Impact on Dashboard of Incomplete Data

We published THIS ARTICLE to illustrate what would occur if you try to generate Dashboards with missing key information. On this page we are using actual, fully interactive Dashboards to show the lesser impact of other missing or incorrect data. In these instances, the Dashboards are still functional and usable. 

Helix Angle

The Dashboard on the left is an endmill with a 40 degree helix. The Dashboard on the right is made from the same tap-test measurement with the helix angle set to zero. Note that the stability ranges for speed, width and depth of cut are unchanged. What is affected is the Accuracy (SLE) and Surface Finish (CDD) outputs.


The two Dashboards below are identical tap-test measurements but the helix angle setting is at 30 on the left and 40 on right. As above, the Dashboards are the same except for a minor impact on the SLE and CDD outputs. If you have to estimate the helix angle, it will still be functional.


Lead Angle

The lead angle on an indexable milling tool is for documentation purposes only and does not impact the Dashboard results. The Dashboard on the left is for a 45 degree lead cutter. The Dashboard on the right was made from the same tap-test measurement, but the lead angle set at zero. The results are identical.  


Variable Tooth Spacing

Picture
The Dashboard on the left is for a proportionally (equally) spaced endmill. For the Dashboard on the right, Variable Pitch is checked in the tool's setup file. The largest impact in the process damped region, the stable speed range from zero RPM. The proportionally spaced Dashboard will cut the width and depth of cut at 1700 RPM. With increased process damping, the variable spaced Dashboard can cut the same width and depth at 2100 RPM. This illustrates the importance of checking the appropriate characteristics of the milling tool.



Material

These four Dashboards are made from the same tap-test measurement The only difference is the material selected; P0, P1, P2, or P3. As you can see locations of the stable speeds do not change. The maximum stable depth of cut does, decreasing as the material becomes harder.
