But it is a bit limited in that it only covers two mill profiles (end and ball) and only covers metal (5ish types, SS, Iron, Aluminum, a couple others). Unfortunately, I mostly cnc wood and acrylic, and a tiny bit of aluminum. I also often use different mill profiles. So great but not so great for woodworkers. App developer quickly responded (2024) they plan to add wood profiles, which is hopeful. ### 5/5 — Must Have for Machinists *2024-02-08, version 1.3.0* This app is the greatest, best designed, user friendly, and helpful app for machinists. ### 5/5 — The only app I’ve ever reviewed *2022-11-03, version 1.3.0* Hands down the best feeds and speeds interface I’ve ever used. I do a lot of test cuts from a lot of different tooling companies so being able to browse through their catalogs with this app handy makes my workflow so much better! The interface is extremely easy to use and is a priceless tool in my day-to-day work. All of the other calculators ask you for meaningless information when calculating cutting data, this app simplifies it down and uses the base calculations that all of the tooling manufacturers and CAM systems use. It’s also a step above using a calculator manually to get this data. Would rate 10/5 stars if I could. A+++ ### 5/5 — My Daily Companion in the Shop *2022-04-26, version 1.3.0* I love this app! I use it daily for calculating chip thinning feed rates and love how fast simple and smooth it is to use! The UI is intuitive and easy to use. No complicated menus or too much clutter. It just does what I need it to and nothing more or less. It’s a great app and is packed with helpful data that I used to have to lookup or find recommendations for start values on. **Developer response:** Thank you so much for this review! I really appreciate your comments on how fast and intuitive the user interface is and it’s wonderful to hear that you are using the app daily to calculate your cutting data As a machinist myself my aim was to develop the app with minimum data entry and keep it as simple to use as possible while providing reliable cutting data so it’s great to get a review like this! I am looking to add some additional features and options in the next release while keeping the same overall feel and ease of use so if you have any suggestions for features you’d like to have it would be great to hear them Thanks again for the amazing review! Dave ### 5/5 — Best interface for speed/feed calculator! *2021-10-13, version 1.3.0* This app is the easiest to use for speed and feed calculations. The visual interface is excellent! When I’m trying to find the best parameters, being able to drag the tool up and down with constant recalculation is perfect. It lets me focus on my target without getting bogged down in data entry. ### 5/5 — Great little calculator *2020-12-04, version 1.3.0* This is a very simple and intuitive calculator, much simpler to use than most. However it needs more materials, various woods and plastics would be nice. ### 3/5 — A very good cnc calculator *2020-07-25, version 1.3.0* A very good CNC calculator but the chip load table lacking an entry for acrylic, a very common material for CNC shops doing signs and prototypes. ### 5/5 — Cutter on iPad *2019-10-03* Very good App looks good on iPad too. ### 2/5 — Good app *2019-06-20, version 1.1.1* It’s a cool app but I wish it had a standard option not just metric ## Frequently asked questions about Cutter ### What does the Cutter app do? The Cutter app is a calculator designed to determine optimal milling speeds and feeds for endmills and ball nose cutters. It helps users generate baseline cutting data based on tool parameters and material groups, supporting both metric and US units. ### What are the key features of the Cutter app? Key features include calculations for Material Removal Rate, effective diameter for ball nose tools, chip thinning, and ball nose step over/cusp height. Users can also slide tools to adjust cut width/depth, set maximum RPM, and share their cutting data via text or email. ### Is the Cutter app free to use? Yes, the Cutter app is available for free. It does not have in-app purchases or advertisements, making it a completely free utility for users. ### Who would benefit from using the Cutter app? This app is ideal for machinists, CNC operators, and anyone involved in milling operations. It's particularly useful for those who need to quickly and accurately calculate speeds and feeds for various cutting tools and materials. ### Can I use this app for different types of cutters? Yes, the app specifically calculates speeds and feeds for both endmills and ball nose cutters. It provides specialized calculations for ball nose tools, such as effective diameter and cusp height. ## Version history (last 5 releases) ### 1.3.0 — 2020-02-01 New in this version: - Radial chip thinning - Material removal rate - Axial chip thinning for Ball cutters We've fixed some bugs and made some improvements to the UI Please leave a review along with your suggestions to improve Cutter App. ### 1.2.0 — 2019-06-26 Now with Standard (U.S) units!
