Week 9 Machining with Planer Challenge
MACHINING WITH PLANAR SURFACE
AIM:
TO ANALYSE AND SIMULATE FOR THE GIVEN CASE USING THE MACHINING WITH PLANAR SURFACE MODEL.
MODEL:
THE MODEL HAS BEEN PROVIDED WITH WORKPIECE AND THE TOOL.
MATERIAL:
THE MODEL HAS BEEN IMPLEMENTED WITH EXPLICIT MATERIAL STEEL 1006 FOR BOTH THE WORKPIECE AND THE TOOL.
CONTACTS:
A DEFAULT CONNECTIONS HAS BEEN DETECTED WITH THE MODEL, WE ARE REMOVING THE DEFAULT CONNECTIONS, AND WE ARE ALLOTING THE BODY INTERACTIONS AS IT IS WITH THE FRICTIONLESS TYPE.
BODY INTERACTIONS:
THE DEFAULT BODY INTERACTIONS HAS BEEN KEPT TO FRICTIONLESS
MESH:
WE ARE PROVIDING THE WORKPIECE TO BE FLEXIBLE AND THE TOOL AS RIGID BODY, WE ARE HIGHLY CONCENTRATING ON THE WORKPIECE THAN THE TOOL, SINCE THE TOOL IS MADE OF COMPLEX GEOMETRY, WE ARE PROVIDING TETREHEDRAL ELEMENTS, WHERE AS FOR THE WORKPIECE WE HAVE CREATED A 10 DIVISIONED HEXAHEDRAL ELEMENTS.
ANALYSIS SETTINGS:
THE END TIME HAS BEEN SET TO 0.00075 SEC AND FOR THE SECOND CASE THE ENERGY ERROR HAS BEEN SET UP TO 0.5. WE HAVE SET THE INITIAL CONDITIONS AS IT IS AS DEFAULT.
FIXED SUPPORT:
THE BOTTOM END OF THE WORKPIECE HAS BEEN KEPT FIXED FOR THE SIMULATION TO PROCEED.
VELOCITY:
- CASE 1: 20,000 mm/s:
THE TOOL HAS BEEN IMPARTED WITH THE VELOCITY OF 20,000 mm/s IN THE DIRECTION OF X.
- CASE 2: 15,000 mm/s:
THE TOOL HAS BEEN IMPARTED WITH THE VELOCITY OF 15,000 mm/s IN THE DIRECTION OF X.
TOTAL DEFORMATION:
CASE 1 :
CASE 2 :
EQUIVALENT STRESS(VON-MISES):
CASE 1 :
CASE 2 :
EQUIVALENT PLASTIC STRAIN:
CASE 1 :
CASE 2 :
EQUIVALENT STRAIN:
CASE 1:
CASE 2:
RESULT:
FROM THE ABOVE SIMULATION WE CAN COMPARE THE RESULTS AND CONCLUDE THAT WHEN INCREASING THE VELOCITY, THE WORKPIECE EXPERIENCING THE MINIMUM STRESS , IN THE ABOVE SIMULATION WE CAN SEE THAT FOR 20,000 mm/s THE STRESS GENERATED IS 673.36MPa, WHERE AS FOR THE 15,000mm/s THE STRESS GENERATED IS 674.47MPa.
