Milling Speeds and Feeds Pro is built for machinists, CNC operators, and shop teams who need dependable cutting numbers quickly. It gives practical starting points for RPM, feed rate, and surface speed, then lets you save, reload, and refine setups for real work at the machine.

Whether you are dialing in a one-off part, repeating a proven setup, or training newer operators, this app helps reduce guesswork and keeps your process consistent across jobs.

Why shops use it
– Fast speeds and feeds calculator for daily milling setup
– RPM calculator based on SFM and tool diameter
– Feed rate calculation using proper tool model logic
– Surface speed (SFM) output for quick verification
– Built-in support for both end mills and drills
– End mill feed uses chip load and flute count
– Drill feed uses IPR (inches per revolution)
– Material-aware defaults to speed up first-pass programming
– Saves reusable jobs for repeat work and family-of-parts workflows
– Reloads saved jobs directly into inputs for recalculation and edits
– Clear action feedback with toast confirmations
– One-tap share for setup communication between operators and programmers

Material profiles included
– Aluminum
– Mild Steel
– Stainless Steel
– Brass
– Titanium

Practical controls for real setup work
– SFM mode selector: Low, Standard, Aggressive
– Flute count input for end mills (with explicit default)
– Diameter formatting for clean, professional input values
– Randomize option for realistic in-range sample setups
– Refresh and New actions to reset quickly between jobs

Built for speed on the shop floor
– Clean SwiftUI interface with quick navigation
– Designed for fast entry with minimal taps
– Useful for CNC mills, manual milling workflows, and prototype work
– Ideal for setup sheets, first-article runs, and process handoff
