• Classification of Machine Tools (1)

  5/13/2010
  
  There are many ways in which machine tools can be classified. One classification based on production capability and application is given in the following lines.
  
  
  General Purpose Machine Tools(GPM)
  
  
  These tools are those designed to perform a variety of machining operations on a wide ranging type of components.
  
  
  By its very nature of ..

• About Servomechanism (2)

  4/13/2010
  
  
  A common type of servo provides position control. Servos are commonly electrical or partially electronic in nature, using an electric motor as the primary means of creating mechanical force.
  
  
  Other types of servos use hydraulics, pneumatics, or magnetic principles.
  
  
  Usually, servos operate on the principle of negative feedback, where the contro..

• About Servomechanism (1)

  4/6/2010
  
  A servomechanism, or servo is an automatic device that uses error-sensing feedback to correct the performance of a mechanism.
  
  
  The term correctly applies only to systems where the feedback or error-correction signals help control mechanical position or other parameters. For example, an automotive power window control is not a servomechanism, as there is no automatic feed..

  The controllers have a number of modes in which they operates. There can be four possible modes in which the controller can function in relation to a machining center.
  
  The first shows a typical drilling machine operation, termed as point-to-point mode. In this, the control has the capability to operate all the three axes, but not necessarily simultaneously. As a result, it woul..

  At present, CNC machining center appears to be the most capable and versatile automatic machine tool that can perform drilling, tufting, milling, boring, reaming and tapping operations.
  
  
  The general objective behind the development of CNC machine tools continues to remain the reduction of cost of production by reducing the production time. This in turn is directed toward..

• CNC & Laser Cutting

  1/18/2010
  
  An advanced use of CNC technology is the use of laser for cutting and engraving to produce intricate patterns and motifs, such as arch cuts on raised panels for cabinet, passage doors and windows. The marriage of laser and CNC functions offer the advantages of both technologies in one system.
  
  For example, Epilog Laser offers a standalone unit, the Zing Starter Series, for engra..

  With skilled craftsmen dwindling in numbers, CNC machines quickly becomes the technology of choice for large and small woodwork shops.
  
  Computer Numerical Control (CNC) is for operating machine tools with computer programmed instructions. They are keyed into a computer and sent to automatic devices; typically rotary servo mortors driving ballscrews, or other mechanisms such as a..
