Week 10 - Challenge 3 - Door Trim Lower with Engineering Features

DRAFT ANALYSIS:

THIS AIDS IN UNDERSTANDING WHETHER OR NOT THE PART TO BE MOULDED CAN EASILY BE REMOVED. THE FACES THAT ARE DRAFTED RENDER THE PART TO BE REMOVES EASILY DURING THE EJECTION PHASE OF INJECTION MOULDING PROCESS.

TOOLING DIRECTION:

THE TOOLING DIRECTION IS DETERMINED BASED ON THE DRAFT ANALYSIS CONDUCTED W.R.T THE TOOLING AXIS. IN ESSENCE, THE AXIS THAT ALLOWS ALL THE RELEVANT SURFACES TO HAVE THE DESIGN DRAFT IS CALLED TOOLING AXIS.

ONE OF THE APPROACHES TO BE NOTED IS THE REFERENCE OF THE GLOBAL COORDINATE SYSTEM IN THE MAKING OF THE TOOLING AXIS. THIS HELPS TO KEEP A STANDARD THROUGHOUT THE DEVELOPMENT OF THE VEHICLE FOR THE OEM. DEVIATIONS FROM THE GLOBAL CSYS CAN BE ALLOWED ALBEIT WITHIN CERTAIN LIMITS.

THE TOOLING AXIS CREATED CLEARS THE CLASS A SURFACE FOR 3 DEGREES OF DRAFT ANGLE AND HENCE CAN BE USED FOR FURTHER DEVELOPMENT

THE DRAFT ANALYSIS OF THE ENGINEERING FEATURE IS DONE FOR A DRAFT ANGLE OF 1.5 DEGREES (1.45 AS THE SOFTWARE USES AN INLCUSION OF THE 1.5 FOR THE RED DATA)

THE DRAFT ANALYSIS FOR THE PART SHOWS SOME ERROR SURFACES WHICH CAN ONLY BE ADDRESED EFFICIENTLY BY THE A SURFACE DEVELOPMENT TEAM IN AN OEM.

NOTE:

THE SOFTWARE COULD'NT IMPORT THE POINTS DUE TO SOME LOCAL PC ISSUE, SO NEW POINTS WERE GENERATED USING THE "ON SURFACE " UNDER THE POINT CREATION DIALOG BOX ONTO THE B SIDE SURFACE OF THE PART
