G100+ G-Codes: OEM-Specific Functions and Advanced CNC Control
cnccodeG100+ G-Codes: OEM-Specific Functions and Advanced CNC Control Standard G-codes (G00–G99) cover basic CNC motions, drilling, tool changes, and feedrate modes. But many CNC controllers also support G100+ series codes — these are custom or extended G-codes, often OEM-specific or ...
G98 vs G99: Controlling Return Positions in CNC Canned Cycles
cnccodeG98 vs G99: Controlling Return Positions in CNC Canned Cycles When using canned cycles like G81, G83, or G84, the CNC machine needs to know where to return after completing a drilling move. That’s where G98 and G99 come in. ...
G96 vs G97: Constant Surface Speed vs Fixed RPM in CNC Turning
cnccodeG96 vs G97: Constant Surface Speed vs Fixed RPM in CNC Turning In CNC turning, spindle speed directly affects surface finish, tool wear, and chip control. G96 and G97 are two G-codes that define how the spindle speed is determined: ...
G95 G-Code Explained: Feed Per Revolution for Precise Turning and Threading
cnccodeG95 G-Code Explained: Feed Per Revolution for Precise Turning and Threading G95 is a G-code that changes the way feedrate is interpreted in CNC programs. Instead of units per minute (like in G94), it uses units per spindle revolution — ...
