Abstract: The technique bonding metal to metal using epoxy resin adhesive has been employed since 1930's and found its successful applications in the aircraft industry. However, the application of bonding technipue to machine tool structure has been explored recently. In this field, much work has been carried out towards the design and static and dynamic characteristics of bonding structure. All those work has proved that the application of ,bonding structure to machine tool improve the dynamic performance.The structure of a horizontal milling machine, including column, base and overarm was manufactured according to this technique. The dynamic performance of this machine as determined by dynamic and cutting tests was compared with those of a cast iron milling machine. In the chatter tests two types of- cutter were used. For the bonded milling machine, the rate of metal remnoval, at the onset of chatter, has been 'shown to be substantially higher 'than that achieved on the cast iron milling machine. Also in this -paper the reliability of the dynamic testing technique has been assessed in comparison with the cutting tests.
