MachLedger is an offline CNC workspace for machinists, programmers, technicians, students and workshop teams.
Calculate milling, turning, drilling, tapping, threading, metrology and production-planning values without an account or internet connection. Build a machine-aware setup card by selecting a machine, cutting tool and work material. Check pasted G-code for common setup risks before moving to machine-specific verification.
Key features:
• 81 CNC and workshop calculators
• Milling, turning, drilling and thread calculations
• Speeds, feeds, chip load, RPM and material-removal calculations
• ISO fits, tolerance stacks, true position and surface-finish tools
• Machine, cutting-tool and material profiles
• Offline setup cards with conservative starting values
• Static G-code preflight checks for unit mode, coordinate mode, work offsets and machine limits
• Offline job board and saved calculations
• PDF, CSV and JSON export
• Metric and imperial units
• TR, EU, US, CN and custom standards profiles
• English, Turkish, German and Simplified Chinese
• No account, advertising, analytics or cloud storage
MachLedger provides calculation and planning assistance. Cutting data must be verified against the cutting-tool manufacturer, work material, machine, workholding and responsible machinist. G-code preflight is not machine simulation.
