Non cylindrical grinding by binary command is executed with both grinding heads.
The motion of rotary axis for workpiece is commanded with the binary data in path 1.
In path 2, the same binary data of C,A axes that is commanded in path 1 must be commanded
also in path 2 as dummy data.
The function “Retract in Binary operation” refers to the coordinates of the dummy C,A axes.
The binary command operation must be synchronized with the motion of C,A axes that is
commanded in path 1, so the synchronization between both head is realized by “Waiting function
between 2 paths”.
The motion of rotary axis for workpiece is commanded with the binary data in path 1,
therefore the operation of path 1 should not be terminated until the operation of path 2 is
terminated.
After removing head 1 by “Removing signal(explained later, chap. 4)” the operation of path 1
must wait until the operation of path 2 terminates.
The “Retract function in binary operation” functions each head individually
In path 2, the same binary data as path 1 must be commanded, because the C,A axes of path 2
is referred as the nominal axis for head 2.
The system parameter in path 2 for “Retract function in binary operation” must be set
based on the C,A axes coordinates in path 2.
