Cut distance
« on: May 13, 2014, 09:06:03 AM »
Hi, i want to know if i can somehow compute or find the cutting distance of a program using Mach3 or if you know some program or script that does this. I need this feature to know when to change the milling bit.

Thanks,
Dan

Maybe this will help ?

Program run time divided by an average feed rate would give a ball park  cutting distance. Just a thought.
In industrial setting they check the tool for wear, and I have nothing to post on how that is done.

FWIW,

I reset all fields then ran the Roadrunner file.

Reopen and check the data.

You have to consider the "air" time as these are total axis moves, but it will give you a pretty good idea.

Maybe not the best way to monitor tool wear, but can see it being used in conjunction with other methods.

Thank you for all the reply.
Maybe i can apply some compensation like 10-15% for air moves.

Or maybe there is somewhere where i can find all the rapid moves (high speed moves) and low speed moves ? because like that i can approximate better the cutting distance. High speed moves are all executed in air. Low speed moves are all executed while cutting, excepting  plunging which is made in the last 2 mm above the machined part in  air but at low speed.
