Week 9 Machining with Planer Challenge

Objective: To perform an explicit analysis of a planer machining a flat workpiece using the explicit dynamics analysis system of ANSYS Workbench.

Procedure:

1. Contacts: Not Defined.
2. Body Interaction:
   1. Formulation: Penalty.
   2. Type: Frictionless.
3. Meshing:
4. Boundary Conditions:

Analysis:

1. Case 1:
   1. Total Deformation:
   2. Equivalent Stress:
   3. Temperature:
2. Case 2:
   1. Total Deformation:
   2. Equivalent Stress:
   3. Temperature:

Result:

Cases	Planer Velocity (mm/s)	Total Deformation (mm)		Equivalent Stress (MPa)		Temperature (°C)
		Maximum	Minimum	Maximum	Minimum	Maximum	Minimum
Case 1	20000	46.696	0	659.78	5.0006	396.59	19.85
Case 2	15000	32.79	0	666.45	3.2806	345.29	19.85

Conclusion: The maximum total deformation and the maximum temperature attained is greater in case 1 than in case 2. The maximum equivalent stress is however greater in case 2 than in case 1. The total duration of the machining is 0.00075 s with maximum energy error of 0.1 in both cases.
