification of modelling of turning operations which includes modifications of modelling equations, force triangles, trigonometric relations and formula for cutting forces and power required for machining. It explains about the machining parameters such as uncut chip thickness, width of cut, depth of cut, cut chip thickness, feed rate, rotation speed of spindle and many other. It explains about the force triangle which includes the forces such as cutting force, normal force, radial force, feed force, thrust force, total force and Merchant's solution or Merchant's triangle. It also explains about workpiece material property such as shear strength of workpiece and friction coefficient between chip and rake surface of tool. It also explains about various angles involved in velocity trinagle which are shear plane angle, friction angle, rake angle, back rake angle, side rake angle and equivalent rake angle.
