4.1 Creating Part Programs
Layout of a program
A part program consists of individual program
blocks. The TNC numbers the blocks in ascending
sequence. Program blocks contain units of informa-
tion called
words.
Plain language dialog
You initiate a dialog for conversational programming by pressing a function
key (see inside front cover). The TNC then asks you for all the information
necessary to program the desired function. After you have answered all
the questions, the TNC automatically ends the dialog.
If only a few of the words in a block need be programmed, you can cut off
the dialog and end the block before the dialog is finished.
Function Key
• Continue the dialog
• Ignore the dialog question
• End the dialog immediately
• Abort the dialog and erase the block
