Gentlemen, I see a problem with using "gcode generating" software languages to machine complex geometries. In my world all "gcode generating" software languages will undercut or gouge the material deemed to be the desired material to include in the desired part. This happens at random times. Usually only when a complex geometry is modified. Sometimes the modification is so minor it is insignificant or so you would think. Simple shapes are hardly ever a problem. Complex shapes may need to have the cutting strategy altered to allow generation of clean g code. Seeing the undercut on the screen or in some verification software is not generally a problem. Discovering the undercut in the machined part can be frustrating. I remember running a Mazak mill with the M2 control. The control had 3D surface cutting capability. You needed to watch the cut on the screen prior to turning the mill loose on the material. I see value in using a language to cut simple parts but complex 3D surfaces could yield some unwanted results. thanks Stuart
