Calculating the tool diameter of v-Bits

[Daniel yOPERO Garrido]

I am sure most of you have already worked it out but I thought it may be of interest to new people when trying to provide the gerber to gcode converter with the "Tool Diameter" that in the case of V-bits is going to be function of the depth to be routed.

And here a table with some common angles:

zD	15	20	30	45	60	°
0.02	0.005	0.007	0.011	0.017	0.023
0.03	0.008	0.011	0.016	0.025	0.035
0.04	0.011	0.014	0.021	0.033	0.046
0.05	0.013	0.018	0.027	0.041	0.058
0.1	0.026	0.035	0.054	0.083	0.115
0.15	0.039	0.053	0.080	0.124	0.173
0.2	0.053	0.071	0.107	0.166	0.231
0.25	0.066	0.088	0.134	0.207	0.289
0.3	0.079	0.106	0.161	0.249	0.346
0.35	0.092	0.123	0.188	0.290	0.404
0.4	0.105	0.141	0.214	0.331	0.462
0.45	0.118	0.159	0.241	0.373	0.520
0.5	0.132	0.176	0.268	0.414	0.577

PD:sorry to send it again but my previous post got deleted, somehow....

Thank you! I haven't done the math :P

Are you sure those V bits are 60⁰? They look 30⁰

Well spotted!!!  It is certainly a 30 ⁰ v bit bought from china and it has a suggested Cutting edge diameter of  0.1mm.

I have edited the original post because it had the wrong value on the tan() function.

Please review!
