Fixed cycle (Drilling)

Q: What does Mazak G-code G82 do?

G82 — Fixed cycle (Drilling) on the MAZATROL SmoothX control (INTEGREX e-670H). The feed rate will remain unchanged if either I or J(B) is omitted. X, Y, P, D, I, and/or J(B) can be omitted. Whether argument J or B is to be used depends on the value that has been set in bit 1 of Parameter F84 bit 1 = 1 : Argument J-command (argument J-command), setting a B-command will cause the table to rotate. Be care- ful in that case to ensure no interference between the workpiece and the tool. The feed rate will remain unchanged if either I or J(B) is omitted. X, Y, P, D, K, I, and/or J(B) can be omitted. If D is omitted or set to 0, the machine will operate according to the value of parameter F13. The alarm 809 ILLEGAL NUMBER INPUT will occur if Q is set to 0. Whether argument J or B is to be used depends on the value that has been set in bit 1 of Parameter F84 bit 1 = 1: Argument J-command (argume

Machine-specific. This G-code reference is specific to the Mazak INTEGREX e-670H / e-670H-S with the MAZATROL SmoothX control (EIA/ISO programming manual H747PB0030E). G-code availability depends on fitted options, and groups and behaviour differ between Mazak models and control generations — verify against the manual for your own machine before programming with any code.

What it does

The feed rate will remain unchanged if either I or J(B) is omitted. X, Y, P, D, I, and/or J(B) can be omitted. Whether argument J or B is to be used depends on the value that has been set in bit 1 of Parameter F84 bit 1 = 1 : Argument J-command (argument J-command), setting a B-command will cause the table to rotate. Be care- ful in that case to ensure no interference between the workpiece and the tool. The feed rate will remain unchanged if either I or J(B) is omitted. X, Y, P, D, K, I, and/or J(B) can be omitted. If D is omitted or set to 0, the machine will operate according to the value of parameter F13. The alarm 809 ILLEGAL NUMBER INPUT will occur if Q is set to 0. Whether argument J or B is to be used depends on the value that has been set in bit 1 of Parameter F84 bit 1 = 1: Argument J-command (argument J-command), setting a B-command will cause the table to rotate. Be careful in that case to ensure no interference between the workpiece and the tool. The feed rate is f only if the starting point of a cutting pass is within the range of i . […]

G82 is modal (group 09) — it stays in effect until another code of the same group replaces it.

Address words

t c : Dwell (in time or No. of revolutions) j 0 : Feed override ratio (%)
d 0 : Distance from R-point to the starting (b 0 )
point of cutting feed f 0 : Feed rate
i 0 : Feed override distance f 1 : Feed overridden f 1 = f 0 ×j 0 (b 0 )/100
Note: For a horizontal machining center, if the value of bit 1 of parameter F84 is 1
t z : Depth of cut per pass j 0 : Feed override ratio (%)
d 0 : Rapid motion stopping allowance (b 0 )
k 0 : Distance from R-point to the starting f 0 : Feed rate
point of cutting feed f 1 : Feed overridden f 1 = f 0 ×j 0 (b 0 )/100
i 0 : Feed override distance
