Really short drill cycles

[Scott_M]

Here is a short video of a job I run a few times a months , usually 2-300 parts with 2 different sized holes. The drill cycles are so short it would be foolish to change the drill. So I change the part, drill them all , change the drill bushing and the drill and run them all again. The fixture locates the part very well and is adjustable for fine tuning. Repeatability is around .0005". I have air blowing through the fixture to clear chips and eject the part. It works pretty slick.
The parts are front sights for S&W revolvers.

I start spindle manualy and have no spindle commands in the code. The code ends with

M1 ( optional stop )
M47 ( repeat program from first line )

I also have an old PS2 mouse with the ball removed that sits on the table as a remote cycle start button.

All in all it works really well. Thought you guys might like to see yet another way to "skin a cat".

The cat doesn't stand a chance! Thanks for the video, Scott. Do you do all the machining for the sights on the Tormach?

And thanks for the M47, too. I knew about M1 but not M47. That will come in useful on my lathe as I make more model train wheels.

Is your PS/2 mouse in addition to another mouse you use for the Mach, er, PCNC interface? If so, how do you keep the buttons straight in Mach? That old a mouse doesn't have programmable buttons, does it?

Scott -

Very nice. I really love the fixture with the air-powered ejection. The mouse button seems to be the ticket, too! You might save a second by putting the mouse on the floor and tapping it with your foot as you tighten the clamp.

For some real fun, you could just have the program repeat and delay just long enough to set the new part, so you don't need to press the button for each part... but don't get distracted.

Thanks guys

The old mouse is an additional mouse. When I am done with the job I just coil it up and stick in the cabinet until the next run of the sights. My optical mouse sits next to the keyboard with the cursor hovering over the cycle start button on the Mach screen.
The sight blanks are wire EDM'd at a local shop. I drill them, mark them, blast and blue them.

The floor switch won't work. ( I usually run this job sitting on a barstool ) And I get way to distracted on a regular basis to use a delay But I like the way your thinking !
