4th Axis HMC with right angle head

[K2csq7]

I have a large ring I will be laying down on our table which I need to drill 120 holes in from the top. I need to use a right angle head, move to X zero (center of rotation), come in with Z, and drill up and down in Y.

Can someone point me in the general direction I need to be? I have a Mpmaster generic 3/4 axis HMC machine def.(with aggregate head defined) with the mpmaster post.

I drew everything in the top plane and my Tplane is Front.

Thanks in advance, I think I am missing something pretty basic

I would just write a long hand custom y axis drill cycle and then call it with a [while do] statement

 

#100=1

WHILE[#100LE ]DO1 (LE = # OF HOLES)

 

bla bla bla (drilling)

 

G00B[#100* ](ADD ROTATION HERE IE:15 = 15DEG)

#100=#100+1

END1

Thanks Wes,

I was thinking that I might have to do something longhand...but only as a last resort. I have some time before this job comes along and was hoping to get it right with Mastercam? I have been able to use this post/ mach. def. combo to get good code for easy rotary work (i.e. face mill front of table, then right side, then....) using the different Tplanes. but I dont think I should have to create a new Tplane for all 120 holes....I am trying to use "rotary axis positioning, and am not sure this is the way to go??? Also I am not sure about how to use the right angle head, in the past I have used cimco to swap X,Y,and Z, then manually change the G17 to 18 or 19.... but I really want to learn how to do it the right way.

Do you have 3D rotate on your machine? What we do is activate this code using manual entry and then you program just like using G17.

 

Just my two cents.
