I lost the operation manual of Star SB-20R type G.In program G266A17.75W34.8S5500B2.20X-1.0Z150.0F0.05

I don't understand this part, can anyone help me?

Hi, these are the meanings for the letter in the G266 line,

A = Bar diameter
W = Part length
S = Spindle speed for cut off
B = Cut off insert width
X = Cut off end position
Z = Z1 start position (where the main spindle positions to machine a part)
F = Cut off feedrate

Hope this helps!
