Your post is dated 2003. If it is still available I would like a copy of your cheat sheet on canned cycles, particularly G76.
Thank you,

DESCRIPTION OF MAIN PROGRAM :-
G76 FANUC THREADING CYCLE CNC PROGRAM WITH DESCRIPTION - CNC PROGRAMMING TUTORIAL

N10- Tool change command , select tool no. 1
N20- Spindle ON anti clockwise , constant spindle speed command , speed is 1000 rpm
N30- Rapid action command where X45 and Z5 .
N40- Threading cycle command , P020060
( P02 = No. of finished path
00 = Chamfer amount at end
60 = Angle of tool tip ) ,
Q100 = Each cut is 0.1 mm ,
R20 = finishing allowance 0.02mm
N50- Threading cycle command , Minor dia X axis , threading along Z- axis up to -50 , Threading depth , Depth of finish cut 0.1 mm , pitch is 2 .

: M40X2

Major diameter is 40
Pitch is 2
Thread depth calculation = Pitch x 0.61363
= 2 x 0.61363
= 1.227 mm in micron is 1227

Minor diameter = 40-1.23 = 38.7 mm

N60- Rapid action command where X45 and Z5 .
N70- Spindle off , coolant off , main program end .

DESCRIPTION OF PROGRAM :-

Starting calculation please click here
01421- Name of program
N10- Tool change command , select tool no. 3
N30- Coolant ON
N20- Spindle ON anti-clockwise ( for RH thread) , constant speed command , speed is 1000 rpm
N40- Rapid action command , where X50 and Z2
N50- Threading cycle command , P01 - no of finish path
00 - chamfer amount is 00mm
60- angle of tool tip ,
Q100- each cut is 0.1 mm ,
R20- finishing allowance 0.02 mm
N60- Threading cycle command , X45 is end diameter , tool threading upto -55 in Z axis , P thread depth 1.227mm , depth of finish cut is 0.2 mm , R taper thread parameter is 10.5 , F is pitch is 2.

P Depth of thread = pitch x 0.6136 = 2 X 0.6136 = 1.227 mm = 1227 in micron
R taper thread parameter = ( end dia. - start dia ) / 2 = (45-24) / 2 = 10.5

N70- Rapid action command , where X50 and Z2
N80- Spindle OFF , coolant OFF , main prog. end .
