ports of the programmable logic controller (PLC); 2) in the text of the part program (in the
CNC system), at the desired operation, these M-functions are called before the operation where
adaptation is required. In this case, the control of the cutting parameters is transferred to the
USO, which generates the control signal. The control signal can be represented both in analog
form, with the amplitude proportional, for example, to the feed value, and in digital form. It
depends on the characteristics of the PLC and on whether it has free inputs.
