According to the motion characteristics of 4-axis CNC machine tool, this paper studies a new way for manufacturing the mushroom turbine blade boot .It must rotate the turbine blade to ensure the tool axis consistent with the normal of the interpolating point on the arc of the blade boot, and move the tool to keep the cutting point in contact with the interpolating point. Meanwhile, this paper researches an algorithm to calculate the tool path in the MCS, According to this algorithm, a program with R variable parameter for manufacturing the mushroom turbine blade boot is provided.

Stiffness And Damping

A generalized eigenvalue method is used to determine the undamped and damped natural frequencies, coefficients of damping and mode shapes of a computer numerically controlled (CNC) machine tool drive. The calculated results compare well with the measured results obtained by using vibration analysis equipment. Then the sensitivity of the various modes to changes in the stiffness and damping characteristics of the machine drives is estimated. These values prove to be useful in adjusting the parameters of a hybrid model for a CNC machine tool axis drive in order to alter the simulated results in accordance with the measured results.

Dc Servomotor

This paper presents some simulation based upon a dynamic model of a feed-drive within the structure of a CNC machine tool. A DC servomotor was considered as actuation device for the feed drive. For a given set of parameters for the position controller, two fuzzy types of fuzzy controllers were tested by means of simulation. The first fuzzy controller was a proportional one, with one input and one output, while the second one was a two variables one, with two inputs and one outputp.
