Computer Programming-Related Features of Custom Macro

Custom macro is an interpreter-based language, meaning that all CNC G code and custom macro commands are executed as the CNC comes across them.

5 Reasons Why You Should Know How to Write Custom Macros

Custom macros enhance what can be done in G-code programs, giving users the ability to code operations that were previously not possible.


Help Operators Understand Sizing Adjustments

Even when CNCs are equipped with automatic post-process gaging systems, there are always a few important adjustments that must be done manually. Don’t take operators understanding these adjustments for granted.

The Best Point of Reference for Program Zero Assignment Entries

Correctly specified program zero assignment and coordinate position values enable the CNC to determine how far to move the cutting tool during each positioning motion.

Higbee threads provide a full thread form at the very start of the thread. The sharp edge is removed during the machining process.

3 Mistakes That Cause CNC Programs to Fail

Despite enhancements to manufacturing technology, there are still issues today that can cause programs to fail. These failures can cause lost time, scrapped parts, damaged machines and even injured operators.

A Spiral Milling Custom Macro Using Constant Contouring Feedrate

Helical milling or “spiral” milling are helpful when machining a circular pocket that is much larger than the milling cutter diameter.
