Cutting tool technology term paper

Purpose of this paper is to show the benefits of implementation of management of cutting tools in the company which specializes in metal. Term tool management considers organization and implementation of a system which includes continuous activity monitoring, which are realized on two levels 1. • material cutting. In today’s fast paced, ever changing global manufacturing environment, the Management of the worlds production engineering and manufacturing resources are driven by several key forces: 1.1 Increased Production Demand. Without a doubt, the requirement to deliver more, in less time is present in most, if not all, manufacturing environments. From computer hardware to jetliners, to automobiles, to construction equipment, the overall global manufacturing environment is strong with all indications pointing to sustainable growth into the year 2000 and beyond. As a result of this increased demand, the "farming out" or "outsourcing" of the excess manufacturing load of larger manufacturing corporations has led to the growth of existing primary (tier I) and secondary (tier II) suppliers, some small in size, yet large in capability. Demands for information & answers in minutes not hours or days... In a previous survey of USA metalworking manufacturing companies conducted by Kennametal, Inc., it was predicted from the data that greater than 50% of the machine tool base in the USA was located in companies of 100 or less employees. It becomes evident that efforts and programs directed at the research and utilization of available technologies and processes to reduce production lead-times can pay great dividends in production output and customer satisfaction. This trend was expected to continue with the percentage approaching 65% by 2005. 1.3 Increased Machine Tool Utilization: One key contributing factor in achieving reduced manufacturing lead-times is getting more production out of existing machine tools by increasing their "uptime" or "chip making" time or "utilization". This trend represents a growing market in need of new machine tools and cutting tools and newer, more cost effective concepts and processes. Through surveys of several US based manufacturing organizations it was determined that the average machine tool "Uptime" (time in-process producing workpieces) was still below 60% and in several cases as low as 40%. In many cases the younger, smaller manufacturing companies, not slowed down by existing infrastructure, can be quicker to implement newer technology and gain from the benefits of today’s leading manufacturing concepts and communication tools. This would imply that, on average, a manufacturer could reduce that portion of the total manufacturing lead-time associated with "chip making" by 50% if they could more effectively utilize their machine tools.

High performance cutting (HPC) is used in machining railway parts like wheel sets or axes with large depth of cut and high feeds). The process is accompanied by increased thermal loads causing high concentration of stresses in the contact areas with the tool. This paper presents a set of methods to reduce thermal stress in machining zone in HPC conditions through the use of a special tool system, consisting of carbide cutting inserts with nano-structured multilayer composite coatings and a special scheme for mounting such inserts on tool holder with the use of high heat-conducting ceramic-polymer pads. The study has revealed that the developed tool system can significantly accelerate heat transfer from the insert and increase efficiency. Production tests show that the tool and the new coating in machining rolling stock (of railway) components can improve performance by 80-100%.

Water jet cutter - Wikipedia

Cutting tool technology term paper

A water jet cutter, also known as a water jet or waterjet, is an industrial tool capable of cutting a wide variety of materials using a very high-pressure jet of water, or a mixture of water and an abrasive substance. The term abrasive jet refers specifically to the use of a mixture of water and abrasive to cut hard materials such as. The salient features of a simple, wear-tolerant cemented carbide tool are described. Results are presented for high-speed machining (3 to 5 times the conventional speeds) of titanium alloys in turning and face milling. This tool, termed the ledge cutting tool , has a thin (0.015 to 0.050 in.) ledge which overhangs a small distance (0.015 to 0.060 in.) equal to the depth of cut desired. Such a design permits only a limited amount of flank wear (determined by the thickness of the ledge) but continues to perform for a long period of time as a result of wear-back of the ledge. Under optimum conditions, the wear-back occurs predominantly by microchipping. Because of geometric restrictions, the ledge tool is applicable only to straight cuts in turning, facing, and boring, and to face milling and some peripheral milling. Also, the maximum depth of cut is somewhat limited by the ledge configuration. In turning, cutting time on titanium alloys can be as long as ≈ 30 min.

Improvement of Working Efficiency of Cutting Tools by Modifying its Surface Properties by Application of Wear-Resistant Complexes

Cutting tool technology term paper

As a result, the tool life in machining of Ti6Al4V is substantially less than conventional materials such as steel and aluminium. This work reviews the various techniques employed in improving the machinability of Ti6Al4V alloy, from the perspective of cutting tool technology. The focus is onto the parameters affecting tool life. By Bill Koenig Senior Editor Makers of cutting tools for turning applications are having to innovate and improve their products amid tough times—the falloff in demand for tubing for the oil & gas industry, a key market. That means, among things, they must continue to up their game in finding ways to cut hard-to-machine materials such as Inconel and titanium while still working on tools—despite the decrease in demand—that produce better tubing that can be used to drill deeper in more isolated places.“As these materials are pushed to be stronger and more heat resistant, due to the depths they are going, the tube gets harder and harder to machine,” said John Winter, product specialist-turning of Sandvik Coromant (Fair Lawn, NJ), which has come out with Inveio, a new coating technology for steel turning and cast iron turning grades. “So the need for new cutting methods, new cutting material and new coatings is a must moving forward.”“The high strength and heat resistance of these alloys plays a huge role in cutting tool selection,” said Eric Jenkins, indexable tooling technical manager of Kyocera Precision Tools Inc. “Many factors have to be considered, including such things as the shape of the workpiece, the amount of stock removal and/or the presence of scale.”With nickel-based forgings, he said, “Customers can choose between different insert geometries as well as different categories of ceramics and carbides, depending on the specific details of the application.” “With the development of new materials like high-temp alloys, cutting tool manufacturers also have to develop new grades and geometries to machine and process these materials efficiently while providing long tool life,” said David Essex, turning product manager of Tungaloy America Inc. What’s more, all companies with ties to the energy sector are going to be called upon to do more.“Rapid changes in price, such as the halving of the oil benchmark between 20, naturally bring into focus the need for oil companies and their suppliers to reduce costs to maintain viable returns,” Paul Markwell, vice president of upstream oil and gas consulting and research at IHS Energy, said in a statement. “The first is in raising short-term production, the key denominator in the cost-per-barrel equation. The other involves attacking capital costs and operating expenses head on. “In general we can say: the tougher the material, the more difficult the machining, as the chemical makeup of the material creates higher cutting forces,” said Sandvik Coromant’s Winter.“For example, with chip control, you might get long stringy chips wrapping around the parts and tools,” he said. Both place an emphasis on efficiency.”Makers of cutting tools are looking to keep improving their offerings even while one of the drivers of their business—oil exploration—slackens. “High cutting speeds can cause sudden chipping, fracture of the cutting edge and built-up edge. Some alloys also work-harden easily, leading to diffusion-type wear and subsequently to excessive burr formations that make following operations more difficult.”Added Tungaloy’s Essex: “Customers come to us to help them solve manufacturing problems in processing difficult materials and we have to make sure our products provide those solutions.“Competition in the market requires that we stay on the leading edge,” he said. “Our focus is on developing new grades and geometries for accelerated machining.” The second issue to contront is evacuating chips resulting from cutting. “Turning encompasses both internal and external machining scenarios,” said Kyocera’s Jenkins.
