disable the "spindle off" check for turn tools on mill mach

Hello Everybody,

I have created a 5-axis milling machine on vericut in order to simulate a 6-axis turning process (turning tool is located in the spindle, which revolves around Z axis, therefore there is a third rotary axis defined: C which revolves around Z axis)

As it is a 6-axis process, spindle rotation is not switched on, it is used as the C axis.

During the simulation , I get an huge amount of the following error messages: "Collision between the cutting zone of the tool ### and the machined part with the spindle turned off at line ####... (translation from the french).
Those errors slow down incredibly the simulation.

Is it possible to disable this "spindle on" check with turning tools on milling machine ?

n.b.: I don't care about material removal (it is actually no more than 0.4mm). I just want to check whether the tool holder collides with the stock or not.

Thank you in advance for your help
Best Regards

The best way to configure this, would be to turn on the spindle with a C command, resulting on the same results on the part.
Configuration > Word/Address...
under Registers, select C *
Select the condition * *, with CAxisMotion
right-click, Add/Modify
Macro name = ActiveSpindleActiveTool
Add (leave the panel open to add more macros)
Macro name = ActiveSpindleOnOff
Override Value = 1
Add (leave the panel open to add one more macros)
Macro name = ActiveSpindleOnOff
Override Value = 0
check the box "Process After Motion"
Add
Close

This will turn on the spindle with a Caxis motion but will turn it off inmmediatly after the C axis command. This will avoid the error without affecting your simulation

Thank your for your help, SergeV, but it doesn't work very well.

You are right, I get no more error messages. Nevertheless, simulation is even slower than before. Because for every C move, vericut spins the active turning tool around Z axis, thus creating a revolved body. At the end of every C moves, turning tool returns to its normal shape. These constant transformations slow down simulation in a worse way than before.

Is it possible to disable this tool shape update ? That would solve my problem. I have searched for such a macro but haven't found it so far.

Re: disable the "spindle off" check for turn tools on mill mach

You could turn on the spindle with C axis but only turn it off with the next tool change. So, when this special turning tool is loaded, it will stay in a revolved state until the next tool is loaded.

Since you always have the spindle off during a tool change (I hope), you could add the spindle off macros to your tool change macros. If the Spindle is already off, it won't affect anything.

Just ideas...
