CNC Milling Speeds & Feeds Pro

You bring sharp instincts to every run. Milling Calcs levels up feeds, speeds, RPM, chip load, records, and setup sheets for cleaner shop wins on every shift in the shop.

You are the kind of person who checks the cut before committing the part, and Milling Calcs is built for that level of care. Whether you are running a CNC mill, planning a manual setup, dialing in feeds and speeds, or saving shop records for the next job, this app helps you move faster without treating the numbers casually.

Milling Calcs gives machinists, CNC programmers, setup techs, fabricators, students, and garage builders a practical collection of milling calculators, shop references, saved records, and setup tools in one focused workspace.

• Calculate spindle RPM from cutter diameter and surface speed.
• Estimate feed rate from RPM, flute count, and chip load.
• Find chip load per tooth from feed rate, RPM, and flute count.
• Convert feed per revolution for drilling, boring, and production planning.
• Work with surface speed, SFM, IPM, tool diameter, cutter geometry, and common shop units.
• Plan a milling or drilling job from material, tool size, machine assumptions, SFM, and feed data.
• Use a cut optimizer for material removal rate, estimated cutting force, and tool deflection.
• Check material removal rate from width of cut, depth of cut, and feed rate.
• Use true position, arc, chord, segment, sine bar, shrinkage, tap drill, and layout calculators.
• Keep reference data close, including drill sizes, tap drill charts, thread data, pipe threads, G-code, fractions, and metric conversions.

Milling Calcs is not a toy calculator with one answer screen. It is a shop notebook for the work around the answer.

• Save calculation records for later review.
• Keep notes with the setup that created the result.
• Mark important records as favorites.
• Browse records by date in the calendar workspace.
• Search records, notes, tools, materials, machines, setup jobs, and local reference data.
• Build setup sheets from saved calculations.
• Add customer, DOC, and WOC fields to a saved calculation record.
• Share setup information as plain text, PDF, JSON, or QR setup cards where supported.
• Use import and export tools to move shop data between devices or keep a backup.

The app is designed for real shop use:

• Large, readable inputs.
• Clear units beside the numbers.
• Fast reset and randomize tools for calculator testing and learning.
• Report a bug access from calculator menus.
• Organized tabs for Calculate, Records, Libraries, Reference, and More.
• A More workspace with Today, Calendar, Data Transfer, Settings, About, and Sources.
• A record view that keeps inputs, outputs, notes, tags, dates, and setup sheet actions together.

Free users can get real value from the core calculators and saved records. Pro adds room to grow with unlimited records, full libraries, advanced setup exports, reports, and more complete planning tools.

Use Milling Calcs when you need a quick RPM check before a cut, a feed rate for a drill, a saved setup for tomorrow, a shop reference during layout, or a setup sheet that explains how the job was planned.
