Week 9 Machining with Planer Challenge

Objective: To perform an explicit dynamics simulation to find out the Equivalent Stress, Total Deformation and also insert a User defined result to calculate the temperature of the body.

Required results for 2 cases: One will be with a cutting velocity of 20000mm/s and the other will be with a cutting velocity of 15000mm/s.

Procedure:

Step 1: Engineering Data

• Add Structural Steel 1006 from Explicit materials list in General Explicit material to the drop down list of materials.

Step 2: Geometry

• Right click on geometry and Import the Skill_Lync_Machining with Planer.x_t extension file
• Rename the Explcit Dynamics tab as Machining with Planer.
• Assign Structural steel 1006 to the workpiece and change Stiffness behaviour of cutting tool to rigid.
• Update the Model tab and open click Edit.

Step 3: Model and Meshing

• Open Model and under geometry assign names according to convenience for better understanding.
• Rename geometries as Workpiece and Cutting tool.
• Insert Patch Conforming Method-Tetrahedrons for the tool body.
• Insert Edge Sizing to the workpiece and enter 10 as number of Divisions.

Step 4: Connections

• Contacts:- Delete any contacts defined by ansys. Insert frictionless body interactions

Step 5: Setup

• In analysis settings we are going to simulate this case in 1 step but insert end time as 7.5e-4.
• Increase max energy error unitil solution converges in second case
• Insert a User Defined result with Function TEMPERATUREALL to view temperature distribution over geometries.

Results and Conclusion:

CASE #	Equivalent stress	User defined result to calculate the temperature of the body.(Maximum)	Total deformation
Units	MPa	Deg C	mm
Case 1-20000 mm/s Velocity	439.72	367.77	34.316
Case 2-15000 mm/s Velocity	634.15	364.75	23.612
