Week 9 Machining with Planer Challenge

Aim: Aim of the task is to perform a explicit dynamic analysis for a planer machining operation in two cases. In first case the the velocity of the tool is 20000mm/s and in second case the velocity of the tool is 15000mm/s.

Details of simulation:

• For the simulation an explicit material steel 1006 is selected. The selected material is used for the work piece and structural steel is used for the tool.
• For the tool tetrahedrous mesh method is used.
• For the workpeice a default mesh is used.
• The tool has assigned a velocity to move with.
• The workpeice has assigned a fixed support.

Results:

Case 1: 20000 mm/s

Total deformation:

Equivalent stress:

Case 2: 15000mm/s

Total deformation:

Equivalent stress:

Conclusions:

We can observe that the simulation with less velocity (23.635mm) has a leser deformation compared the simulation with higher velocity (43.65mm).

Also the maximum stress developed is lesser in the simulation with lesser velocity(676.44MPa). The stress in simulation with higher velocity: 684.64MPa.
