5 Axis Tool Cutting Into Part

Recommended Posts

Hi Guys,

 

I`m having problems with Mastercam not compensating for the tool diameter in a morph toolpath. I would generally program the part with a ball which works easily, but this time need to use a large bull style cutter as the parts are over 9.5m long. I`ve included a simplified sample file with a small section of the part, i can program it 3+2 but was hoping to do it multi and hoping its just something simple im overlooking. Any help would be greatly appreciated.

Thank you for the advice guys, so far i have tried using a standard bull, flat and barrel tool definition. Tried run tool auto and at radius. Tried offsetting a surface, making it drive and the tool face check geo all with no luck. The other thing i`ve found is when making a triangular mesh rough toolpath setting the tool axis control to from chain the only tool that will tilt as it`s ment to is a ball, endmills stay in 3 axis.

Sorry it's taken so long to get back, I got slammed but thank you Ajmer I would never have thought to look at the extend to infinity as I don't really understand it, generally just turn collision control off and sort it through verify and adjusting toolpaths. Being routers more 3+2 than full 5 axis. I cleaned the weird move up, not perfect but much nicer can share that next week if people are interested

Extend to infinity pretty much what it says it is - take your tool and imagine it is as long as infinity, going back into your machine.  
It is useful if you have a cut angle that you know might run your head into something - you can add a tilt /avoidance strategy. 

Also very useful to control machines that don't have a physical tool (like spraying or blasting)
