Endmill Economics
INSTRUCTIONS:
- Enter machine information including torque/power curve.
- Get the current data on their existing endmill; speed, feed rate, width and depth of cut. Enter this information under the current conditions tab in the DC software.
- Record the cut using Harmonizer to verify there is no chatter. If there is chatter, select that in the current conditions.
- Load your endmill in the same, similar or another toolholder at approximately the same stick-out. NOTE: Tests show that the toolholder can have a major impact on the performance of your endmill. If you are not getting desired results, it would be wise to try a different toolholder.
- Load new assembly in spindle and tap the tool.
- Submit the DC/TXF file to BlueSwarf for Dashboard analysis and production.
- Use the Dashboard to find maximum available stable cutting parameters.
- Go to Analytics Tab, enter the before and after cost per cubic inch removed (cost per in3/m) in the above calculator.
- Adjust tool price to their endmill or inserts' cost and tool life on both tools to the same values. Enter shop's hourly rate for that machine. If you do not know, leave at default.
- If needed, run verification test at Dashboard settings using Harmonizer in case any non-cutter sourced chatter is encountered. Adjust speed accordingly. Use a new endmill for this.
- Measure tool life (it will likely be much better than their current). Enter that value in the analytics tab on the Dashboard side, leaving the user value at its current. Recalculate the ROI.
