AIM ;

Create the screw boss and dog house for the centre console coin holder considering the design rules mentioned in the video.

General Rules for Screw bosses ;

• Draft of 0.5 degree on walls of boss
• Thickness is 40% of the nominal wall at the base.
• Height to diameter ration-3:1
• Fillet radius of max 0.25 mm.

C is where the doghouse contacts the back side of the surface

Doghouse wall thickness at the intersection of the part wall (C ) should be 40% or less than the main wall stock (T).

Height of (B) should be between 3-6 mm

Extract the base of Class A Surface and offset it with part thickness as 2.5 mm.

MARERIAL FOR DOG HOUSE;

POLYPROYLENE

WHICH TOUGHNESS

toughness

flexibility,

light weight and heat resistance are required.

TOOLING AXIS ;

The tool axis is a rotated an Angle 1 about the x-axis, then rotated an Angle 2 about the y-axis. The tool axis is a rotated an Angle 1 about the z-axis, then rotated an Angle 2 about the x-axis. The tool axis is a rotated an Angle 1 about the y-axis, then rotated an Angle 2 about the z-axis.

Draft Analysis ;
