The issues of developing control programs for machine tools with dynamically changing kinematics are considered. The features and additional control commands related to changing the kinematic scheme, controlling the channels of the control system, switching the operating modes of the axes, saving the state of the M and G-vectors are generalized. The features of the execution of the control program in one or several channels are considered. In the case of a program running in several channels and using processors with low performance, it is possible to use a memory-oriented architecture of the control system. A technique for developing control programs has been developed, individual steps of the technique have been identified, features and ways of their implementation have been given. An example of the development of a control program according to the obtained methodology is given.

The article discusses the features of debugging control programs. The possibilities of debugging control programs in various CNCs, both domestic and foreign, are analyzed. It was found that in many systems there is no collision tracking mode, and when simulating the execution of the control program, fixtures and tooling of the machine are not displayed. The structure of the control system is given and the connection between the control system and the interactive model is implemented. An interactive model of a CNC machine has been developed. The model receives signals from the CNC system. The movement of the model nodes is carried out according to the tasks from the CNC system. The work of the proposed solution is considered on the example of the automatic tool change mechanism. Implemented subroutines for the operation of the elements of the electric machine tool to control the change of tools. The proposed approach makes it possible to evaluate possible equipment collisions.
