![]() When vendors or job shops open a file from a customer in their CAM program, the translation may not come through, introducing corruption in the model.ĬAD model showing corrupted faces that must be cleaned before a toolpath can be created. The problem is that CAD and CAM don’t always speak the same language. “As 5-axis machining has become more prevalent, the curvature of these surfaces can be very complex-hence the need for CAM software to develop toolpaths.” ![]() “Anytime someone has to machine a part, typically they’re starting with a 3D file,” said John Graham, senior product marketing manager at ANSYS, Canonsburg, Pa. Software solutions like SpaceClaim, developed by ANSYS Inc., can fix dirty models, with the end goal of creating “watertight” solids ready for machining. These files must be cleaned or repaired before toolpaths for machining the workpiece can be created. Job shops commonly receive corrupted or “dirty” CAD files from their customers.
