Week 8 - Challenge 1 - Base Bracket Design

Create the Base Bracket Plastic component through the given Class-A surface. To begin with, the tooling axis for the given Class-A Surface should be created meeting the requirements of the draft angle and at the end perform the Draft analysis on the model.

TOOLING AXIS

• The tooling axis is defined as the direction in which the mould opens or core and cavity open and closes.The selection of correct tooling axis is important to ensure the component is taken out perfectly and also the cost of the component should be less.I will start by inserting a geometrical set and naming it as a tooling axis.For creating the tooling axis I will analyze the model and first create the dummytooling axis.So on analyzing the model I found out that the z-axis will be perfect for creating the tooling axis.Because along the Z direction.

Draft Analysis of Class-A surface

• Draft analysis helps to detect if your drafted part is easily removable from the mold(in case of plastic component).All plastic components will have a minimum draft of 0.5 to 3 deg.If a mold wall is perpendicular to the part ejection ,there will be ample friction or interference between the mold and the part which will not allow one to release from the other.
