Week 9 - Challenge 1 - Base Bracket Design

Draft Analysis

• It is the Analysis in which we analyse the Class A Surface for the Manufacturability or Mouldability
• In this We check whwther the pat can be mulded or not.
• Basic principle here is, Every wall should be at an angle of 0.5° to 7° to the Tooling axis.
• 3° is the nominal value
• 7° is for textured surfaces.
• 0.5° is minimum value, but it needs more investment (Generally not Preferred).

Tooling Axis

• It is an Axis in which we use for Moulding.
• In Simple Words it the Direction of movement of the core.

• Creation-
• First we Create a dummy axis for any reference purpose.
• We create it by Analysing the walls of the part.
• Bisecting method is also used in this.
• Prior we select any of two walls which are opposite and made a line along the direction
• Then a Bisecting line is created using those two lines as input.
• That Bisecting Line is considered as the Tooling Axis
