Information at the Cutting TECHNOLOGY FEATURE: LANDING GEAR INFORMATION AT THE CUTTING EDGE Heavy-duty cutting of exotic alloys can place huge requirements on a CNC machining centre and its working envelope when manufacturing landing gear components. WFL Millturn Technologies says its competence in this area reaches the parts other machining centres cannot reach. Mike Richardson reports.

Depending on the machine size, the company says it can offer between three and 18 of these long tools in a special magazine alongside the typical line-up of chamber boring tools and live boring heads. As part of WFL’s focus on internal machining technologies, it formed a partnership with Sandvik Coromant to examine the use of an ‘intelligent tool’ on the M120 MILLTURN at last year’s EMO Hanover event. In light of the ever- increasing importance of networking, a live demonstration of the functionality of the intelligent 18xD CoroPlus boring bar was conducted by the WFL team to interested visitors. 4218 FebruaryOctober 2013 2018 www.aeromag.com Aerospace Manufacturing www.aero-mag.com Here, the boring bar is integrated into a special WFL prismatic toolholder which included a data interface. Thanks to the CoroPlus technology, information and tool statuses can be transmitted to the control system or a tablet. During processing, the machine operator is provided with information regarding temperature, deviations, background noises, vibrations and the load on the tool. In this way, the chip removal process can be perfectly optimised, protecting both tool and workpiece from damage. In addition, the complete process can be logged in full.

Basic functional principles of machine tool operations Machine Tools produce desired geometrical surfaces on solid bodies (preformed blanks) and for that they are basically comprised of; • Devices for firmly holding the tool and work • Drives for providing power and motions to the tool and work • Kinematic system to transmit motion and power from the sources to the tool-work • Automation and control systems • Structural body to support and accommodate those systems with sufficient strength and rigidity. For material removal by machining, the work and the tool need relative movements and those motions and required power are derived from the power source(s) and transmitted through the kinematic system(s) comprised of a number and type of mechanisms. (i) Concept of Generatrix and Directrix • Generation of flat surface The principle is shown in Fig. 2.1 where on a flat plain a straight line called Generatrix (G) is traversed in a perpendicular direction called Directrix (D) resulting a flat surface. • Generation of cylindrical surfaces The principles of production of various cylindrical surfaces (of revolution) are shown in Fig.

  • Vibrations in Metal Cutting Measurement, Analysis and Reduction
    Vibrations in Metal Cutting Measurement, Analysis and Reduction Linus Pettersson Ronneby, March 2002 Department of Telecommunications and Signal Processing Blekinge Institute of Technology 372 25 Ronneby, Sweden c Linus Pettersson Licentiate Dissertation Series No. 01/02 ISSN 1650-2140 ISBN 91-7295-008-0 Published 2002 Printed by Kaserntryckeriet AB Karlskrona 2002 Sweden v Abstract Vibration and noise in metal cutting are ubiquitous problems in the workshop. The turning operation is one kind of metal cutting that exhibits vibration related problems. Today the industry aims at smaller tolerances in surface finish. Harder regulations in terms of the noise levels in the operator environment are also central. One step towards a solution to the noise and vibration problems is to investigate what kind of vibrations that are present in a turning operation. The vibrations in a boring operation have been put under scrutiny in the first part of this thesis. Analytical models have been compared with experimental results and the vibration pattern has been determined. The second part of the thesis deals with active vibration control in external turning operations. By embedding a piezo-ceramic actuator and an accelerometer into a tool holder it was possible to obtain a solution that can be fitted in a standard lathe. The control system consists of the active tool holder, a control system based on the filtered-X LMS algorithm and an amplifier designed for capacitive loads. The vibration level using this technique can be reduced by as much as 40 dB during an external turning operation. vii Preface The work presented in this licentiate thesis has been performed at the department of Telecommunications and Signal Processing at Blekinge Institute of Technology.

  • Design, Construction, and First Tests of a Demonstration Spark Chamber
    Design, Construction, and First Tests of a Demonstration Spark Chamber Lisa Lin,∗ Robin Peter,y Sophia Vlahakis,z and Tara Vogelx The University of Chicago, Illinois, 60637 (Dated: September 21, 2018) Once used extensively in particle physics research, the cosmic ray spark chamber is a tracking particle detector now favored for education and demonstration. We have constructed and are nearing installation of a chamber for educational and demonstration purposes, selecting a shelf-type design to prioritize aesthetic appeal and minimal maintenance. An incoming particle triggers a fast high- voltage pulse to metal plates within the chamber that allows sparking along the particle's ionized path. The shelf-style design and careful scintillator placement limits spurious edge sparking. The coincidence circuit comprised of scintillation counters and NIM units successfully delivers a logic pulse within 60 ns, and its 1.3-V pulse is amplified ten-fold in a total delay time of 500 ns from detection to spark gap pulse, triggering an 8-kV pulse in the chamber. The prototype chamber is tested independently with helium and argon gases. A plan is presented to predict lifetime based on the muon efficiency of the prototype chamber. Initial stages of an interactive soft-shut off are presented for safety and consideration of the chamber demonstration's surrounding academic environment. I. INTRODUCTION nents for a similar purpose; we have used their proce- dure as an initial guide [1]. This document tracks our Spark chambers have been used in the past as tracking major considerations, revisions, and additions to their particle detectors, and are most widely used today for work, and presents that information for the perusal and educational purposes [1].
