“…The RUM process involves material removal by hybrid action of ultrasonic stationary machining (USM) and conventional grinding [2]. In the process, accuracy and material removal rate are affected by tool wear [3,4]. Tool wear is a complex phenomenon in USM and usually involves loss of tool volume and dulling of abrasive grains.…”

“…Tool wear is a complex phenomenon in USM and usually involves loss of tool volume and dulling of abrasive grains. It occurs mainly due to tool change at micro-level topography than that at tool profile [3,4]. Tool wear is a major challenge in rotary ultrasonic machining, and it is more significant in case of micro-rotary ultrasonic machining.…”

Tool wear in micro-manufacturing process is of paramount importance to meet stringent design requirements of workpiece in a cost-effective manner. In present work, tool wear in micro-rotary ultrasonic machining (μ-RUM) has been investigated for Ø300-μm peck drilling operation. Two sets of experiments have been conducted using electroplated hollow diamond tool and borosilicate glass as workpiece to evaluate the effects of μ-RUM parameters on tool wear. In the first set, the effects of tool-based parameters like grain size and thickness of hollow tool have been studied using full factorial design and optimum tool design was obtained. In second set, the effects of process-related parameters like spindle speed, distance traverse in each stroke, table feed rate, vibration amplitude, and vibration frequency on tool wear were studied using central rotatable composite design with optimum tool designed in first step. Analysis of variance has been used to study the significance of μ-RUM factors on tool wear . After investigation and analysis of the data, it has been concluded that thickness and grain size of hollow diamond tool had an inverse effect on tool wear. Tool with 100-μm thickness and 30-μm grain size was best possible tool for minimum tool wear. It has also been found that process parameters like traverse in each stroke, vibration amplitude, vibration frequency, and spindle speed have affected tool wear, but vibration frequency was most influencing process parameter and resulted in rapid tool wear if not selected properly.

“…In the case of electrode wear, it was observed that the most influential is pulse off time, followed by the peak current. Research have been attained to assess the effect of three factors-tool material, grit size of the abrasive slurry and power rating of ultrasonic machine on machining characteristics of titanium (ASTM Grade I) using full factorial approach for design and analysis of experiments 12 . It has been reported that the MRR depend on the tool material From the literature study, it was appeared that the EDM performance characteristics are greatly reliant with work and tool materials.…”

“…Kinematics of these processes covers conventional process and assisting factor in the form of oscillatory tool or machining workpiece with a small amplitude and frequency of the ultrasonic, a small amplitude and frequency of the ultrasonic resulting from the reverse piezoelectric effect or magnetostriction. Of particular note is the process of ultrasonic assisted grinding which is applying to the machining of hard, ductile and brittle materials, for example technical ceramic, sintered carbide, quartz [1][2][3][4][5][6][7][8][9], and also different constructing material as steel [10][11][12], nickel alloys [13,14] or titan alloys [4,[15][16][17][18]. There are two main types of such process: ultrasonic assisted grinding with tool oscillation and ultrasonic assisted grinding with workpiece oscillation.…”

This article presents the grinding tools designed to serve hybrid machining process -ultrasonic wheel vibration assisted grinding. It describes possibilities of using of different abrasives, grinding wheel clamping systems and holders with ultrasonic oscillation inductor. Realization of Ultrasonic Assisted Grinding (UAG) process is possible on machines with special design. Most machine tools are manufactured on the basis of conventional ones and are retrofitted with ultrasonic vibration system. There are two types of tool holders designed for this machine tool: holders for hybrid machining processes (ultrasonic actors) and holders for conventional processes. Each type of tool holder is fixed to the spindle with hollow taper shank. The tools are attached to the ultrasonic actors by screw and positioned on arbor, or by the collets. For the UAG process tools made of various abrasives are applicable. Binding material, the concentration of abrasive grains and their size may differ. It is possible to use diamond or cubic boron nitride tools and also tools made of conventional abrasives. Ultrasonic Assisted Grinding is a novelty in the field of manufacturing techniques. It is necessary to conduct detailed investigations of this process. The factors that have a significant impact on the UAG results for different materials, the oscillatory motion parameters in relation tool or workpiece as well as on the dressing tool should be investigated.
