[Emc-users] 5 axis g-code

2011-06-03 Thread Viesturs Lācis
Hello, gentlemen! I would like to ask, if anyone can suggest me a way to generate a g-code for a single-time situation: The part consists of 3 pieces of tubes - 2 of them need to be welded to main piece. What I need is to get a g-code that describes the intersection lines of each 2 tube pieces. I

I don't know the geometry but if it is a straight tube intersecting a straight tube the motion would be three axis motion. It may be tilted to some angle but the machine motion would be 3 axis motion. On Fri, Jun 3, 2011 at 2:41 PM, Viesturs Lācis viesturs.la...@gmail.comwrote: Hello,

Missing from the question is the actuals joins needed, angles and types of cut, are the pipe sizes the same etc. and then there are the moves for welding which are another problem due to welding constraints. Dave Caroline

Since you are welding them anyway... you might want to look at this. It generates 2 axis Gcode to do a tube to tube coped joint and it looks pretty simple. *http://www.metalgeek.com/static/cope.pcgi *Dave On 6/3/2011 3:41 PM, Viesturs La-cis wrote: Hello, gentlemen! I would like to ask,
