Design of gantry-type milling machine

This master´s thesis deals with gantry – type milling machines. At first gantry – type milling machines are divided according to their structure. Then basic parts of an upper gantry – type milling machine are described. This machine is designed in a calculation part of this thesis. A calculation of a cutting force, a calculation of a needed moment of a drive of a spindle and a feed screw for axis x, y, z, a design of a belt drive between the spindle and the drive are done in the calculation part. Then the model of this upper gantry – type milling machines is made. Drawings are created for some parts of this machine
