How to adjust post processor for getting G codes ijk (spiral) in constant Z

[Anonymous]

Greeting, 

Dear Madam/ Sir

Around more than 5 years, I am grappling with receiving ijk G codes associated with spiral in constant Z strategy.

For this purpose, I have done some researches as well as surfed the net to find how can I getting ijk G codes when I use the constant Z strategy in POWER MILL software.

So I was extremely wondering if you would mind guiding me if how can I receive G2 G3 codes when I use the constant Z in Spiral mode.

Best regards,

Mohammad Asalpisheh

I have been down this road in the past, it's my understanding that you cannot get arc output unless the movements are in a principal plane. In other words, no spiral movements or 5x moves.

what post are you using on what controller?

I have used FANUC post processor

Many thanks for your info,

I have done all details based on related info mentioned in post, but I could not receive all statement in ijk g codes,

So could you please give me further details?

[Anonymous]

yes! that is correct, would you please let me know if how can I solve my current problem?

Very good video.

Additionally, to reduce the number of toolpath segments, set up the point distribution:

Many thanks!

it was related to FANUC post processor

I also try this but this technique did not work with spiral in constant z ...

any one can help me ... ?

and also can any one tell me how to generate codes in the form of I J K with optimized constant z Finishing strategies ..

As M.Hennig noted earlier, you cannot get arc output unless the movements are in a principal plane.
Exception, if your CNC-controller support arbitary plane arcs (like Sinumeric 840D), this option is configured in PostProcessor.
So, the only way out is to configure the point distribution for smooth machine movements.

Thanks for your reply its very helpful but from where we can get this fanuc helical file.

waiting for your reply 

thanks

hi. this for you

[Anonymous]

I have same problem , in powermill 2020 i can get helical output arcs with constant z but when the tolerance is below .05mm or the step down value increases near  0.4  , the output is linearized.whats the problem ?!

Can you help me how can to output NC with i,j,k Value in spiral mode
