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. 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:

open Explicit dynamics and rename as tension test

• Add steel 1006 material to the library

• import the geometry
• open model in mechanical apdl
• rename as cutting tool and work piece
• add steel1006 to the work piece and change stiffness behaviour of tool to be rigid

• generate mesh with using method tetra hedral For selecting geometry of tool

• insert sizing of mesh with edges selecting 4edges with number of divissions are 10

• select analysis settings change end time to be 7e+004

• select solution insert velocity of xcomponent 20000mm/s ycomponent=0 zcomponent+0

• insert fixed support for workpiece

• run the simulation
• same procedure have to be followed with changing velocity 15000m/s for case2

Results:

Case1:
