Lathe B axis question

[dan m]

I put a file on the ftp site called baxis it's in the MCX2_Files folder. what I am tring to do is turn the b axis on the lathe (which i have never done ) to the proper angle and just cut the chamfer on the holes. I think I am haveing a problem creating the proper construction plain. any help would be greatly appreciated.

[crazy^millman]

Yes you are creating the wrong C-plane for this operation. I do not know your machine but if it like the Integrex you can not go very far below center line so not only do you need to get the B axis correct you need to get the C axis to index to the next place everytime.

 

Step by step is how I do this on the Integrex.

 

1: go to the right view this will be your 1st index and should put the B axis at the right direction which should be B0 is that is normal for your machine if down is normal the I would think it would B-90. Ok now you have your B axis in the correct place to chamfer this hole.

 

2a: Use Transform and rotate the operation to the other places so you have 2 operations to do the whole thing complete. Now I have seen posts want move to the X,Y places to do this and if this happens go to 2b. if not you are good.

 

2b: Make a C-plane for each hole and you must do this in right if you try to rotate your C-planes from the top View it does not work and will keep giving you Front or Back and not change like it should so go to right and do it this way. Ok so go to plane/rotate planes/ then in the Z box put in 60. Now you will get the new C-plane box and name that what ever you choose. Me I like 60 Deg and then you will do the same for each hole. Then copy your operation and then in each copy just use that new C-lane for each index and all should post correct for you.

 

Now MpLfan will not give you a B axis, but here is code from our Integrex Post using Transform:

[crazy^millman]

I have also put a file on the FTP called Baxis crazy.mcx and see if that also helps answers some questions.

[dan m]

Ron thanks for the help. that will work just fine I was just wondering how you would do it cocking the b axis 13 degress and doing it. The only reason i wanted to do it that way is because we have only worked at b-90 and b0 after having the machine 2 years i figured i would try somthing different manly tring to learn somthing new. thanks for all your help.

[crazy^millman]

Ok well you did not have the holes at 13 degree and that edge is conical so was not thinking along those lines. I have a new file with the holes at 13deg s oyou get a better idea how to do this. It is called Baxis Crazy 13.mcx.

Thanks Ron that is exactly what I want. The question I have is how did you create the construction plan in the wcs? Did you need to select the line thru the hole and the edge of the circle?

[crazy^millman]

What you do it use the Hole Axis chook to create the arc and lines. Then you use the line as your Cplane. To od this you go to planes/planes by normal. Then a box will come up with an arrows to choose which C-Plane you want.(Thing to remember here is that you are using C-planes not WCS even though when you hit Planes all of the standard views have (WCS next to them) I commented many times this should no be, but I am crazy). Ok now remember you want Z facing you and X pointing in a good direction which if you think about how you are looking at the part if oyu were looking at the View X should be facing the same as if you were in the Top View. Sometimes when you use Normal for the C-plane selection it is off in X so then you rotate that C-plane around Z to the way you want it facing and that should take car of any index problems if your index comes out below X0. Hope that was clear enough to understand and follow.

Thanks again Ron this makes perfect sense. I’m going to give it a try right now. Once again you are a wealth of knowledge.
