CNC Feeds & Speeds vs CNC · G

Stop breaking bits and burning material from guessed settings. CNC Feeds & Speeds is a workshop assistant for hobby CNC users who want safe starting points—and a personal library that gets smarter with every cut. Whether you run a Shapeoko, MPCNC, Onefinity, LongMill, PrintNC, or another desktop router, this app helps you dial in RPM, feed rate, plunge rate, depth per pass, and stepover before you hit Start in your CAM software. CONSERVATIVE RECOMMENDATIONS YOU CAN TRUST • Step-by-step wizard: pick your machine, tool bit, material, and operation • Settings biased toward safety—not maximum aggression • Respects your machine’s RPM, feed, and rigidity limits • Clear confidence labels so you know what’s calculated vs. tested • Metric and imperial units throughout YOUR PERSONAL CUTTING LIBRARY • Save recipes with search, filters, and favorites • Organize machines, endmills, and materials in dedicated libraries • Quick dashboard for recent recipes and test cuts • Export recipes and test cuts as JSON or CSV LEARN FROM EVERY TEST CUT • Log actual settings, outcomes, and issue tags (chatter, burning, tear-out, and more) • Attach photos to remember what worked—and what didn’t • Build a searchable history that improves future recommendations WORKS IN THE SHOP, SYNCED AT HOME • Full offline use—read, calculate, and log without internet • iCloud sync keeps workspaces up to date across your devices • Share an entire workspace with a shop partner, spouse, or maker space • No separate account—uses your existing Apple ID BUILT FOR HOBBY CNC, NOT PRODUCTION FLOOR CNC Feeds & Speeds targets wood, plywood, MDF, acrylic, plastics, foam, and light aluminum on hobby routers and desktop CNC machines. Recommendations are starting points meant to be refined with test cuts—not a substitute for professional machining advice or CAM software. Perfect for makers who want fewer broken endmills, cleaner finishes, and a recipe book that travels with them from the garage to the bench. Questions or feedback? Use the contact option in Settings—we’d love to hear from fellow CNC hobbyists.
