Recommened Tool Setting for uxcell 1 inch bit

I recently got a uxcell 1/4 inch 1 inch bit from here

I wanted to ask what parameters I should use to add it to library. I have

RPM - 18K
Feedrate - 10 mm/min
Diameter - 25.4 mm

I am not sure what to set for Plungerate and Depth. I am very new to CNC and any help will be great.

The router speed setting should match the feeds and speeds for your selection of endmill and material. Please see:

(there’s a row matching dial settings to RPMs at the bottom)

There’s an interactive version at: https://public.tableau.com/profile/willadams#!/vizhome/Carbide3DCNCFeedsandSpeeds/Sheet1?publish=yes

Note that the feeds and speeds calculations in Carbide Create were updated for trim routers in 433 and 440 and later use a curated set of feeds and speeds which are stored in CSV files.

See https://www.youtube.com/watch?v=S9bceJxpqG0 for concepts on this and see the series #MaterialMonday: #MaterialMonday on YouTube for specifics.

You should test feeds and speeds in a piece of scrap using the technique at: https://precisebits.com/tutorials/calibrating_feeds_n_speeds.htm

Another consideration is Climb vs. Conventional Milling and tooling engagement — where possible avoid slotting and add geometry and cut as a pocket (Adding geometry to cut as a pocket with a finishing pass ).

Extensive discussion at: Origin/consistency of chipload recommendations and https://shapeokoenthusiasts.gitbook.io/shapeoko-cnc-a-to-z/feeds-and-speeds-basics with a spreadsheet for this at: Speeds, Feeds, Power, and Force (SFPF) Calculator

Hi @cspnanda,

(Adding this to @WillAdams’s excellent pointers)

Note that the parameters depend on the material you will be cutting (notice that in Carbide Create tool library, the recommended feeds and speeds are organized by material).

That link you referenced mentions a recommended feedrate of 8 to 12 meter per minute, so if you want to follow that guideline, you should enter 1000mm/min, not 10. It sounds like a reasonable value to me for surfacing wood. It could probably be pushed to 1500mm/min.

Plunge rate does not matter much as you will be doing very shallow cuts with this tool, so say 500mm/min.

For depth per pass, I would use 0.5mm / 0.02" for a start.
