The subroutine techniques shown in the previous example are almost identical to the
techniques that the conversational APT system uses. So, even if you are going to be
inputting conversational programs, and seldom writing manual programs, this will give
you an insight into how the conversational side will generate CNC programs for you.
Notes about the punch program:
1) The conditions and offsets were for 1/2"thick steel using 010" wire. You MUST check
in your condition manual to obtain the correct conditions and offsets for your application.
2) Note that the main program (through the M02) will be very similar from one program
to the next. Only the subroutines will change dramatically from one punch program to the
next.
3) Parentheses are allowed in the program at any time to allow you to include a message
to the operator.
Example: N0055 MOO (SUPPORT THE PART AND PRESS RST)
4) A CRT command is available to echo a note onto the CRT while the machine is
running.
Example: N0009 CRT (ROUGH CUT JOB #1)
NOTE: maximum of 24 characters inside( )

Figure 9-3 shows a die opening. In this example, we make two total passes, one rough for
the tapered area and one skim for the land (tapered area first). Note that this is the die
opening for the previous punch example. While two passes are being made, we make
them in the same direction. We are also pulling a fast one and tricking the control with
the optional block skip technique for the tab area during the roughing pass. See if you can
figure out what is happening.
NOTE: We are using a 1 cut on size offset for the taper cut, since no trims will be done
on the tapered area.
