Week 10 - Challenge 2- Attachment Feature Creation (Dog House)

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.

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

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.

THE NATURE OF THIS CLASS A SURFACE RENDERS SOME SURFACES NOT BEING CLEARED WHICH IN AN OEM CAN BE CHANGED BY THE CLASS A DEVELOPMENT TEAM.

IN ESSENCE, WE CAN PROCEED WITH THE SELECTED MAIN TOOLING AXIS.

DOGHOUSE:

THE CREATION OF THE DOGHOUSE IS DONE IN THE DRAFT DIRECTION (SWEEP IN THIS CASE OF THE UNDERLYING SKETCH) OR PAD (IN THE PLANE PERPENDICULAR TO THE MAIN TOOLING AXIS).

THE NATURE OF THE SURFACES WHERE THE DOGHOUSE IS PLACED IS NOT PLANAR BUT CURVILINEAR

THE WALL THICKNESS AT C WILL BE 0.4 X 2.5 MM = 1MM WITH THE ADDITION OF THE 30 PERCENT DEVIATION.

THE MAIN TOOLING DRAFT OF THE DOGHOUSE IS 1.5 DEGREES WHILE THE SIDE CORE DRAFT IS TAKEN AS 0.5 DEGREES.

A SIDE CORE AXIS IS CREATED TO ALLOW FOR THE SIDE CORE DRAFTING
