232 revolution per minutes

hi hood,
Generation of Index Pulse in our board,
We are using the proximity switch which is fixed near the spindle and on spindle one steel material is fixed in such way that it comes near the proximity switch once in one rotation and proximity switch generates one pulse for one rotation. On time of pulse is 10% as compare of  OFF time of pulse. further these pulses are optically isolated and feed to MACH3 to measure the Speed of spindle rotations.

Please answer the question I asked earlier, what RPM are you threading at?
Hood

hi
i m threading at 229 RPM.

Ok, is your motor powerful enough? 6mm pitch will take a lot of Kw.
Does it cut OK if you just cut air rather than having the part in the chuck?
Open the SS Diags when you run the thread and see if there are any clues in there.
The SS is perfectly capable of doing that length of thread, I have done 800mm long threads for my pipe bending machine and they were perfect.

First time i checked with part in chuck.

after that i checked in air.

ok now i will thread in air.

but where in ss diags i will have to search clues?

can you any example?

The SS Diagnostice is from the Plugin Control menu.
I see you are only using a 250Hz controller frequency for the SS, have you tried faster, maybe 2KHz? Also I would recommend that you set the Y, A, B, C and Spindle to 32KHz in the SS Setup.

One other thing I am not quite clear about. Does this happen exactly the same with the PP?
Hood

not yet i tried 1khz and for y ,a,b,c,x and spindle 256khz.

i have done that changes what you said but problem is still happening.

and i dint understand about pp?

please tell me long form of pp.
