STUDY OF INSTRUMENTAL ADJUSTMENT IMBALANCE EFFECT ON MILLING OUTPUT PARAMETERS
The paper performs the analysis of the main requirements to tools balancing and experimental evaluation of the effect of the class of instrumental adjustment balancing on the output characteristics of milling. The latter serve the basis for formulating of major recommendations on the balancing quality of end mills. It has been experimentally determined that the requirements for instrumental adjustment balancing imposed by the producers of motor spindles for milling machines are excessive, while the transition (when evaluating the balancing quality) from the ISO 1940/1 standard to the new DIN 69888 standard is technologically and economically justified. It is found that the class of instrumental adjustment balancing in accordance with the requirements of ISO 1940/1 does not have a decisive effect on the output parameters of high-performance milling.
