Drilling with B-axis in special angle on Integrex

I got a trouble.. Hope some of your guys can help me..

 

I'm trying to drill a serie of holes in an angle of 20 degrees on a Integrex.. But no matter how I try to place my WPC or anything, I can't make the Mastercam drill in other than 0 or 90 degree..

 

Is there something wrong with my machine definition or do I need multi axis drilling (which I don't have frown.gif ) or am I just completly on the wrong track here...

 

Feeling like I'm wasting here fighting with it, so any help would be appreciated..

Big Big no no here. Do not and I repeat do not use the WCS for indexing use only one WCS. I use only the WCS TOP, I then use C-Planes to index my head and my spindle. Click on the C-planes then rotate c-planes and this will be what you use for making the toolpath come out correctly. If you got a sample file send it my way and I will be glad to help you out. Please .Z2G with the post if it is a MCX file.

Ok you were using the Top WCS good job. You were using the Right C-plane again good job. The problem with the hole you sent me is that you have it below center that will not work on an Integrex. You need to program everything above center on an Integrex. The next thing is I would look to getting the add-on from Verisurf Linky: This has a tool called hole axis in it. This will create a vector or center line with point in the holes you are trying to do. The part you sent me is very simple for an Integrex, though it seems like a lot right now it is really not.

 

Let me see if I can explain this out a little. The Integrex as you know is a Mill/Turn machine it has very strong capabilities, but it also has some limitations. One of those being everything has to be done above center. It is how you go through your thought process that is going to make it hard ro easy. If you think you can only do half the part at a time when doing milling then it becomes easy, because you are only ever worried about half of the programming. Now you are asking well what do I do about the other half, you programming it just like you would the 1st half, expect in Mastercam you have to become very familiar with C-planes. Now Mastercam has some major bugs in other releases with regards to C-planes. I do not use X3 since we did not pay our Maintenance to go up to MU1 and X3 pretty much sucks I.M.H.O. with the exception of Verification which is all I use it for and of course Verisurf. (Sorry to Side track) So now C-planes. You need the right C-plane is also the Tool-Plane. Now why in the world we still have T-Planes and C-planes is beyond me. We do so yes you have to always update the T-plane and the C-plane when doing multi-axis work for any machining operation. So Right is going to be your C0, but if you are using the In-House post you have to remember Back is really C0 for facing upwards in the machine, but we face another big problem with Mastercam. The back and bottom C-plane are worth nothing for Multi-Axis work in Mastercam. So what I recommend anyone do that does Mill/Turn or 4 axis work to make a template file to build all 4th axis work or all Mill/Turn work from. In this file you need to create the correct Back and the Correct bottom C-plane. Set-up the correct Machine and Control Definition. Now when you do either everything is ready to go and you save trouble and problems down the road.

 

Making the template file is a easy process and keep back ups over in other places it is because in a hurry you will over write it. Now making the C-Planes correct is very easy. Make sure you are in Top C-Plane. In Mastercam you need to pick the button as shown.

 

RotatePlanes.jpg

 

Now that will bring up the rotate view Dialog box. Here you want to rotate about X. If you see in the picture below I have -90. in X I do not press enter I click with my mouse so I can see the AXIS combination indicator change. Now I recommend zoom out or in a little and it will clear up your screen. When it is like you want then hit the green check box like so:

 

C-PlaneRotate.png

 

This will then bring up the C-plane Dialog box and here you need to name it. I Call it BACK_CORRECT so I know what it is. Now when you go to do work with the Back plane everything is correct. You will need to repeat the same procedure for the bottom except you need to use 180 degree (No it does not matter -180 or 180 since it gets to the same place). Again making sure you are in Top C-Plane before starting. Save this file making sure you have the Correct Control Definition and Machine Definition. Now you have a template file.

 

OK now comes the next question the holes at the angle. Well this is where the Hole Axis comes in.

We use it create the vector then with C-plane normal we pick that Vector. I name hole by size, or Hole1 or something for me to remember it by. Now another bug with Mastercam. If you tell it not to set origin and want to use that C-plane at 0,0,0 so when you go to do a toolpath guess what you lose that as the one you wanted and one just like it at 0,0,0 now pops up as a number. The way around this is before you make a toolpath go into the WCS manger and make the values collected 0,0,0 and now that C-Plane can be used for the toolpath.

 

Now for the programming itself. Do 3 drilling operations at each C-Plane for 3 holes. Then use Transform Rotate, Copy Source Operations, Use Tool Plane, Then use 12 steps, Start at 30 deg and shift 30 deg. I would do this for all the tools you are planning to use and be done. The turning is easy so not going to cover that.

 

Then from there you are programming and getting what you need done. I emailed you the file with drill toolpaths put to it.

 

The next posting will be the NC code.

Ron,Thanks so much for sharing the info on this.Making those templates will make it so much easier for our mill/turn gramming.The tricks you show us on "how to" are greatly appreciated.Same goes for all the others that open our eyes as to how it's done and what to watch out for in MC.

Regards

Thanks alot for your help... It gave me a much deeper insight in how the lathe part of the Mastercam is working.. smile.gif

 

I have been working on different sizes of Integrex's for 4-5 years now, so I'm pretty familiar with it and the programming in the Mazatrol, but just wanted to try in Mastercam just to expand my knowlegde..

 

So again, thanks for your help.. It's really appreciated...
