c axis rotation

[red sox fan]

In a five axis program when indexing from A 0. C0.  to lets say A-45. C45. then back to A0. C0. the C axis stays at C45. 

I want the C axis to go back to C0. is there a command in the post that can be added to force the C axis to zero anytime the

A axis is at  A0. ?

If your post is based on the generic 5 axis post, the C axis does not necessarily need to return to C0, the XY will be rotated around it.  You could force a reset of the C to 0, but I would worry about potential side effects of doing so, especially for 5 axis motion.

Why do you want this to happen? You start adding logic to a post to force something like this and I see a major crash happening. Most posts have logic to change the Axis direction using the misc and it up to each programmer to figure out how to best use them for their programming process. You start forcing a post int0 singularity and all bets are off as how Mastercam will handle the process.

I would like it for a number of reasons, other softwares do it so is it just a mastercam thing?

It helps to remove unnecessary movement.  If you must, you could throw in a force tool change in your operation or better yet put in a bogus point toolpath (say right at your retract point) to force C to rotate to 0  before your A0C0 move.  This might be a bit of a PITA, but it will maintain the integrity between Mastercam and your posted code.

No it is not a Mastercam thing. It is a process thing. You made a very broad statement and didn't give a specific example or file for someone to understand exactly why, when, where or how you need or want this. Since it was such a broad statement I made a broad answer back. Funny someone can say are you going to Europe? Yes I am going to Europe. Where are you going to in Europe? I am going to Italy. What city are you going to? I am going to Rome. Are you going to see any of the attractions? Yes I am going to see the Statue. Which one? and etc....

 

Yet people come in all the time and ask a general questions and then expect exact answer as to what Statue in what country they wanted to see and understand everything about it.

 

You tell any CAM System without some sort of Logic to always do this:

 

 

is there a command in the post that can be added to force the C axis to zero anytime the

A axis is at  A0. ?

 

You are asking for a possible crash. Is the operation is meant to go to A0 while in the middle of a 5 Axis operation and the C should be at anything other that C0, but you wrote logic in the post to force C0 anytime it sees A0 then you are possibly going get a crash. Now you if you are drilling a hole and then are done with an operation and then going to other operation and the machine is not resetting back to C0 when it A0 then yes that can be done. That was not the question you asked. You asked the above and you got the answer you got. Put up some example files and code and get very specific in your details and someone can then get very specific in their answer or answers. Ask what Statue you are going see in Europe and expect to get some confusion or not even an answer, because just about everyone I know cannot read someone else's mind. 

 

Grumpy old troll saying have a great day.

I didn't expect anything coming into this page except a bit of help and an answer to a question, not a tour of Europe, and or a sarcastic remark or comment. yes I can be more specific, that should have been

your reply not some lame line of crap, but there is no need  now, I came up with a answer and solution that fits my needs just fine.

 

Go back under your bridge troll with all your friends.

 

 

 

Good Day.
