An experimental investigation of vibration characteristics in the diamond wire sawing of granite

Introduction

An experimental investigation of vibration characteristics in the diamond wire sawing of granite. Study vibration characteristics in diamond wire sawing of granite. This experimental analysis measures signals at six points, revealing a U-shaped amplitude distribution and parameter influences.

Abstract

Compared with circular and gang sawing, diamond wire sawing is a flexible machiningmode due to its special structure characteristic. The diamond wire with the elastic steelcore bends and vibrates in sawing process. In this paper, the vibration characteristicsare analyzed in the granite sawing with the diamond wire. The vibration signals in thesawing process are simultaneously measured at six different measurement pointsalong the cutting zone. The influences of sawing parameters on the vibrationcharacteristics are explored. The results show that the vibration amplitude is aU-shaped distribution in the sawing arc. The vibration amplitude decreases with theincrease of wire speeds, feed rates and the tension forces. The vibration fundamentalfrequency is certainly proportional to the number of wheel speed times the number ofbeads per meter, which has no related to the feed rates and tension forces in the sawprocess. The wire vibration indicates the impact of bead acted on the workpiece.

Review

This abstract presents a focused experimental investigation into the vibration characteristics encountered during the diamond wire sawing of granite, a process noted for its flexibility in machining hard materials. Understanding these vibrations is critical for optimizing sawing efficiency, tool life, and the quality of the cut surface. The authors aim to analyze these characteristics and explore the influence of various sawing parameters, which represents a valuable contribution to improving the industrial application and performance of diamond wire sawing technology. The methodology described involves the simultaneous measurement of vibration signals at six distinct points along the cutting zone, suggesting a comprehensive approach to capturing spatial variations in the vibration behavior. The key findings are clearly articulated: a U-shaped distribution of vibration amplitude along the sawing arc, and a decrease in amplitude with increasing wire speeds, feed rates, and tension forces. Crucially, the abstract also identifies that the fundamental vibration frequency is directly proportional to the product of wheel speed and the number of beads per meter, independent of feed rates and tension forces. These results provide significant insights into the dynamic interaction between the diamond wire and the granite workpiece. While the abstract effectively summarizes its core findings, a full paper would greatly benefit from further elaboration on several aspects. Specifically, detailing the precise types of vibration signals measured (e.g., acceleration, displacement) and the instruments used would enhance methodological clarity. A deeper mechanistic explanation for the observed U-shaped amplitude distribution would be particularly insightful. Furthermore, expanding on the practical implications of these findings—how they can inform process optimization, mitigate tool wear, or improve surface finish—would significantly strengthen the paper's impact and relevance to both academic research and industrial practice.
