The article focuses on a new way to solve the problem of cutting processing due to the appearance of a wide range of super-
hard and hard-to-machine structural materials for aircraft, automobile, ship and engine construction, as well as for spacecraft, medi-
cine (orthopedics, dentistry), nuclear and military equipment. Such materials have an organized regular structure, high strength, super
hardness. As a result, there is a problem of defect-free machining of these materials without damaging their balanced structure. The
article describes a new approach and formulates innovative principles for creating a new class of mechatronic technological systems
for precision machining of parts made of these materials using the example of drilling small diameter deep holes. The core of the
mechatronic technological system is a mechatronic parametric stabilizer of the power load on the cutting tool. The mechatronic tech-
nological system provides a program task, automatic stabilization and maintenance in the tracking mode of the power load on the
cutting tool with “disturbance control”. For example, in the technological cycle of drilling small diameter holes, such a system pro-
tects the drill bits from breakage. An integrated technological system is proposed with the following three levels of control: intelli-
gent (upper), adaptive (middle) and robust (lower). The basis of the multi-level system is a high-speed robust automatic control sys-
tem “by the disturbance”. The disturbance is the load torque, which is either automatically stabilized, or tracked when setting a pro-
gram from a computer, or changes according to the program that sets the mechatronic technological system the functioning (opera-
tion) algorithm. This algorithm can vary widely with different methods of machining parts by cutting (grinding), including shaping
free 3D surfaces according to their digital models. The mechatronic technological system proposed is easily integrated into the cut-
ting (grinding) system of CNC machines, expanding their capabilities by transferring the standard control program of the CNC to a
higher level of the control hierarchy. This allows machining any complex-shaped parts, including “double curvature” parts, namely
impellers, turbine blades, rowing screws, etc.
