Need to decrease speed on lead out

[LNabor]

Hello

 

I program for a abrasive waterjet and when my toolpath comes to the lead out the water stream jumps into the lead in than has been cut already.

 

So I need a c-hook, or something that will automaticly slow down the feedrate when coming back to the starting point.

What type of machine is it?

Which control?

It can be done in the post.

Search for pfr in yout pst file and add the following.

 

code:

---

 exitfeedcounter : 0

 

 

pfr # Feedrate W/O Negative Feedrates

if fr > 0, fr

if exitfeedcounter = 1, exitfeedcounter = exitfeedcounter + 1

if cend = 1, exitfeedcounter = 1

if exitfeedcounter = 2, "F2." #change F2 to desired feed

if exitfeedcounter = 2, exitfeedcounter = 0

Sorry it is a flow machine and we had a special post made to write the flow code..

So the pst is not typical.

This also applies to router machines with the table saw attachment... Please explain then how you accelerate on the lead in, constant feed on contoour and then slow down on lead out

In the operations manager right click on the nci file and it will bring up the toolpath editor, select the point at which you want to change the feedrate, click edit, edit point, you will then be in the edit point parameters page with all kinds of options.

Hope this helps!
