Short Program

[Geof]

How short can a program be and still qualify as a program?

I had drilled and parted off some short pieces of leaded hexagon which needed tapping 1/2"-20. I didn't want to disturb another setup on the lathe so I figured on tapping them in the mill. Five lines written in MDI and a cycle time of 2 seconds made them the shortest job I have ever done.

ok,i'll bite and say 3 lines of code

G00 G90 G54 X0 Y0 S (your choice) M03
G43 Z1. H03
G84 X0 Y0 Z-.5 R0.2 F (fitting to speed)

But you did not stop the programe with M30 nor did you lift things clear to reload.

Add: G53 G00 Z0. M30

ok ,I'll give you the m30.
But I didn't take into acount the ( some short pieces ) more then one.

You remind me of the people I used to get on the telephone, when I took customer service calls, I often wanted to scream "reading the fffffffing instructions!!!!!!!".

But I never did, at least until after I had hung up the phone.

theres allways one of us out there,that's how you learn to hone those skills!

Technically a program must contain at least a program number and an m30 on a Haas control. Yes, I know it will do nothing - but will execute. I suppose you could add a g4 to just kill some time.

Okay just to be 'technically correct' (after all I am most often the nit picker ) I will add a program number and save it to memory. Just to keep all the technical people happy.

Quick Drilling PGM
1) PGM#
2) S-PGM G-Models
3) Tool Call, Spdl Speed, First Location
4) Height Call G43
5) Drill Cycle
6) S-PGM Incremental Locations
7) S-PGM Tool Retract G-Cancels Y Home
8) M30

Quick Facing PGM
1) PGM#
2) S-PGM G-Models
3) Tool Call Spdle Speed, Start Location
4) Height Call G43
5) Feed Across
6) S-PGM Tool Retract Send Y Home
7) M30

I would safely say 7 Sequence Blocks is the shortest without using MDI.
