We have a large bridge mill that can mount a 90 degree head at angles but it does not have this function in the manual jog mode. The only way to do it, if you have a tool in a hole is in MDI. you command a G68 coordinate rotation to make the work plane at the angle of the head. Then make a incremental move (G91) in Z plus direction to move the tool out of the hole. It is a little nerve racking way to do it. But it's the only way.

@@EdgePrecision the universal head we got is a manually adjusted one. It kinda sucks compared to the powered ones because the powered ones can be changed automatically like a tool van but this has to be taken on and off by hand and then a setup process across multiple pages to get everything happy. Then it has 2 points of rotation which have to be indicated in one at a time using a test bar to get the angle accurately set. The powered ones do this all automatically giving the machine 5 axis capability and have an accuracy of .001 of a degree. We wanted the powered one but the control that this machine was built with doesn't have enough inputs to run the head so it couldn't be added on.

I'm here. I've just been working on jobs that I have already made videos on or can't make them on. Also been working on some Mexico stuff.

It should be absolutely accurate because this is the way the machine moves. It would be nice to have this function on a manual type of machine. Think about it no more guessing. just set the B angle and jog the machine to turn or bore a taper. Or drill holes at angles. The only thing that would be nice is a constant feed function in either Tx or Tz in the manual mode. My Mazak will do that in the normal X,Y,Z axis but not in these selections, or the B and C axis. Also as on the Mazak Integrex it is also updating the position display as you rotate the B axis. So if you want to say drill a hole at an angle a certain distance from the end of the part, its pretty easy to know where you are. Or turn a certain size chamfer.

I'm not really sure how this could be done with fixed gear ratios? They could work for one position of the B axis but it continually changes as the angle of the B axis changes.

@Edge Precision variable differential gearboxes. You would have to calculate the proper input cam ratios, but has been done with mechanical gantry systems long before servos where common place to provide "linear moves" as apposed to "dog leg" moves while traveling between limit switches. Let's say b, z, and x axis are all coupled. If the b axis is at 0 degrees (normal to z) then the variable differentials would be at 1:1 and input to the handles would be normal. As b axis tilts, the rotation of the b axis would have to input to 3 seperat variable differentials at the same time. 2 of the gearboxes would correct input from the handles to make the "linear vector" move. The 3rd gearbox would tie the Z and X axis handles together and cause them to move simultaneously to a varying degree based on the input cam reference from the b axis. There would have to be a couple of "engage/disengage" clutches to go from "linear" to "vector" moves, but is completely possible to do. The movement mechanism would likely resemble the backside of an old multi-spindle screw machine with shafts and gears everywhere. One could do it with just one variable differential between the x and z axis handles, but the "fine tuning" of the final motion resolution would likely be less than adequate for typical machining types of motion.

¡Gracias y tú también!

I think you have your G codes a little mixed up. G17,18,19 are for selecting the plane of circular interpolation. The normal (Usually default) is G17 the X,Y plane. G18 the XZ plane and G19 the Y,Z plane. What you may be referring to is G68 work coordinate rotation. That one transforms the machines axis to the new rotation. And yes in the auto mode all CNC machines will do that if they have the option in the control. It's pretty standard. You can combine the two but first you would have to rotate the work coordinate then specify the circular interpolation plane if it is different than the one already enabled.

I am working on a video on some very small parts on the Mazak. I just haven't had the right jobs for videos. They are either repeat jobs I have already done a video on or a job I cant do a video on. But I should have this video out this week. Thanks!

@@EdgePrecision I'm making a long 50 inch shaft with a single turn 31.5 inches long +0/-.002 Was asked how I ensure size. shared your video of its bore boring technique you use similar to what I do. And saw you hand posted in awhile I enjoy your content very smart man

I don’t use Mazatrol for anything on this machine except for boring soft jaws. I prefer to use my cam software because it can do things the Mazatrol can’t. Also the simulation is way better then the one on this machines control (this may be better on newer Mazak controles). The Mazatrol is excelente on normal lathe work on a 2 axis lathe. But for milling it’s a little difficult for anything that’s not simple things.

Yes G68 or 69 does do this in the auto mode or maybe if you commanded it in MDI and didn't hit reset. This sort of depends on the machine. My Mitsubishi horizontal will do such things. I have a video where I demonstrate manual jogging a rigid tapping cycle that way on it. But a lot of machines wont carry the MDI command like that into the manual mode. I know on the Mazak if I stop the machine to do a manual tool point save in the auto mode with a work plane rotation enabled it jogs like normal (Not rotated). But it will still jog with the Tx and Tz like I show in this video in the middle of a program.

@Edge Precision u are the best machinist on utube in my opinion, I used to operate a puma 5 axis when they first got to the states!U rarely find an excellent mill/lathe machinist, but u also do grinding and everything under the sun.God bless how was Mexico?

@@gilbertotejeda4167 La ultima vez estuvo bien. Nos vamos a Mexico el veinte de abril otra vez, Hasta el treinta. He estado practicar mi espanol para hablar con gente en Mexico.

@@EdgePrecision Tu Español es perfecto yo tambien quisiera visitar Mexico tambien mis Padres son de Guadalajara. Que tengas buen viaje y que Dios te bendiga!

You should be able to go into position screen, press Z or X and press origin and should set your operator position to wherever you currently are

Therefore no one benefits until they get their big payday.

Or the patent expires.

That will cost money and time to do

That wouldn’t stop them 😂
