Week 9 - Project 1 - Door Trim Lower with Engineering Features

1) SELECTION OF TOOLING AXIS

TOOLING AXIS IS PREFFERED IN DIRECTION OF Y AXIS AS IT WILL BE EASIER FOR THE MOULDING PURPOSE ,AS MOST OF THE PART CAN BE PRESSED UNDER THIS DIRECTION.

DRAFT ANALYSIS

1) A CLASS SURFACE:-

FROM THE ABOVE PIC ITS CLEAR THAT ALL THE SURFACES ARE INCLINED MORE THAN 3 DEGREES AWAY FROM THE TOOLING AXIS ,AS ITS SHOWING THE GREEN COLOR.

2) DRAFT ANALYSIS OF PART :-

AS IT SHOWS RED AND GREEN COLOR ,IT MEANS THAT THE SURFACES ARE INCLINED MORE THAN 3 DEGREES IN POSITIVE AND NEGATIVE DIRECTIONS OG THE TOOLING AXIS .

THE LOCATORS ARE APPROX 20MM ABOVE THE SURFACE WHILE THE HEAT STAKES ARE APPROX 15MM ABOVE ,HENCE THERE IS 5MM DIFFRENCE ,THE LOCATORS AND HEAT STAKES ARE DRAFTED AT AN ANGLE OF 0.5 DEGREES.

THE PINK SURFACE IS THE BACK HOLDING SURFACE WHICH THE LOCATORS AND HEAT STAKES WILL PENETRATE ,AS WE CAN SEE THE THE DOOR TRIM CAN ONLY MOVE ALONG THE TOOLING AXIS DUE TO OTHER DEGREE OF FREEDOM BEING FULLY CONTRAINED BU THE LOCATORS .
