Mazatrol T-1 QT20 ?'s Please help

[halfafinger]

Im new at the controls of this old girl and have been having a few problems.

Firstly with grooves: I wanted to put an o/d groove right next to where a taper finished today, no radius's on top or bottom, 5mm wide with a 4mm grooving tool, simple enough i thought. But when part was complete it was apparent that the groove had turned about 1mm into the taper in the 'z''positive direction, and the program was very specific, in that the start point of the groove was from the finish point of the taper. Is this something I can change in the parameters?

Second with grooves: Is there an easy way to program a tapered groove? eg; A 15 degree angle down to the starting point of the groove, a radius to break the edge, and then into the groove?

Third: Does anyone have a list of the parameters on a Mazatrol T-1 controller and a description of what they do? I have the operation manual but it is very vague in it's details of what some parameters do.

Your electrical circuit diagram book should have a default list if you do not have the actual machine params. They will get you in the ball park, but unless you can get the serial number specific params, the rest is up to you. Good luck too. I have been trying to get some T-1 stuff from Mazak, but have been getting nowhere.

don't forget this was a mitsubishi control, and the early mazatrol didn't really differ from the original. A lot of machine makers used this hardware including Leadwell and Traub for example. Maybe you can get an operators manual for one of these machines.

I believe I have a definition list of the parameters I could scan in if you want to PM me an email address.
With the exception of the OP para which are options.

The cause of groove being 1mm off might be caused by having nose rad on tool in TOOL Data

I usually use groove type "0"groove cycle, for 5mm groove with 4mm tool do 2 grooves with -1mm pitch. for instance if start of groove is 20 mm from Z0, finish side is 25mm, I would programme start point and finish point Z is 25.

If I need to radius OD corners I use BAR OUT(inverted). cut point Z 23, LIN to 24 with finish Rad of (eg)1. Lin minor size of grv to Z24.5

BAR OUT(inverted)CUT point Z 26. Lin to Z25 with finish rad 1. LIN to minor diameter of groove to Z24.5

This way of doing groove takes more programming but is much faster.

put tool shape "0" for grv tool and no corner rad.

You can use BAR OUT for doing taper down to groove as above, but I would plunge groove first.

If you did not get list of parameters I could send them as attachment if you send your email address.

I think that the OP parameters are the same on all my machines. Do you know how to enter them ?.

There are 8 digits of "0" or "1". If for instance there are 2 "1" on line type 2 as 9th digit, if 3 "1" on line type 3 as 9th digit.( I hope you know what I mean)

Hi murphyc1

Did you ever find out how to change the OP parameters in T1 control system?

I cant seem to change mine

Cheers Andrew

Hi Andycnc

If you have eg 3 of 1s (00010110) you type in 000101103 enter, if 2 of 1s type 2 at end.

Hi Murphyc1

Brilliant! That worked perfectly, thanks so much for your help. Im thinking maybe there is more wrong with my T1 QT10 now as the Z and X axis show position of *******. It also seems i have lost my programs, would you have any idea what i should do from here?

Thanks Andrew

Hi Murphyc1,

Thanks for the info it has been a great help. I am self taught on my QT10 T1 and until now i have made use of the tool set data from the previous owner. Now i had to clear that from the ***** problem i have lost that, any chance you could inform me on the best way to set the tools again??

Thanks again for your help

Regards Andrew

[murphyc1]

In tool data, if you have 80 deg tool is shape 1, 60 deg is shape 2, 55 deg is shape 3, 35 deg is shape 4. put corner rad .8 or .4 etc. CW for spindle clockwise, CCw or counter clockwise.

For tool setting machine diameter eg 50mm, got to tool number eg 1 type X 50,teach Enter, touch face with tool and teach Enter.

I will have to look at machine on Monday for cutting conditions etc.

Do you have square turret with tool numbers 11,12,13,14,21,22,23,24 etc or disc turret with tools 1 to 8?.

I am not sure if that is what you need, please let me know and I will try to help.

[Andycnc]

Thanks

Yes thats great info, i will try and program the tools over the next few days. I have the disc/drum type turret with tool no's 1-8. Would you have any idea where to find the batteries? Im thinking i should really replace those
