Measuring brad point drill bit

Postby John SCC » Tue, Apr 16 2019, 3:06PM

Anyone have a way of automatically adding daylight to a brad point bit after measuring? We usually add to the daylight manually using the tool table, but when we forget to, our through holes are obviously not correct. I have tried editing the automatic tool measuring subprogram to check to see if we measured that particular tool and then adjust the daylight if so, which worked until we shut the machine down and rebooted the next morning. Apparently when we boot up the original Thermwood subprogram is regenerated? Any insight would definitely be appreciated.

Control Nesting provides the option shown in the attachment. It works well.

I do remember seeing that now that you mention it. The only reason we did not explore that was because that needed to be changed per tool group. That isn't a huge deal but we also would need to remember to add depth to any code generated outside of control nesting. This will work for us for now though, I'm still hoping for a solution that removes the possibility of forgetting to update a tool group or something along those lines. Thanks for the quick reply.

John,

You are correct in that THM rewrites the tool measurement program when the machine is rebooted. Instead, write a program that calls the tool measurement subprogram, then add in you extra code for adding daylight to the tool. Depending on your THM version, you can read the current daylight, log it, compare it after tool measurement is done, and if it is different then add daylight to it. That would be the safest way in the event the drill isn't measured you aren't just adding daylight to it every time tool measurement is ran. You can run that program then rather then the THM tool measurement program to measure your tools.
