X7 Tool Manager / Center drill issue

[Bridgeportboy]

When I attempt to describe a standard 60 degree shoulder Center Drill I get the following error.

Am I doing something wrong or is this a bug?

 

 

Thanks,

Try setting it as 120

[Bridgeportboy]

I tried it and 120 goes the wrong way, Flattens out the shoulder angle instead of making it steeper.

Iv'e used center drills for 30 years and have yet to use one with a 90 degree shoulder.

Are you trying to get a 60 included angle?

 

180 would be flat, 120 would be a 60 included angle, 150 will be 120 included angle, it comes from the horizontal place not the axis of the tool

[Bridgeportboy]

Yes, 60 degree included angle. Try it in the tool manager and you can watch the angle change, 120 is not the 60 that I need.

Bridgeportboy - What that's telling you is that the cutting length can't be calculated with that 60* angle... Try making your cutting length >13mm and it'll work. It's being constrained by the drill diameter & length and working backwards.

 

I'll suggest they try to make the error more descriptive.

I could be wrong, but I think the main point of the OP was that the tool manager its setup to make a 90 degree center drill, however since every standard center drill I have seen is 60 degrees included.. you would imagine you could change it to 60 degrees, if you do it gives the error shown.

 

Also .. if you look at standard definitions of lengths for center drills the drill length is always defining the length of the pilot drill part of the center drill .. not overall length of flute..

 

So therefore using standard nomenclature (and dimensions / angles) for center drills that has been that way for many years the tool manager doesn't seem to function correctly..

 

(oh and it would be 180 - 120 to get a 60 degree included so the number should be 60.. just as the 118 indicates an 118 degree tip)

 

In case anyone wants to argue the 120 vs 60 included bit.. I include the following from a tool manufacturers catalog..

 

Combined drill and countersinks(center drill bits) are designed with 118° Point Angle and a 60° Countersink Included Angle with Spiral Flutes. Combined drill and countersinks(center drill bits) are used for center holes in work pieces for additional manufacturing operations. Available in HSS, COBALT, and CARBIDE. The Bell type is furnished with a 118° Point Angle and a 60° /120° Included angle. Combined drill and countersinks(center drill bits) also available in an extra long series.

The math is a LOT easier on a 90.

 

Just sayin'........

Aaron, Did you actually try this or is this a guess that it'll work because it does'nt work on my box?

I get the same error message that is pictured in my 1st post.

MCX7 acts differently on most P.c.'s

 

Did you trying rebooting?

[djstedman]

Bridgeportboy - just tested what Aaron said and it does work, at least on my machine it does.. its Cutting Length (top field) that needs to be changed though .. not the drill length field right above the angle..

[Bridgeportboy]

Got it! Thanks to all for the help.

Steve - Glad you got it sorted out Sorry I wasn't around to clarify further..
