10.1 Principle and Overview
You can program an entire family of parts in a single part program.
You do this by entering variables called
Q parameters instead of
fixed numerical values.
Q parameters can represent information such as:
■
Coordinate values
■
Feed rates
■
RPM
■
Cycle data
Q parameters also enable you to program contours that are defined
through mathematical functions. You can also use Q parameters to
make the execution of machining steps depend on logical
conditions. In conjunction with FK programming you can also
combine contours that do not have NC-compatible dimensions with
Q parameters.
Q parameters are designated by the letter Q and a number between
0 and 299. They are grouped according to three ranges:
Meaning
Range
Freely applicable parameters, global
Q0 to Q99
for all programs in the TNC memory.
Parameters for special TNC functions
Q100 to Q199
Parameters that are primarily used for cycles,
Q200 to Q399
globally effective for all
programs that are stored in the TNC memory
Programming notes
You can mix Q parameters and fixed numerical values within a
program.
Q parameters can be assigned numerical values between
–99 999.9999 and +99 999.9999. Internally, the TNC can calculate
up to a width of 57 bits before and 7 bits after the decimal point
(32-bit data width corresponds to a decimal value of 4 294 967 296).
