OPERATION
54
The format of machining programs created using the conversational
automatic programming function is different from that of NC–format
machining programs.
An NC–format machining program consists of NC block instructions in
which G codes, axis–address data, and miscellaneous functions are
combined. An NC block instruction corresponds to an NC operation.
A conversational machining program consists of processes. A process
here refers to a set of machining operations using one tool. The process
contains process data, such as a tool to be used and cutting conditions, and
figure data including the figure of a machined product. NC data necessary
for machining is automatically generated from the process and figure
data.
NC–format machining programs and conversational machining
programs are stored separately as shown below.

programs
A program is stored by each process block
(it corresponds to a tape length of about
0.76 m, 30 inches).
A program is stored by each character (it
corresponds to a tape length of about 2.54
mm, 0.1 inches).
Part program
storage
The storage capacity assigned to machining programs is determined
according to the length of the optional tape attached. Setting parameter
No. 9770 (NMEM0 to NMEM4) sets the ratio of the storage capacity used
for NC–format and conversational machining programs.
