I've downloaded the videos. What speeds and feeds are you using for each drill. Give us some details of the setup. What type of drills and also the steel grade of the drilled plate etc.

Your camera saved videos in uncompressed avi format last time when I used it. These videos are mpg. Did you convert the files to mpg or changed settings on the camera. Virtualdub can't handle mpg files.

I converted the Videos using Hamster free video converter... The Feed for drill was 44mm/min to 22mm/min and Spindle speed 500RPM to 200RPM considering smaller to Larger drill. The plate material ASTM A 283 C - A 570  and we used HSS drills.
The second plate drilling in progress.

Nice job. How do you compare the cycle time with your previous setup, including the time spent in marking the plate manually and punching centers on it. You can save time by overriding the rapid speed to the max. You'll have to make changes to config/general config menu and deselect "Lock Rapid FRO to Feed FRO". That way your rapid feed will remain at max. while you change the Machining FRO.

Converting videos to mpg doesn't compress them as much as you can with xvid. Did you try the virtualdub tutorial I sent to you. Still waiting for the coolant drain systm videos.

Zafar... As you knew very well CNC saves time.. Who knows better than me, all my woodcarving design i have done by CNC i can't make 10% of them by hand in my whole life...
Centre marking may take atleast 2 Hours for these 24 holes by manually... I think we saved 24 Hours in CNC drilling for single flange...

Wow..thanks i shall do it right now.. This thread will be my guidance for any help in future for such embedded tricks..

You are really master in tutorial writing.. I shall soon convert the videos with virtualdub  and shall sent you..
Thank You Zafar Sahab for the generous help:)

I know 24 hours mean a lot for a plant turnaround. I wonder if this saved time will result in you getting some extra time to spend at home or more work load piled up at your shop to speed things up ;-)

What's the total cycle time for these 24 holes in the flange. I believe these are the same flanges we used as test loads on the machine. These were 315 kg each.

Nope...These flanges are 1meter diameter and 90mm thick...We changed the strategy for the second flange.. Instead the Deep Drill cycle we used Break Chip drill cycle.. And all the holes finalized within 04 Hours...This time also perform the chamfering...

Some Pictures. We have two drums full of these chips/material shavings...

Next retrofit upgrade ... A chip conveyor perhaps?
