Multiple Post Processor Questions (Drilling, Max Feed, Max Note length)

[matthew_metzingerRD8F6]

Good morning.

I'm in PM 2024, and have a few questions about modifying my post processor, for a Haas.

When I do drilling, I am getting hundreds of lines of code, for the drilling, that would normally say be G83.

When I use say Break Chip cycle type, with Drilling Cycle output checked ON in the operation, and go and post it, also with Drilling Cycle Output checked ON in the NC Program posting dialogue, I get lines and lines and lines of code for the drilling moves.

Is there something in the Post that I can set to get Drilling Cycle output?

Is there a way in the post processor to limit the maximum output feedrate?

The Haas I have maxes out at I believe 400ipm, and I keep missing feedrates from older files, that have 750ipm feeds.  I'm constantly having to go back, fix feeds, repost, etc. etc. etc...

Is there a way in the post processor to "break" comment lines, that are too long, into multiple lines of comments?

The Haas I have is erroring out on Operation Descriptions that are too long, but I personally want or need very descriptive Operation naming.

If it can't break these into multiple lines, is there a way to eliminate comment lines that are over a certain length, from being output?

Thank you all for the help

For max feed. 

Here is one way using a, if feed is greater the 500 then say the feed is 500, this is using if end statements.

On help in post processer utility, click on contents, go to tab search, search operators, click on Assigning expressions to parameters.

you should see a topic based on this. (probably the right way to do it)

Feed Rate = max ( %p(Feed Rate)%, 100 )

It sounds like you need to add or configure Break chip setup to output G73 cycle

Very nice, thank you both for your responses.

I will try both of these out and see if I can get it to work.

Thank you both again.

I appreciate the help...

For max feedrates, there is a Max feed setting in the post and when you set it, it will automatically reduce the feedrate to the max, without having to add extra logic to the post. 

Some posts have a settings turned on to break the connection when the feed is over the Max rate, so we just need to check that setting and turn it to a Warning instead.

Sean, thank you.  That looks like it will do the trick.  I really appreciate your help.

[matthew_metzingerRD8F6]

Sean, that worked perfectly.

Thank you for the help.

[matthew_metzingerRD8F6]

Kevin, that did it for the drilling output.

Thank you for your help...

If you only want it to be used with a certain toolpath style, you can look at more if end statements like 

if (%p(Toolpath Type)%=="DRILLING")

Very nice.  Thank you rich4.
