## What is CNC Machining Calculator?

ChipDial brings everyday CNC and workshop calculations together in one offline reference tool.

Calculate spindle speed and feed rates, estimate tap-drill sizes, and work through common machining geometry. Switch between Metric and Imperial units, save useful calculations to local history and favorites, and recall saved calculation setups.

Built for machinists, CNC programmers, students and workshop users:
• Speeds and feeds, surface speed and turning feed
• Tap-drill estimates and drill/tap references
• Bolt circles, tapers, chamfers and other shop calculations
• Material removal rate and horsepower reference estimates
• Local history, favorites and saved-input recall

No registration, login, advertising or subscription is required. Calculations and saved records stay on your device.

Reference calculations only. Verify tooling data, material assumptions, machine limits and applicable standards before using a result in machining work.
