I have Daewoo PUMA8 lathe machine with Fanuc 10T system.Sr. no. 370249
This m/c has got a problem of G92 . Example of part program as follows:
G96 S120 M03;
G0 X22.5 Z100.0;
In this program exicution spindle speed is clamp to 2000. But actually spindle rotates at maximum rpm of spindle in M41 ( low gear). and when x comes to nearer to 0 then it rotates at 4000 rpm which is max. rpm of spindle that spindle can rotate. If instead of G92 S2000;, G50 S2000; is used then spindle rotates with 20 rpm and remains at that20 rpm only. doesn't change.
One thing is noticed on m/c is all the spindle parameters(5600 ahead) are 0 in cnc parameter screen except 5602 -01100000. max. sp. rpm I thing are all given in data tables.
Also during the angle command e.g.
A250.0 X100.0 F0.1;
During exicution of this command only x axis movement happens it doesn't take simultaneously z movement to get the required angle.
Pls guide me in solving these two problems.
with best regards to everybody.
