Week 9 Machining with Planer Challenge

OBJECTIVE:

To perform a explicit dynamics simulation for a planar machining and obtain the equivalent stress and total deformation.

METHODOLOGY:

• First add the required explicit material to the engineering data
• assign the explicit material to the workpiece.
• 
• apply the mesh and perform the edge sizing to the workpiece.
• 
• give the step end time in the analysis settings and fix the bottom surface of the workpiece.
• 
• give the velocity to the cutting tool and obtain the results by changing the velocity.

CASE 1: velocity=20000mm/s

CASE 2:velocity=15000mm/s

CONCLUSION:

From the above figures we can say that stress developed in the workpiece is increased as the cutting speed decreased and due to low cutting speed less deformation of workpiece is occured.
