Wire Analysis and Control for Precision EDM Cutting, Sodick high precision wire EDM filters manufacturer This paper deals with wire EDM machining accuracy, in particular, how the cutting precision and accuracy can be improved by suitable detection techniques and control algorithms. In a first paragraph, it is shown that the wire vibration problem can be described by mathematical models. The main part of the paper is

Wire EDM Improves Throughput, Surface Finish, wire EDM Filters For many American manufacturers, the threat of overseas competition merits constant attention. In fact, many plan their operations with an eye toward maintaining a competitive position relative to foreign manufacturers. One such company is Precision Stampings, Inc. (PSi). Among other strategies, a commitment to routinely investing in new technology for th

NC verification for wire-EDM using an R-map, wire cut EDM Filters manufacturer Abstract Due to the high complexity and the low speed of the wire-EDM process, it is important to recognize all the possible errors before starting the process. The unproductive and time consuming test runs of wire-EDM NC programs in the real production environment can be avoided by computer graphic simulation. In this paper, a data struct

Impact of Wire-EDM on Tribological Characteristics of ZrO2-based Composites in Dry Sliding Contact with WC–Co-Cemented Carbide,wire EDM filter supplier Abstract The effect of surface conditions and secondary phase addition on the dry sliding friction and wear characteristics of five yttria-stabilized ZrO2-based composites with 40 vol% WC, TiCN or TiN was investigated using an ASTM G133 pin-on-flat sliding contact con

An energy-distribution strategy in fast-cutting wire EDM, wire EDM Filters supplier Abstract The technical requirements of fast-cutting wire EDM are revealed in this paper. In addition to high input pulse energy, fast cutting (cutting speed > 200 mm2/min) without damaging the electrode wire needs a high energy efficiency for maintaining a stable fast-cutting process and moderate wire temperature. Based on a synthe

Digraph and matrix method for the performance evaluation of carbide compacting die manufactured by wire EDM, Quality EDM Filter manufacturer Abstract This paper presents a methodology to evaluate the performance of carbide compacting die using graph theoretic approach (GTA). Factors affecting the die performance and their interactions are analysed by developing a mathematical model using digraph and matrix method. Pe

This paper deals with the implementation and analysis of real-time energy monitoring of the transient state of the wire electrical discharge machining (WEDM) process. Recently, sparking frequency information has been applied to control of the WEDM process, making more stable and efficient machining. Experimental results, however, show the limitations and insufficiency of that method. Instead of using the sparking fre

New EDM Wire Is Tough To Break |  Wire EDM filter supplier In many aspects of life, the characteristics of strength and toughness are thought to be synonymous, and indeed that is often the case. However in the world of wire EDM, considering strength and toughness to be synonymous can result in a fair measure of disappointment when one is struggling with wire breaks caused by less than ideal flushing conditions. Howev

Abstract In this paper, a closed-loop wire tension control system for a wire-EDM machine is presented to improve the machining accuracy. Dynamic models of the wire feed control apparatus and wire tension control apparatus are derived to analyze and design the control system. PI controller and one-step-ahead adaptive controller are employed to investigate the dynamic performance of the closed-loop wire tension control
