Tooling axis: Tooling axis is the direction at which core and cavity opens.

Procedure for creating tooling axis

First check the connectivity of the given Class A surface by using the Boundary or Join feature to visualized and repaired the open edges of the surface.
And then, analyse visually the best suitable plane or surface for tooling axis.
After that, extract a surface from CLASS-A Surface and then create a centre point on the surafce for the axis on the point.

then create a tooling axis from by using Normal surface line command on the extracted surface at the centre point.

Locators

Locators work as a 3 - 2 - 1 principle which is basically to fix a component to be machined or to be placed in an ideal position. There are a total of 12 degrees of freedom, 6 rotational and 6 translational.

Here locators are used to constraint the any 11 DOF. There are 4-way and 2-way locators

Heat staking

This is a fixing method of a plastic component to another dissimilar or similar surface or metal part. In this process, both of them are joined together by thermal welding. A Boss or a stud is made on the plastic part, which is then protruded onto the opposite part and reformed after the locators fix the part temporarily and then thermal welded on the boss.
