Hello and good day
I have a problem with the internal processing on our Spinner turning machine. The internal turning lathe tool wants to take too much chip in one go.
The lathe tool is stored correctly measured in the tool memory as type 500 with a cut position 2, L1=-9.557 L2=125 633 and R=0.4. The internal contour is pre-drilled with 21mm and should get drilled straight with cycle 95 to 29mm only. I engaged it with X20 and then it runs to X28 but on the display it says X29; then it tries to run until Z-48mm in one go. I have experimented with the position of the main and the subprogram a little bit but without success. Maybe somebody could tell me what I am doing wrong because I don’t have a clue. It seems to me as if the controller thinks it’s an outer contour which would make sense with the cutting depths that was entered in the cycle-but I have entered it under VARI in the cycle def. (11) for complete machining internal.

Please have a look in the training documents from Spinner : there is an internal processing with Vari (9) but as far as I know it’s external complete- could that be the reason?
Many thanks in advance
