Week 8 - Challenge 6 - Core & Cavity Design

TOOLING AXIS

• Check which plane is better for making tooling axis
• Extracted a surface from the body in that plane (x-z plane)
• Mark a point at the centre of the surface and makes a dummy tooling axis
• Make a y-z plane on the point and intersect it with the surface and forms two line for making a bisecting line through the point (line 1)
• Make a x-z plane on the point and intersect it with the surface and consider a line in the intersected line having a small inclination to the dummy tooling axis, then make a line through the point with an angle (4.5 degree) to the above considered line (line 2), the angle can be obtained by studying the surface using draft analysis
• Bisect line 1 and 2 through the point to obtain tooling axis

the angles between surface and tooling axis is shown below
