CNC cutter compensation visualizer
Visualize G41, G42, and G40 cutter compensation on CNC outside profiles and inside pockets, with direction-aware left-right guidance, lead-in checks, and live tool-center offsets.
Specific calculators, planners, and explainers for jobs that usually get buried in forums.

Machining and CNC tools
Visualizers and reference tools for CNC cycles, cutter compensation, lathe gearing, and machine-setup decisions.
This cluster groups the site's machine-shop pages into one branch for people working through G-code motion, toolpath side selection, or change-gear threading setup instead of bouncing between isolated pages.
Tools in this cluster
CNC drilling cycle visualizer
Visualize CNC drilling canned cycles like G81, G82, G73, and G83 with live return-mode timing, peck stages, dwell, retract behavior, and per-hole cycle estimates in metric or imperial units.
Dividing head indexing planner
Plan dividing-head indexing for gears, flats, bolt circles, and flutes using your worm ratio, plate circles, and direct-index plate, with exact direct/simple/compound setups plus approximation warnings when an exact count is unavailable.
Lathe change gear explorer
Search simple and compound lathe change-gear trains for metric or imperial threading, with actual pitch results, error drift, and transposing-gear guidance.
Recent launch notes
Launched a dividing head indexing planner for hole-circle choice, compound indexing, and exact-vs-approximate setups
Added a hobby-machining indexing planner that turns a dividing-head ratio and plate circles into direct, simple, and compound indexing setups, plus approximation warnings when an exact count is not available.
Launched a CNC cutter compensation visualizer for G41, G42, lead-ins, and left-right confusion
Added an interactive CNC cutter compensation visualizer that shows how G41, G42, and G40 move the tool centerline on outside profiles and inside pockets, with direction-aware guidance and lead-in checks.
Launched a CNC drilling cycle visualizer for G81, G82, G73, and G83 timing, retracts, and peck strategy
Added a CNC drilling-cycle visualizer that simulates G81, G82, G73, and G83 canned cycles with return-mode timing, peck stages, a Z-vs-time chart, and per-hole cycle estimates in metric or imperial units.
