Integrated Solution Comprises Fibersim And APV

Vistagy's Fibersim composites engineering software and Assembly Guidance Systems' (AGS's) Automatic Ply Verification (APV) system have been integrated. This integration is intended to enable users to quantify and document that hand-laid composite parts have been fabricated correctly. Inspecting each ply during the manufacturing process increases part quality, reduces costs, decreases cycle times and ensures that finished parts are true to the design.

Vistagy's Fibersim provides an end-to-end composites engineering solution that supports everything from analysis, design and manufacturing to quality inspection. As part of the solution, Fibersim automatically generates files from the 3D computer-aided-design model that control the laser projection system during ply layup. The integrated solution will enable users to simultaneously generate APV files, giving the operator a complete set of manufacturing commands.

APV is a feature of the Laserguide laser projection system from AGS and is used to direct the accurate layup of composite plies. APV replaces human inspection with an automated system. As an operator steps through the hand layup sequence with a Laserguide system, APV commands are automatically displayed when a ply inspection is specified. Laserguide projects the position for the operator to place a high-accuracy manually positioned inspector (Hampi) unit, which can verify material type, ply presence, sequence, location and fibre orientation and also detect foreign objects.

Laserguide will not proceed to the next pattern unless the inspection results fall within manufacturing tolerances. Scott Blake, president of AGS, said: 'By integrating APV and Fibersim, we have enabled the computer-generated precision of composite design to control the entire manufacturing process. 'The manufacturing engineer need only verify the tolerances that will be applied to the layup. 'That will lead to a less costly and time-consuming process,' he added.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
