Bank Of Algeria Mint Invests In CAD CAM Technology

The Bank of Algeria Mint has invested in equipment and methods from Sescoi to help it respond to the demands of modern banking and to encourage the growth of the country's economy. The tooling department needed a computer-aided-design (CAD)/computer-aided-manufacturing (CAM) system to help it improve its range of capabilities and shorten lead times. The Bank of Algeria purchased WorkNC from Sescoi in 2006.

The assistant director at the Bank of Algeria Mint said: 'We have a wide range of CNC milling and turning machines and we needed to modernise in order to achieve just-in-time manufacture, respond to urgent requirements and machine increasingly complex and intricate shapes.' Before the introduction of WorkNC, programming was carried out on the machine tool control, which required high levels of skill from the operator, reduced the available capacity and the productivity of each machine and limited the complexity of the parts being produced.

WorkNC-CAD is used to design existing or new components and parts using its recently incorporated parametric solid modelling. Furthermore, the WorkNC-CAD turning module is said to make CNC lathe machining easy and reliable. For machining and engraving, the bank uses WorkNC to create programs from two axis right through to the full five axis. The assistant director said: 'We program all our CNC machines with WorkNC for the milling of simple or complex parts.

'We have optimised our production processes and achieved productivity gains of more than 60 per cent.' For its five-axis programming, the Bank of Algeria uses WorkNC's Auto 5. Unique to Sescoi, the software automatically translates three-axis toolpaths into five-axis toolpaths, making five-axis machining as simple to program as three-axis machining, with reliable and collision-free toolpaths. Using the technology gives the bank the advantages of using short rigid cutters and the ability to reach more of the part in one setting, resulting in improved surface finish and shorter machining times.

Sescoi's five-axis routines include collision-avoidance algorithms, which consider the limits of the individual machine tool, introducing unwind and flip movements so that machining can continue safely and uninterrupted. The assistant director said: 'The ease of use of Auto 5 has enabled us to adopt five-axis machining methods very quickly. 'We find that the toolpaths it creates for our five-axis machines are completely reliable and we anticipate purchasing more licences in a few weeks.' The bank invests in a continuous training program with Sescoi, ensuring that its engineers can fully exploit WorkNC's capabilities, benefit from the support hotline and receive software upgrades.

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.
