Hi there.
We apologize for my poor English. Hyundai Kia machine is a skt 400 LMC. What is the M code to open the Steady rest? And where the machine saves the current position of tailstock and steady rest (after selecting the M83 head after the tailstock is not going where it is needed, the same in the case of steady rest. I hope that someone will understand my story and help.

Hallo,
try it with
M73 : HYD. REST CLAMP
M74 : HYD. REST UNCLAMP
M77 : HYD. REST PIN IN
M78 : HYD. REST PIN OUT
if this is not correct give me a feedback and i will check it as this is from a SKT400M and this should be almost the same

and the Tailstock Positioning parameter should be in the macro variable.
you need to go to (Keyboard) Offset and press at the screen to the right side until you get a softkey called Macro. Now search for Macro parameter 503 (or just use page down).


Also you can check the correct Parameter easily by checking to which position your tailstock moves and double check it with parameter 503. if this value is the same like your Machine position value, this parameter the correct one. as i´m not 100% sure.
But in it was 100% some of the 500 parameter


O9020(M83 T/S PIN UP)
IF[#1008EQ1]GOTO100; (G55.0→Y4.2 (HYD.REST PIN-UP SOL ON)이면 N100으로)
IF[#1000EQ1]GOTO10; (G54.0→Y7.0 (T/S PIN-IN SOL ON)이면 N10으로)
#1=#4001; (G00/G01/G02/G03 SAVE)
#2=#4006; (G20 inch / G21 metric SAVE)
#3=#4109; (F CODE SAVE)
G21; (INCH DATA INPUT)
#150=#5021; (X축 현재 기계좌표)
#151=#5022; (Z축 현재 기계좌표)
#152=#502; (PIN-DOWN시의 X축 기계좌표) <--
#153=#503; (PIN-DOWN시의 Z축 기계좌표) <--this one i mean

Hi

Thank you very much for your help. I have a problem if the program inserts the speed limit "G50 S650 ', the spindle does not reach the workpiece axis of rotation only about 550th This only happens when you run the program. With MDI, no problem.

[cadman@teluspla]

G50 S650 will limit the RPM to a max of 650 RPM so no mater what you program your G96 as the machine will only go to 650
You need to raise the G50 limit to whatever is safe for your setup
Best regards
Chris

My friend does not understand, or I do not understand you.

Why is giving the machine a restriction to 650 rpm (G50 S650), the machine accepts up to 550 rpm limit?

[khaot183]

I think it is because of the Gearbox.(Parameter)
as Low gear is from 0-550 rpm (i thought 500rpm) and you are during cuttingcycle it will not switch to second gear which is from 550-3000RPM

and as far as i know that´s why it is just possible to run up to 550rpm and not to 650rpm

otherwise the pindle would stop, change gear and run again, and this wouldn´t be what you want, during cutting....


hope this makes the situation more understandable

try it when you call M3S600 and G50SXXX and this should work correctly

[cadman@teluspla]

Good point khaot183
Also
Are you programing G96 or G97?
What is the diameter being cut?

[mateu5]

G96 is programmed, when planning the machine should reach more of the limitations and reaches about 100 less than is given. In MDI mode, everything works as it should. When programming G97 is also good.
