Haas - Programming a Manual Tool Change

[Lucky]

I need to run a program on our VF3 that uses more tools than the machine can hold. The behavior I'd like to get is:

 

The machine runs and changes tools automatically until near the end then begins stopping and allowing the operator to manually change tools for the last couple of operations.

 

We do this from time to time on our Mikrons w/ Heidenhain controls and it is simple but I've never attempted it on the Haas and I'm not sure it is possible. In the Haas control, the number of Tool Offsets available on screen exceeds the number of physical positions in the carousel, but if I try to call a tool number greater than 20 I get an alarm.

Could you G10 the Tool offset for each tool and have it update as you manually change the tools? So if you are using tool 20 for this have it update the length offset every time before the G43 is applied then you can do a length check to a 1-2-3 block to make sure they are using the right tool for each offset to avoid scrapping the part.

Can you just call all manual tools T20, and use a different D and H offset number for the extra tools? With operation comments and the correctly indexed offset numbers (T20 and D23,H23 for "T23").

 

I know its a pain, but it might work for you if you only have a few more tools than 20. Otherwise I would call Haas directly and ask to speak to an applications engineer about the Haas control. They would be able to tell you how to correctly use more than 20 tools in the control.

Good idea! So my last few operations would all be programmed as tool 20 with different length offsets loaded via G10. I need to check if it is possible to release and load tools in the spindle while M00 is in effect......

You can turn off H and T agreement on the control and the alarm shouldn't come up when using tool numbers greater than tool changer capacity(setting 15)
