Lathe macro program mazak bearing Roller

[taperedbearings]

I help need with creating a simple macro to turn a bearing roller simple cylinder with a hole, and tapered roller with a radius face. i have a g code program without the macros variables i need to add some loops and logic to it to use the #500 variables please help. i've wrote several for grinders just not for lathes.

here is the code i have to work with

Joe,
I got your PM and I figured we can just work this out here so anyone can chime in.

First off the code looks pretty basic for rough, and finish profile. So my question is what needs to be changed? IOW why do you feel you need variables? Are you going to be doing different diameters were you want a variable to offset them? Or are you just looking to consolidate the rough and finish pass?

I did notice that you can use a canned cycle to do the drilling. You are wanting to peck drill the part. I don’t know the exact syntax is on your Mazak but it should look something like this.

N40 T1212.01 G96 S80 M3 R1 M8
G0X0Z.1
G83Z-2.49322R0Q.2
G30U0
G30W0
This will drill to your depth of 2.49322 with a pick of .2 and return to Z0 after every pick.

We just need some more info on what you want to do from a turning standpoint and we can go from there.

Stevo,

My goal

1. to have taper angle adjustablity form 0 to 7 degrees
2. corner radiuses at each end of the part to be adjustable radius values the same at each side not different.
3. the length of the part to be adjustable
4. on a tpaered roller for a bearing the large face of the roller is a large radius segment in thios part it is a 22" radius from the center line blending to the corner radius of .130 this 22" radius is another variable
5. the spot face and drill is not a value i would need variable since it is driven by the tool being used
6.the diameter at the large end sharp point, or the largest measurable diameter at the radius blend to the taper.

i'm using a bar feeder on a qt250msy mazak machine roughing and finishing tools will be the same as in the program i posted

My plan was to use the #500 and above variables and label them at the using the bit parameters to make it easier for the operator

the reason for this is to remove the smartcam and programmer.
to go from print to operater to part. no external programming.

thank you for your time. if you have any bearing needs fluid film or rolling element anything special of standard i can help getting them or making them. i have capablities from 1" to 25 feet and resources to every major manufactor and speciality. i would be glad to help anyone. i have in house heat treating flame, induction, case, and thru harden.

i can send a pdf. print of the part if you send me a email

Jdp@kingsbury.com

[stevo1]

That would help a lot for the calculation lines. I sent you an email. If it is nothing proprietary you can also attach the pdf to your post here.

how do i attach a pdf. here?

[stevo1]

Once you have typed your message in the box click the "Go Advanced". It will then show you the preview of your post. Click on the paper clip for attachments. It will then show you the file types you can attach and the size limit of the file. Click Browse, then open your file and then click upload. You will see it attach. Then you can close the window. I usually click on preview post again just to double check to make sure it attached.

Ok I have been working on this on and off and I have a few questions for you. First off is there a specific diameter that you must achieve at all times. Because of the fact you want to have adjustability in the height and angle this is going to change your TSC at the top and is also going to change the GL diameters. The calculations can be written to spin around the diameter of 1.277 @ 1.0” down if needed.

This is going to take some work as there are going to be a lot of calculations to achieve what you are looking to do(radius onto angle). I will write the calculation functions as I would for my machines but I do not know the proper syntax for the Mazak control using the macro functions.

Dale…..I notice you peaking in on this thread . I know you are probably already got this stewing in your mind if you don’t have it done already. Feel free to jump on in. This one is going to be fun.

the math is the same as fanuc, variables the same.

I still need to know how you want the part calculated. IOW what do you need for dimensions (diameter)? Do you want the diameter to be dictated by the length and the angle that you specify?? Or do you want to maintain a specific diameter 1”down the part regardless of the length and angle??

Stevo

[taperedbearings]

the diameter can drive the angle it can be from the sharp corners at each end, or 1" down and small end sharp corner, the angle doesn't need to be input since the diameters will drive the angle anyhow. just maybe a output value from the diameters to tell use the angle, or 1" diameter down and the angle will genterate the large sharp end diameter and small sharp end diameter.
