Machine Parts

The requirements of machine tools are given bellow: 1.       Strength static is high. 2.       Dynamic rigidity. 3.       Shape and layout of machine tool should be a.       Facilitate easy chip removal. b.       Machining operation should be easier. c.       Observation of cutting operation should be safe. d.       Assembly should be easy and dismantling. e.       For maintenance accessibility should be easy. 4.        Economic consideration. 5.       Transportation and installation should be easiest. 6.       Aesthetic appeal. 

1.       The starting characteristics. 2.       The requirement of speed regulation. 3.       The torque and the power characteristics with respect to the shaft speed. 4.       The cost economy. 5.       The need t o breaking. 6.       The dynamic vibration such as vibration. 7.       The advantage of electrical energy. 8.       The efficiency including the operating condition. 9.       The robustness of motor.                                    Electrical Drive System     Fixtures and Economics     Whats way Walk Energy in Future?   What is Sheet cutting shearing machine, Combining shearing machine and Sheet bending machine?   Ceramic Membrane Material Synthesis and Testing Objective   China ready to land robot rover on Moon                                          Benefits of Membrance Reactor for Hydrogen Production from Biomass   Hydrogen Production Cost from Bi

  A fixture for production machining must be considered like any other machine tool. It should pay for itself from the savings derived from its used. The tool designer may be required to designer the cost of a fixture and whether its construction will be profitable in the early stages of fixture design. The cost and return can not be determined exactly because of the variables that may enter into the overall picture, but a close estimate can be made from formulas developed for this purpose.   The economic aspects of the use of a fixture can be considered of the following basic: 1.       The production per year necessary to pay out of savings for a fixture of given estimated cost. 2.       The maximum allowable cost of a fixture to break even for a given saving in operating cost per price and specific cost given yearly production. 3.       The number of years will take to pay out of savings for the proposed fixture with given savings operating cost per price an
