Week 9 Machining with Planer Challenge
AIM:
To simulate the Machining with Planer .
OBJECTIVE:
To perform an explicit dynamics simulation to find out the Equivalent Stress, Total Deformation and insert a User defined result to calculate the temperature of the body. You need to perform this 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
.Select Explicit Dynamics, drag and drop into Project Schematic.
. Steel 1006 is chosen under Engineering Data.
. Under geometry tab, import the given geometry, double-click to open Space Claim to register the model and then update it.
. Body Interactions were set to frictionless.
. Set cutting tool as a rigid body.
. Mesh size was set to default.
. The mesh method was set to tetrahedrons for the cutting tool.
. An edge sizing of 10 number of divisions was given to the workpiece
. Under explicit dynamics tab, we set the analysis to 1 step with end time 7.5e-4s.
. Velocity of 20000mm/sec is given to the cutting tool in case 1 and in case 2 it is 15000mm/sec.
. The workpiece is fixed.
. Total deformation, temperature (user defined from Solutions worksheet) and Equivalent Stress plots are requested from the solver as outputs.
. Run the simulation by clicking on SOLVE.
These are the conditions of the simulation.

RESULTS
|
Case: Velocity |
Eq. Stress (MPa) |
Tot. Deformation (mm) |
Temperature (deg C) |
|
Case 1: 20,000mm/sec |
695.87 |
17.074 |
317.2 |
|
Case 2: 15,000mm/sec |
694.13 |
701.72 |
308.01 |
Here we can see from the results that the stress and temperature is more in case of case 1 but deformation is more in case of case2.
