Variable speed

[machinebob1]

Haas lathes have a SSV . Does Okuma have it to. I've got a LB 3000 EX

hi you may find these functions available as an option :
... with manual parameter edit :
...... for turning : harmonic spindle speed control ( hssc )
...... for threading : i don't remember exactly
... using microphone or built-in senzors to suggest and/or to auto-adjust the spindle speed : pls check navi-lg & navi-tg @ this link : https://www.okuma.eu/technologies/in...achining-navi/

please, would you share some applications that require ssv ? kindly

You must look OSP Software Management Data Card for optional specifications.
o sign means cnc have this spec
- sign means cnc don't have

Thank you. but how do I get to OSP Software Management Data Card.
Sorry for the stupid question.

try c:\ops-p\ospmngcd.cnc

Yepper I found it and my machine has it in the software. do you happen to know what M-codes are used for this. I called Gosiger and waiting for a call back, nobody seems to know right off the bat.

• Amplitude (Q) – the percentage amount of variation in the RPM
• Interval time (R) – how long we stay at the peak or valley of RPM change
• Speed variation cycle (P) – the pitch of the RPM variation

-- Parameters
The following parameters are added to allow the settings of amplitude (Q), cycle (P), and interval timer (R).

(1) Spindle speed variation amplitude (Q)
Sets an amplitude of spindle speed variation.
Parameter word No.114
Setup unit 1[%]
Setup range 0 to 100
Default value 0

(2) Spindle speed variation cycle (P)
Sets a cycle of spindle speed variation.
Parameter word No.115
Setup unit 0.1[sec]
Setup range 0 to 255
Default value 0

(3) Interval timer (R)
Sets an interval timer.
Parameter word No.116
Setup unit 0.1[sec]
Setup range 0 to 125
Default value 0


--System Variables
The following system variables are added to allow the reading and writing of the above parameter data.

VFLTQ: Spindle speed variation amplitude (Q)
VFLTP: Spindle speed variation cycle (P)
VFLTR: Interval timer (R)


M695: Spindle speed variation control ON
M694: Spindle speed variation control OFF

oau kurmay, you are such a genius

is it true that this function delivers long parts without a tailstock ? like 10 - 20D ?


i am not sure, maybe navy is responsible for that ... i don't have functions

[deadlykitten]

maybe this #42.2 interlock for spindle speed variation will help; pls check attached

i have no clue what it does ( maybe it helps, maybe it will burn the spindle ); i only encountered it during a wild trip / kindly
