I am trying to cut into a 1/8 inch plywood using Amana 46280-K
These are the the values I got from tool’s website -
Diameter - 1/32 inch
IPM - 40" - 108"
Chip Load/tooth - 0.00075" - 0.002"
RPM - 18000
This is the calculations I have made
Feed = RPM * Flutes * chip load (18000x4x0.00075 = 54)
Rest values I went with defaults of Carbide create. With this the tool was plunging too much into wood and was always workpiece getting thrown out. So I decreased the Feed to 30. Still I have same behavior. Attaching my Carbide Create File and the screenshot of tool parameters. Can the experts comment what I am doing wrong.
Try reducing the Depth (Depth of Cut) from 0.05 to 0.01. You can look at Carbide 3D’s default settings for their 1/32 endmill, at least on mine it is 0.01.
I had a look at your file and wonder what workholding method you are using ?
You have your total depth of cut set to 1/8", which is also your stock thickness, and given the vector you are using, there are lots of small individual parts that will be cut completely free from the stock when the toolpath reaches max depth. I highlighted a few ones to illustrate my point:
So regardless of the feeds and speeds used, it seems normal to me that these parts would fly out near the end of the cut, if you are using a typical workholding like clamps.
Was it your intent to cutout all those pieces down to full stock depth ?
