The formula I gave you will give you chip load per tooth for whatever number of flutes the user enters. The sole purpose being, more advanced users could say " I want this particular chip load" and adjust their settings from the recommended as needed. For Example, I select a .25 Inch, 3 flute mill. I'm running my machine at 24,000 RPM in aluminum on aggressive. The Calculator tells me my Speeds and feeds are 2438mm/m. 2438/(24,000x3)=.033 of chip load per tooth (CLPT). Which is .0012in That's a finishing pass load there, so I would want a higher chip load. So there's a thought. Instead of calculating it automatically, would it be possible to just add the calculator to a tab? so basically I imagine it looking like: _______Feed Rate / (________Spindle Speed x _________# of flutes) = _____________CLPT So instead of using the predefined chiploads we have hardcoded (which is how we are getting the feedrates based on the inputs you are allowed in the app) you want to be able to change ANY of the numbers to get your own individual output based on what you decide you want to provide the calculator? |

I see what you are getting at, but I don't want to go there. There is a fixe chipload table table in the background that is referenced. When Jody's program calculates things, CLPT is being pulled from the table for that material and cutter diameter and the feed rate is being generated from that and the user's RPM and flute count inputs. I gave Jody the chipload chart with intentional de-ratings from what you see in a lot of chipload charts. For instance, some charts recommend a .006 chipload for aluminum with a quarter inch end mill. You'll never realistically obtain that on existing MillRight or competitors machine. For instance, at the bottom RPM of 16k on the DWP611 with a 2 flute you need to feed 192 inches per minute (4876mm/min) to obtain a .006" chip load. Or, with a single flute you'd need to feed 2438mm/min. You'd have to cut REALLY shallow for the machines to handle that chip load in aluminum to the point that small variations in bed height would lead to excessive cutting forces on the machine. Now, I know that's not exactly what you are getting at. I'm just addressing the de-rating. As to the calculator by itself: I'm opposed to making even a tab for manual calculation. I think it's useful to more advanced users, but I really would rather this just be a place for people to come get a baseline to work from. Two features that achieve similar things can be a little overwhelming to the new guy or gal that is already inundated with learning new CNC concepts. I'm open to debate on it, that's just the way I view it now. Derek EDIT: I would be okay displaying the chip load pulled from the program's table. You're no fun. Lol But I see where you're coming from. |

Happy to have done it. Hoping everyone is finding it useful. I hope to continue to add features and improve it’s usefulness. If anyone has any suggestions of things you would like to see improved or added, please let Derek or I know.

Check out the calculator here. It allows you to specify your machine, material, end mill characteristics, and RPM to get recommendations for your depth of cut and feed rate. It also has some other handy features like a inches to mm calculator and the "fine tuning steps/mm" calculator like is found on the spreadsheet in the Assembly Tips forum. Some additional features may be added later. Credit goes to Jody Reimers (jreimers here on the forum) for this great piece of work. He has made an excellent contribution to the community with this application. It is also launching as Android and iPhone applications. As of 10/22, the iPhone app is available and the Android app is pending We appreciate your feedback. Thanks again to jreimers for the great work. What is the fastest that the Carve King can go - or it's feed speed limit? I've never run it over 90 - but the calculator is giving some figures of over 100 . . . just don't want to set it too high for the machine. |

Everything it outputs are within the range of the machine. Max is 137 IPM. Good question.

Just wanted to announce that version 2.0.0 for Android dropped today. iOS is still in review. Apple usually takes about 24 hours to release.
You should notice quite a few changes. We have added a GCode reference guide and added access to all of your video tutorials in the app. As well as some interface improvements.
As always your feedback and suggestions are requested and appreciated.

I just updated the iOS app on my phone. It looks great Jody! I like the scallop calculator as well.

I see some YouTube video issues I hope to fix tomorrow.

Be on the lookout for an upgrade coming sometime today. Version 2.0.1 is finished and off to the app stores. Waiting on them now. It includes the fix for the video scaling issue. A couple of minor bugs fixes and most importantly of all... it's faster!

Just updated on my Android phone. Looks great, and it definitely seems quite a bit speedier. Thanks!

I love the desktop and Android app great job. The only gripe I have is I am a good old Canadian boy and I work in millimetres. Would be great to have that option (although I can do all the conversions manually based on what is there on inches. Although a 6mm endmill is not the same as a 1/4 inch endmill etc.
Cheers!

There's a conversion calculator in the app and if you click the settings icon (little gear) you can change the default units. |

I think he is asking that I include some metric end mills along with the imperial ones. |
