About this app

CNC Quick Calculator is a CNC calculator built for fast shop-floor math. It combines a speeds and feeds calculator, feed rate calculator, surface speed calculator, RPM calculator, and chamfer calculator in one compact machining utility.

This app is designed for machinists, CNC operators, CNC programmers, trainees, and technical students who need quick setup calculations on mobile. Instead of a large reference suite, it focuses on the core formulas used repeatedly during setup and programming.

Main features
- Speeds and feeds calculator
- Feed rate calculator
- Surface speed calculator
- RPM calculator
- Chamfer calculator
- Metric and imperial unit support
- English and Korean interface
- Compact formula reference for common machining checks

Useful for everyday CNC work
- Check spindle speed from tool diameter and cutting speed
- Calculate feed rate from RPM, flute count, and feed per tooth
- Convert spindle RPM and diameter into surface speed
- Back-calculate RPM from target cutting speed
- Check chamfer width or axial length from angle and known dimensions

CNC Quick Calculator is built for fast input, clear unit labels, and repeat calculations without unnecessary complexity. If you need a cnc calculator, machinist calculator, speeds and feeds calculator, or rpm calculator for practical setup work, this app keeps the workflow simple.

Install CNC Quick Calculator for faster CNC setup calculations on the shop floor.
