Recently began looking into signs and other abstract pieces after having only done rectangular pieces for cabinets and furniture. Was also approached to produce internal elements of upholstered furniture (which require various curves).
Someone who wanted some signage produced supplied me with a DXF file that was created in Adobe Illustrator. Biesse Works did not like it.
After some tinkering and research, I discovered that bezier, spline and b spline curves are not readily machinable. Presumably this is because these types of curves are not mathematically defined (at least not usefully mathematically defined).
How then can one machine these irregular curve types? There must be a way. Do the curves that are readily machinable have a collective name or category that they belong to? Is there a way to convert bezier, spline curves, etc. into machinable curves? What have people been doing in order to create abstract shapes on a cnc router?
Thanks for your help.
