摘要:
A bevel gear drive with two bevel gears rotates about respective rotation axes intersecting at an intersection point, forming an angle of intersection. A computer determines the tooth shape of these tooth flanks based on data other than a tooth shape. The data are characteristic for a particular contact path represented by a sequence of contact points. The tooth shape of the tooth flanks is determined for several contact paths, with the interacting tooth flanks at all contact points having a common normal, which passes through a pitch point located between the two rotation axes and spaced from the intersection point equal to the radius r. Geometry data for the bevel gear are determined from the shape of the tooth flanks and stored in a format suitable for automatically generating a parts program for a processing machine with at least five axes.

The invention relates to a method for guiding the movement of a movable machine element (8) of a numerically controlled tool machine or production machine on a predetermined movement path (s) of the machine element (8). Supporting points (32) are defined in the working area (31) of the machine. The maximum possible path jerk () and/or the maximum possible path acceleration ({umlaut over (s)}) and/or the maximum possible path speed ({dot over (s)}) of the machine element (8) is determined or predetermined at on each supporting point (32) and the movement of the machine element (8) on the displacement path (S) is carried out using the maximum possible path jerk () and/or the maximum possible path acceleration ({umlaut over (s)}) and/or the maximum possible path speed ({dot over (s)}) of the machine element (8). Said method can be produced in a simple and economical manner with optimum guiding of the movement of a movable machine element (8) of a numerically controlled tool machine or production machine on a predetermined movement path (S) of a machine element (8).

A device and method for apportioning a movement of a machine element driven by at least two drives for movement along a drive axis of a machine tool or production machine are described. A low-pass filter filters predetermined desired drive axis values to generate filtered desired drive axis values, with a first controller receiving the filtered desired drive axis values as control input value for controlling a first of the at least two drives. A delay unit with a constant group delay time temporally delays the desired drive axis values and generates delayed desired drive axis values, whereafter a subtracter determines a difference between the filtered desired drive axis values and the delayed desired drive axis values. A second controller receives the determined difference and provides, based on the determined difference, a second control input value for controlling a second of the at least two drives. With these features according to the invention, a movement of a machine element along a drive axis of a machine tool or production machine can be optimally apportioned between two or more drives.

According to the invention, a simulation is carried out based on the fundamental motion equation (1) for simulating the system by means of: transformation of the fundamental motion equation into linear differential equations of the first order; further transformation of the linear differential equations into time-discrete state variables; determination of the time response of the system by actualization of the resulting algebraic differential equations in the sampling raster of an associated control processor. Higher simulation accuracy is obtained at an essentially smaller calculating capacity.

The invention relates to a method for displacably guiding a displaceable machine element (8) of a numerically controlled tool machine or product machine on a predetermined displacement path (S) of a machine element (8). Supporting points (32) are defined in the work chamber (31) of the machine. The maximum possible path bolt (S ) and/or the maximum possible path acceleration (S ) and/or the maximum possible path speed (S ) of the machine element (8) is determined or predetermined on each supporting point (32) and the displacement of the machine element (8) on the displacement path (S) is carried out using the maximum possible path bolt (S ) and/or the maximum possible path acceleration (S ) and/or the maximum possible path speed (S ) of the machine element (8). Said method can be produced in a simple and economical manner with optimum displacement guiding of a displaceable machine element (8) of a numerically controlled tool machine or production machine on a predetermined displacement path (S) of a machine element (8).

A pointer is guided by a user of a processing machine in succession to a number of locations of a working space of the processing machine. The pointer has first location determining devices which are arranged at predetermined pointer locations relative to a pointer coordinate system in fixed relationship to the pointer. Through interaction of the first location determining devices with second location determining devices arranged at predetermined locations relative to a machine coordinate system in fixed relationship to the processing machine, data describing a geometric relationship of the location determining devices relative to one another are acquired. These data are transmitted to a control device which determines the position of the pointer in the working space based on the characteristic data and based on the data subdivides the working space into a permitted movement range for a component of the processing machine and a complementary prohibited movement range.
