thread milling

Re: thread milling

Cheers Steve,

I've been wanting to do some thread milling for a while so I've got my chance. Will have a practice first ,does thread milling always start from the bottom of the hole ?

Re: thread milling

With Multi thread threadmills yes. Start from axis and exit from axis is your friend!! I would use it. Play with the parameters to see what they do.

Re: thread milling

Be aware that due to the lead in that the machine will go to a z depth slightly lower than the depth you specify as a blind depth. I bottomed out on a shank of a small threadmill early on in threadmilling by a thousandth or so.

Re: thread milling

Hello, Michael! I'm interested in Thread Milling tapered threads with an angle of 1.79 degrees per CREO3.

We get in the path of the 3 coordinates lines. Radius compensation is incorrect?

Привет, Майкл! меня интересует резьбофрезерование конических резьб с углом 1,79 градуса в CREO3.

Получаем траекторию перемещения в 3-х координатах линиями. Коррекция на радиус не отрабатывается?

Re: thread milling

Hello Olga,

can you explain further, what you mean with "get in the path of the 3 coordinates lines"?

Radius compensation is something you can define, but not really simulate in Creo, since the actual compensation value will be added on the machine.

Apart from this: It seems the original thread was rather generic on how to start with thread milling, while you seem to have a specific issue. Hence it may be better to open a new thread (this doesn't force users to go through a lot of non-related old posts to get to a new question).

But maybe you already did this? I saw you also opened this thread : threadmilling in creo 2.0

Or are these two different issue?

Re: thread milling

Hello, Gunter!

sorry my bad english!

can you explain further, what you mean with "get in the path of the 3 coordinates lines"? - we get Move around lines 3 coordinates:

X17.275 Y1.95 Z-2.428

X17.697 Y1.802 Z-2.44

X18.076 Y1.564 Z-2.452

Radius compensation will not work.

Re: thread milling

OK, what I see in the picture, is that there are two issues (maybe related with each other, maybe not):

  1. CUTCOM command is missing in the output
  2. There is a strange movement down from one thread to another

ad 1: Assuming the parameter CUTCOM ON is set, there normally needs to be lead in and lead out for appropriate CUTCOM commands output - I see in lead in, but not lead out.

ad 2: This is really strange! Are these two different thread definitions?

Maybe you need lead out and lead in between them to avoid the tool simply stepping down?

Re: thread milling

how to create program for variable pitch threading sequence, can it be created in turning itself or it requires mill-turn???????????
