Reduction of defects in the process of formation of precision surfaces of titanium alloy products

Abstract

Abstract The article proposes a new method of reducing defects in the process of formation of precision surfaces of titanium alloy products, which are significantly influenced by self-oscillation in the process of processing. The technique of controlling the amplitude of self-oscillations in the optical image of blanks with a digital camera of the light field and vibration parameters from the Doppler radar is presented. Studies have shown that the vibration signal from the surface of the product obtained by Doppler locator gives more complete information about the defects of the treated surface, information related to the process of formation of precision surfaces and the causes of self-oscillations. Optical method of control of self-oscillations on the basis of registration of a light field expands a range and accuracy of control of self-oscillations in 10 times. The configuration of the measuring scheme with parametric illuminator allows reducing defects in the process of formation of precision surfaces of products from titanium alloys. Studies have shown the possibilities of using vibration control to control the technological process to reduce defects in the process of forming the precision surfaces of titanium alloy products.
