3+2 Axis Master cam Programing Methods

[kool]

Hello All,

 

I have done little 3+2 programing. Most of my experrance is on horizontal. I just started a new job and my new company just got 2 new 5 axis haas Trunion, so I want to learn more about 3+2 programing methods.

 

I been using center of rotation for all work offsets and draw my part in space as it is in machine. Set my WCS as top for all operation and move my Tool plane around. Keep all my Tool Plane orign at the center of rotation. Put your center of rotaion in G10 and off you go. But with this method if I use diffrent machine or fixture stack up, I have to move my part in mastercam and then repost it.

 

Is there any other method that can be used to program? Like instead of using the center of rotation for Tool Plane orign, Pick a corner on stock for orign at A0/B0. and let machine or mastercam find the part in diffrent rotation. That way if your are setting that part on diffrent machine with diffrent fixture stack up, operator can pick that corner for orign. I know some 5 axis machine have an option to compenste for center of ratation, I don't know what its called.

 

Please Share your thought and guide me into the right direction.

 

Thanks in advance.

If you write a macro to calculate the rotated distances in the machines, you can set up your part to use top WCS, move your Tool planes to get the correct rotations, and use your G10 values from Mastercam in your calculations. That is how we do it, except we have Okuma mills. Then you pull in the different values for your stack ups into the macro. I have this on 7 machines with 4 different controls without issues.

I suggest with the Haas trunnion find the gauge length between the two rotaries. then use this as your base point as at this monent the Haas does not support Dynamic Rotary Fixture offsets.

in my experience, Haas trunnions are made where the faceplate is 1/8" below center (or within a couple thou).

HRT210 for sure.

 

hey Kyle, pretty cool solution! got any code to share or a little more info?

Kyle,

 

Rotation Macro is what we do on our horizontal cell line here. we use one workoffset (G54....) for all the rotations, call the G10 line and G65 Macro line with every tool change or Rotation to calculate -x- and -z- and load those in the same work offsets. I can set my orign at any corner of the stock and this macro can calculate that location in diffrent tool plane from machine zero. But that is only one Axis rotation.

you think I could use the same Macro for 3+2 axis. where you setting you origin (-x-y-z-) for diffrent toolplane rotation.

 

I think that is little to much with using the one workoffset and calling the G10 and Macro with every rotation. Setup person can not make any adjusment if they need to so Machine stroke has to be really dialed in.

mkd,

Thanks, I will try and put something up to show what we do. It will be stripped of the parts that took me more than a few days to get done(I hope you understand).

 

kool,

Usually, I use the back end of the part set at Top/World origin, and create my tool planes from that.

In-House (Mr. McIntosh) put this beautiful post together.

Kyle,

 

Thanks for the info. We also have a Haas Trunion here and that sounds like just what we've been looking for. I figured it had to be done the way kool described in the top of this topic. You learn something new every day.
