And that is to be expected isn't it?
G-code is new to me too, and tool comp is one of the more difficult things.
But you have to start the tool comp on a lead in move, that will follow a different path for differing tool sizes, so it should be done through material that does not belong to your part. It might be explained as a move starting with the center of the tool at the programmed line, and ending up with the cutter to the right (G42) of the end of your line by half a cutter diameter. And the cutter edge will have passed the tangent to the endpoint of the line by half a cutter diameter. The path should continue straight ahead or to the left, or your program will *****. This is because you told it to gauge into your part. So much I believe I got right. but the not so easy part is how to do this. Especially approaching the inside of a circular pocket.
Anyone care to explain this in an easily understood way?
Or to correct me if I'm wrong in what I wrote? |
