Mike,
I have attached a pm4 file to show the thread mill option and the helix.
In G54 you will see I have programmed a 1."-12 thread using a thread mill
with a effective cut dia. of .79 with insert. SmartCam will calculate the
swing dia. or radius of the cutter path by simply inputting the minor dia.
and major dia's. When you use the helix command you must input the start
and end rad. In G55 I used .105 rad and a pitch 1/12
In the helix you must also program a lead in and out of the cut. Both
threads are 1.-12 Hope this helps.Dave Wolfgang CNC Programmer/Supervisor www.hrindustries.net ----- Original Message ----- From: "MikeH" <[EMAIL PROTECTED]> To: "'[EMAIL PROTECTED]'" <[EMAIL PROTECTED]> Sent: Wednesday, September 05, 2001 9:55 AM Subject: [mfg-smartcam] thread mill > > > Hello, > > I am trying to form a .9375 -16 thread. > I get the following code when using thread mill. > I believe the code at line N10 is wrong. > Shouldn't the I value be 1/2 of the major dia.,which is .9375? > Also,is it possible to use helical geometry instead of the thread mill > command to do this? > Is it also possible to create 2 passes using thread mill, or does the > software limit you to one single turn helix? > > N0 G00 G80 G17 G40 > N1 G92 X0.0 Y0.0 Z0.0 > N2 T13 > N3 S1200 M06 > N4 G00 G90 X-0.2815 Y-0.65 M03 > N5 G43 Z2.0 H13 > N6 M08 > N7 Z0.1 > N8 G01 Z-0.4375 F40.0 > N9 G42 D13 X-0.2002 F5.0 > N10 G02 X-0.2002 Y-0.65 Z-0.5 I-0.4688 J0.0 > N11 G40 G01 X-0.2815 > N12 G00 Z1.0 > N13 G80 M09 > N14 G00 Z0.
