The problem of punching tools resistance increasing is investigated. Methods for intermetallic coatings synthesis are investigated. Mathematical model of vacuum ion-plasma deposition process allowing predicting coatings composition basing on intermetallic system Ti-Al was developed. Experimental verification confirmed the adequacy of the computer model. The technology hardening punching tools with wear-resistant coatings deposition based on intermetallic Ti-Al system on pre-nitriding surface in vacuum was developed. Production tests of the hardened punching tools were carried out.

An analysis of the dynamic and stability characteristics of a guided wood cutting spline arbor circular saw is presented. A multibody dynamic model is developed to consider the idling and cutting characteristics. The model considers the interaction between the blade, the arbor, and the guide pads. The model is capable of analyzing in-plane and out-of-plane edge forces which enables simulation of the cutting performance of the saw. In order to verify the computer model, an experimental test of a guided spline saw during idling run-up is presented. The frequencies and amplitudes of the blade vibrations are documented and plotted. Cutting tests are also conducted and the cutting forces are estimated. The results of a simulation of the idling response of the blade by the computer model and the experimental results are in a good agreement. Factors that significantly affect the characteristics of guided spline saws during cutting are discussed. The computer model is shown to be capable of predicting stable cutting operations of a guided spline saw.

A Direct Method

Though theoretical analysis and experimental verification, a direct method that measuring melt pressure fluctuation at the nozzle to reflect melt viscosity fluctuation in injection molding process was developed. Experiments for four injection molding screws and the analysis for the relationships between the melt viscosity homogeneity and screws configuration, melt temperature homogeneity, repeating weight precision and mechanical properties of the injection molding parts were conducted. At last, the four injection screws were evaluated based on melt viscosity homogeneity method.
