As shown below, I took a stab at entering the info for your spindle into a spreadsheet to see how you’d likely cut Baltic Birch. It should take about 7 lbf of cutting force and 0.331 HP cutting power. Assuming the values I entered in cells G5 - G8 for your spindle are correct, the spindle current increase when cutting should be about 0.8 Amps. If you enter the VFD’s displayed spindle current values when the spindle isn’t cutting and when it is cutting into Cells D32 and F32 respectively, the spreadsheet will calculate the actual cutting parameters (Cells H32, and D31 - J31). As shown in the second picture that’s how I estimated the K Factor for Baltic Birch. You can easily make copies of your spreadsheets to share and/or for your own future reference. A drop down menu accessed via right clicking the spreadsheet’s tab at the bottom of the workbook gives you several options for that.
The latest workbook (with additional spreadsheets) is available here.
