roughing not working
roughing not working
I have a part that I am trying to generate a horizontal roughing path for. For some reason it is running the tool above the part and it never touches the stock. On the same part I can do a horizontal finishing and it works fine. Any clues where to look? I have been comparing the parameters of both operations and I can't seem to find what is different between the two.

Not sure that I understand.
How is the stock any different between the roughing and finishing? I made one piece of stock that is used for both.
I have attached the drawing.

Hi,
It is the stock value of 0.6 that is causing the problem. The stock amount is too large for the size of your part. This basically results in no areas to be machined. If you reduce the size of the stock to say 0.1 you will see that the cutter is able to get into the cavities to generate the cuts
The cuts about the top of the stock however are curious. I have sent this to development for them to take a look.

Ah ha. Now I see. This is the first time I have used roughing. So I take it that the stock value is the amount of stock that you want to leave on the part. Those weird cuts above the part disappear when I set the stock value correctly.
I take it that a value of .1 gives me .1" of material left even in the vertical axis? How would I set things if I wanted to leave .1 horizontally, but I wanted to leave only .020" vertical?
This forum is great. I wish the documentation and the help files were as good.

Yes the stock value is the amount of uniform stock you want to leave on the part. This is uniform in ALL directions. You cannot specify a stock value in the vertical direction and a separate stock value in the horizontal direction. Mathematically this is ambiguous since there is no definition on the stock in the non-vertical and the non-horizontal areas.
