G-Code to Calculate Chip Load: Forward, Reverse, and Macro
Chip load connects tool data to the F word: compute feed forward from chip load, audit any program in reverse, or let macro variables do it in the code.

Parametric Programming vs Standard G-Code: When to Use Each
Standard G-code states fixed coordinates; parametric programming computes them from variables. One is a recipe with exact amounts, the other a recipe with formulas.

How to Program a Part Counter in G-Code: Three Working Builds
A G-code part counter is a persistent variable incremented per cycle, plus a decision at a target: stop, message, or pause. Three builds from simple to smart.

Macro Programming for a Family of Parts: One Program, N Sizes
Family-of-parts macro programming replaces N near-identical programs with one parameterized master: the structure, the variable sheet, and the prove-out rules.

CNC Turning Macro Programming Examples (Macro B)
Macro programming adds variables, loops, and logic to turning G-code. Two worked examples: a parametric grooving loop and a parts counter, plus the syntax map.

G-Code Variables: #100 vs #500 Series Differences
Macro variables differ by lifespan: #100-series commons clear at power-off, #500-series survive it, and locals #1-#33 live only inside a call. Here is the map.
