Right Angle Head Machine Setup

[Justin Beebe at Folsom Tool]

I have to mill a counterbore with a right angle head on our Makino horizontal mill. It's the counterbore going through the boss on the left side of the part. The axis of the counterbore runs parallel to the X-axis of the machine and the tool will be interpolating in the YZ plane. By using a router post I was able to post some code that looks good. My question is how do set the tool length offset for the tool in the angle head so the machine cuts at the correct Z level. I was thinking to use our tool presetter and set it to the centerline of the tool. I don't know what common practice is. Also how do I let the machine know how far out the tool is sticking out of the angle head along the X-axis so I can control the start and finish depth of the counterbore. Can I define this in the tool definition?

 

Thanks for the help. I have never used and angle head before

 

Here is a pick of what I'm trying to do.

Justin, in the VMC I would set the Z height to the center of the tool then set a work offset specific to the c-bore using the center of the bore as my X,Z or Y,Z origin, in Mcam set a custom toolplane with the origin at the center of the bore same as it is out on the machine.

We use a special post for our 90 deg. head work and like mentioned above we create a work plane from that side and a regular tool length is set. the post takes care of everything else of flipping it to X,Z or Y,Z and tool length. All of our 90 deg. work is done on one of our larger machines and we rotate the part so the work being done is on the left side. Probably don't help you a lot, but it is hw we do it.

Ok thanks for the help.
