Hi,
I've been trying cut a plaque that was created in Autocad. Most of the milling involves pocketing the letters and symbols. I've exported the file as an R12 dxf file. Once loaded into Lazycam, cleaned and optimized, some objects pocket ok, others do not. I went back and recreated the file with only a few objects that demonstrate my problems. I've attached both the original dxf and, in the next post, the Lcam results.
The file contains five objects that I want to pocket. From left to right, the first object consists of four straight lines and an arc, all connected. This will not pocket at all. The second object is a mirror image of the first. When I first tried to pocket it, it would not pocket like the first object. When I replaced the arc with a spline in Autocad, Lcam pocketed it OK. The third object is the form of the letter "S" that was created in Autocad from a series of lines, arcs, and splines. When I try to pocket it, I get an inside offset but no pocketing. The forth object (a "Z") is a mirror image of the previous "S", formed by using the Autocad "mirror" function. This one seems to pocket OK. The last object, the "S" was created by mirroring the "Z". I would expect it to have the same troubles as the first "S", but it pockets OK.
What am I doing wrong?
