Multiple Machine Control and Programs

Different computers may be used depending on the application. They
may be mounted in the balancing machine’s instrumentation console, or
in a central electronic data processing room. A computer may control one
balancing machine, or a series of machines.
Basic computer programs are available for single and two plane bal-
ancing, field balancing, and flexible rotor balancing. Software libraries
for optional subroutines are continually growing.
Of course, the user may modify the available programs to his particu-
lar requirements, write his own programs, or have them written for him.
Thus, the potential applications of the computerized hard-bearing balanc-
ing machines are unlimited.
