Simple Speeds is a speeds and feeds calculator for CNC routers, aimed at makers, hobbyists, and beginners—especially people using non-industrial, entry-level CNC machines. It is not general-purpose industrial machining software. Instead, it tries to automate the calculation of parameters such as spindle speed, feed rate, depth of cut, and width of cut, reducing the need for users to look up tables or understand concepts like chip thinning in depth.
Based on the information on the site, the product centers on a machine and router/spindle selector, material selector, metric/imperial unit switching, RPM calculation, feedrate calculation, and recommended DOC, WOC, or stepover values. Its differentiator is that it is optimized for specific CNC router models, rather than simply applying parameters intended for metalworking or industrial milling machines. The account system can remember machine information and frequently used input parameters. If users have a custom-built CNC router, they can also contact the team for help characterizing the machine and adding it to their account.
The website currently shows “Coming Soon” and “Get Early Access,” with no disclosed plans, pricing, free tier, or trial policy. The terms mention that prices may change and that purchase information and credit card details are transmitted securely, suggesting that an online paid checkout flow may be introduced in the future, though details are limited. The product appears to be delivered as a web service, with no mention of self-hosting. The FAQ explicitly describes it as a standalone calculator; results need to be entered manually into the user’s normal workflow. As such, it currently does not appear to offer CAD/CAM integration, an API, or developer capabilities.
The main advantages are its very clear positioning, optimization around non-industrial CNC routers, and an interface focused on intuitive inputs and clear results, making it beginner-friendly. It also supports unit switching and requests for custom machine profiles. The drawbacks are that the product is still at an early stage, the supported machine list is marked as pending updates, and its actual coverage is unclear. It also lacks team collaboration, permission management, security/compliance documentation, and third-party integrations, making it relatively weak for enterprise software scenarios.
Simple Speeds is best suited to individual makers, small workshops, educational users, and entry-level CNC users who want a quick reference for machining parameters. It is not ideal for teams that require industrial-grade machining validation, automatic CAM integration, or enterprise-level permission governance. The site does not provide information about access from China, and payment can only be inferred as potentially involving credit cards. If access or payment from mainland China is inconvenient, users may consider local CNC community spreadsheets, built-in parameter libraries in CAM software, or domestic CNC machining assistance tools as alternatives.
