These advanced CNC machining calculators are designed for machinists, programmers, inspectors, setup technicians, and engineers who need more than basic calculations.

Unlike simple calculators, these pro tools combine multiple machining variables, visual guidance, aerospace material recommendations, shop tips, and real-world machining logic to help improve setup accuracy and machining efficiency.

Current Pro Tools

CNC Speeds & Feeds Calculator

Combined RPM, feed rate (IPM), cutting speed (SFM), IPT guidance, material recommendations, and surface finish suggestions in one professional machining tool.

Round Bar Size Calculator

Quickly determine minimum round bar size required for rectangular machining blanks with machining allowance support.

True Position Pro (MMC, LMC)

Advanced GD&T visual calculator with bonus tolerance analysis, pass/fail evaluation, and real inspection examples.

More Advanced Tools Coming Soon

• Bolt Circle Calculator
• Tap Drill Pro Calculator
• Surface Finish Visualizer
• Tool Life Estimator

• GD&T Visual Analysis Tools
• Material Removal Estimator
• Heat Treat Movement Estimator
• Aerospace Material Library

Built for real-world machining applications including CNC milling, turning, setup planning, roughing, finishing, aerospace machining, and GD&T inspection workflows.

Our goal is to simplify machining calculations with clean visual tools that are easier to use than traditional spreadsheet-style calculators.
