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

Anonymous — Thu, 27 Sep 2018 20:54:58 GMT

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.

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?

Very good video.

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

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.

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 ?!
