Mathematical model of the hole drilling process and typical automated process for designing hole drilling operations

摘要

In the paper, we discuss the mathematical modelling and optimal control of hole drilling. The drilling feed is considered to be a control action, while the cutting force is a controlled variable. Transfer functions of the regulators were obtained, with the cutting force variance used as a quality criterion for the automatic control system. The paper also presents problems connected with the structure of a typical automated process for designing a hole drilling operation. A block diagram of a typical automated process for designing hole drilling operations was introduced. The processed algorithms for setting regulator parameters according to a priori technological information and program protection were also introduced, which allowed for automation of the process study of the automatic control system for hole drilling operations.
