The timely chip evacuation from the cutting zone is of the utmost importance due to the possibility of repeated chip cutting, which is actually abrasive. The authors proposed three main schemes for forced chip removal from closed T-shaped slots: due to the forced removal of chips from the space between the teeth of the cutter (supply of a lubricating-cooling technological medium through the channels in the tool body); due to the forced removal of chips from the space outside the cutting tool (cooling agent supply through the channels of the external nozzle); a combination of the two previous methods. The theoretical foundations of the proposed chip removal devices have been developed to determine the rational parameters of their functioning based on five mathematical models. Confirmation of the reliability of the developed theoretical provisions and the adequacy of the created mathematical models requires appropriate experimental studies. When conducting experimental studies, mechanical processing of T-shaped grooves 12 in steel and cast iron blanks was performed. For this, milling cutters with a diameter of 21 mm were used for processing cast iron and with a diameter of 21 mm for processing steel 45. Verifying the hypothesis about the adequacy of the developed mathematical models is carried out using the Fisher F-criterion. The simulation error is estimated by calculating the absolute and relative errors of the mismatch between the theoretical curve and the curve approximating the experimentally obtained data.
