How Major Brands Approach G-Code Ref

Not all tooling manufacturers publish their G-Code Ref the same way. While the underlying physics doesn't change, the recommended ranges, safety margins, and application guidance vary considerably across Iscar, Seco Tools, and Sumitomo Electric. Understanding these differences helps you make better tooling decisions.

Iscar

Takes a material-group-first approach with Ionbond-coated grades as default. Their application guides provide conservative starting values with wide adjustment bands. CoroPlus digital integration offers real-time G-Code Ref optimization via ToolGuide.

Seco Tools

Known for aggressive starting parameters — particularly in steel and cast iron. NOVO digital platform auto-adjusts G-Code Ref based on tool path engagement. Often the go-to reference for high-feed applications.

Sumitomo Electric

Pioneers of multi-directional G-Code Ref — their IQ series inserts thrive in turning profiles where engagement angle shifts continuously. Application-specific grades for ISO P/M/K with narrow, optimized G-Code Ref windows.

Key takeaway: Always default to your specific tool supplier's G-Code Ref charts. The differences between Iscar, Seco Tools, and Sumitomo Electric reflect different coating chemistries (Ionbond vs. in-house) and carbide substrate formulations. A Iscar parameter won't necessarily translate to a Seco Tools equivalent — even at the same ISO grade designation.

Common G-code commands for CNC milling and turning

G-codes control motion, coordinate systems, tool compensation, and canned cycles on CNC machines. This reference covers the most-used G-codes across Fanuc, Haas, Mazak, and Siemens controls. Most are standardised by ISO 6983 and RS-274; differences are noted.

Frequently asked questions

Are G-codes the same on all CNC machines?

Most G-codes are standard across Fanuc, Haas, Mitsubishi, and Siemens controls for basic functions (G00, G01, G02, G03, G17-G21, G40-G42, G54-G59, G90-G91). Canned cycles (G81-G89) are largely standard. Differences appear in advanced functions: probing cycles, polar coordinates, thread repair, and high-speed machining modes vary by control brand.

What is the difference between G-code and M-code?

G-codes control motion and geometry (positioning, feed, coordinates, compensation). M-codes control machine functions: M03 (spindle on CW), M04 (spindle on CCW), M05 (spindle stop), M08 (coolant on), M09 (coolant off), M30 (program end and rewind), M06 (tool change). Think of G for geometry, M for machine.

Can I use the same G-code program on a mill and a lathe?

No. Milling G-codes use X, Y, Z coordinates in a Cartesian system. Turning G-codes use X (diameter), Z (length) with a different coordinate system. Lathe-specific codes: G70 (finishing cycle), G71 (OD roughing cycle), G76 (threading cycle). Turning canned cycles are completely different from milling canned cycles.

How to use this G-Code Reference Guide

Use this reference to look up G-code meanings, syntax, and control-specific notes. G00-G03 cover 90% of motion commands. Canned cycles (G81-G89) handle drilling and tapping. G40-G42 and G43 are essential for precise tool compensation. Always verify G-code support on your specific machine control -- some older controls lack newer G-codes.
