CNC PROGAMMING

		Cavity Insert Solid Model Contoured surfaces created with 3D solids cut with surfaces. The original part file was created in Pro-E, but due to the poor IGES translation of the multiple complex surfaces, I had to create my own core and cavity from the hard copy.
		3D Vertical Finishing Toolpath Toolpaths are generated from the solid model with NC Polaris working inside Mechanical Desktop. The toolpath shown is semi-finishing with constant stepover. The finishing toolpaths applied are constant scallop with minimal cusp height to minimize bench polishing.
		Completed Aluminum Cavity Insert Actual machined and polished cavity insert ready to set into the mold base.
		2-1/2 D Roughing and Finishing Toolpaths The pocketing, contouring and finishing toolpaths are applied directly to this solid model of a vacuum form tool. Toolpaths can be moved, copied, arrayed, sketched, etc with the basic AutoCAD commands.
		Fadal VMC 4020 I selected this CNC machine for the Toolroom. It is optimized for High Speed Machining with Fadal Surface Analyzer, feed rate optimization and DNC spoon feeding from an ordinary PC.
		Bridgeport DX-32 CNC At the Bridgeport control with a trainee. I trained a team of assistants to set up and operate the CNC machines in the Toolroom at POP Displays.
		Injection Mold Core Roughing a core on the Bridgeport. Look-ahead is nil as it can only process a couple of blocks of code at once. I prefer the Fadal for complex 3D finish cuts where I can apply HSM strategies.
