Vibration is a continuous cyclic motion of a structure or a component Generally engineers try to avoid vibrations because vibrations have a number of unpleasant effects • Cyclic motion implies cyclic forces Cyclic forces are very damaging to materials • Even modest levels of vibration can cause extreme discomfort • Vibrations generally lead to a loss of precision in controlling

vibration free operation and best machining accuracy The top of the base is similar to a worktable and maybe equipped with T slots for mounting work too large for the table CARE OF DRILLING MACHINES Lubrication Lubrication is important because of the heat and friction generated by the moving parts Follow the manufacturer s manual for proper lubrication methods Clean each machine after
Frequency is a measure of how fast a body is vibrating and is used to identify the source of vibration Normally Frequency is expressed in shaft rotative speed If a vibration is at the same frequency as the shaft speed this will be 1X or 1 time shaft speed If it is twice it is 2X Also the frequency may be expressed in cycles per second or Hertz or in cycles per minute The …
Machining vibrations also called chatter correspond to the relative movement between the workpiece and the cutting vibrations result in waves on the machined surface This affects typical machining processes such as turning milling and drilling and atypical machining processes such as A chatter mark is an irregular surface flaw left by a wheel that is out of true in

In vibration welding two plastic parts are in frictional contact with each other with a certain frequency amplitude and pressure As a result of the friction between both parts heat is generated which causes the polymer to melt at the interface Due to pressure the molten polymer flows out of the weld zone giving rise to flash see Figure 1 After the vibration has stopped the layer of
