Video: 3+2 Mold Machining at Eifel
A maker of injection molds for high-appearance-quality parts describes the machine tool, software and strategy this shop uses to apply 3+2 machining.
Rick Hecker, Gary Schulz and Michael Nye of Eifel Mold & Engineering in Fraser, Michigan describe the shop's use of 3+2 machining to mill injection molds. The shop uses PowerMill software from Delcam to program a five-axis machining center from Hermle. One of the shop's specialties is mold tooling related to automotive steering wheels, an example of which is shown in the video.
Programming a robot with the same CAM software used for a multi-axis machine tool makes it unnecessary to “teach” the robot by jogging it manually from point to point and recording these point-to-point moves as the robot’s motion commands. Robotmaster is a software package that provides this CAD/CAM-based, off-line programming for robots. It runs fully integrated inside Mastercam CAM software for CNC machine tools.
The right way to program curves? A solution to yesterday's problems? The truth is probably somewhere in between.
The many rules of programming CNC cutter radius compensation can make machining problems difficult to diagnose and correct.
