Origin/consistency of chipload recommendations

[WillAdams (William Adams (Carbide 3D))]

I was hoping Jupyter Notebook could be used for this sort of thing:

Jupyter Notebook as a CNC machinist notebook

I’ve been trying to find something well-suited as a CNC machining notebook — Jupyter Notebook seems a good choice, so here are some thoughts, notes, and sample code. Google has a server up: https://colab.research.google.com/notebooks/welcome.ipynb Here’s a bit of code which will allow one to calibrate the machine for belt stretch per: http://docs.carbide3d.com/shapeoko-faq/how-to-calibrate-the-machine-for-belt-stretch/ #@title Calibration for belt stretch Units = 'Millimeters' #@param ["Inch…

and was working through that at:

Tutorial on feeds and speeds

I’m afraid that this will be a bit of a cheat — I’m going to try to crowdsource an understanding of this. Let’s start by looking at all the variables: Material being cut — this should be groupable into a couple of categories, ideally matched up with typical endmill manufacturer recommendations: Hardwood Soft plywood MDF/Particle board Plastic (hard) Plastic (soft) Acrylic Metal (ferrous/non-ferrous), specific alloys and elements (are there any elements in their native form which are usefully …

which at least resulted in the nice interactive Tableau version:

Perhaps we should just make a version of that which has only the selection options:

• chipload
• feed
• speed
• endmill diameter
• number of flutes
