Method and device for axis control for machine tools and the like

A method for controlling the axes of motors, for machine tools and the like, including the steps of: calculating, from a sequence of relative position data of each axis and of actuation states at each definite instant, a path for each individual axis, starting from parameters of initial speed, number of steps and final speed; defining a three-dimensional matrix that contains, for each axis, initial speed, number of steps and final speed, each element of the three-dimensional table, constituted by the intersection in space of the three parameters, containing an address that is suitable to point to the vector which describes a corresponding waveform; driving the axis according to the waveform.

Spring collet for machine tools

In a spindle assembly for machine tools, the axial length .lamda. of the collar of a spring collet is determined as a function of the axial course length c of a clamping sleeve operating spring collet. This axial length .lamda. is preferably retained within an interval ranging between 3 mm and 9 mm. A tapering surface of the collar presents an inclined profile, which is straight, curved, or at least partially curved. The angle of inclination formed by the tapering surface with the axis of the spring collet is advantageously of the order of 45.degree.. The spring collet has at least two grooves. The gap between these grooves may be determined in such a way that, when the spring collet is in the closed position, then the workpiece is gripped with a predetermined clamping force, and the two mutually opposing faces of each groove portion abut against each other.

Device for automating and/or controlling of machine tools or production machines

A device for automating and/or controlling machine tools or production machines is described. The device includes at least one computer which is located remote from a machine. The computer operates like a handheld controller and is connected via at least one bus system, which can be wired or wireless, with each machine for unidirectionally or bidirectionally transmitting data and control signals. All control functions of the machine are integrated in the remote controller. This device can automate and/or control machine tools and production machines in a simple and cost-effective manner.

Control structure for the active damping of low-frequency oscillations in numerically controlled machine tools

A control structure for the active damping of low-frequency oscillations in numerically-controlled machine tools. The control structure includes an rpm regulator having a proportional component and an integral component. The control structure further includes an active damping element that forms a low-frequency correction signal, which is phase-shifted with respect to an interfering low-frequency oscillation and free of d.c. components, and a summing point that is upstream or downstream of the integral component and receives the low-frequency correction signal.
