Problems solved by technology

However, when a reliable path is moved in order to avoid conflicts, for example, after the end of the action, the relevant tool is first moved to a so-called safe rest position, and then the starting position of the following action is moved from this rest position or another rest position, This results in long travel distances and long positioning times

Embodiment Construction

[0021] exist figure 1 A grinding machine 1 is shown in an extremely simplified schematic diagram. The machine tool has a grinding head 2 with a grinding tool 3, for example a grinding wheel. The grinding head 2 can be adjusted in multiple directions, for example in three directions X, Y, Z. For adjustment, corresponding drive units 4 , 5 , 6 are used, which are connected to a control unit 7 via control lines. This control device is formed, for example, by a machine control computer, which is connected to a memory 8 . In addition, the grinding machine 1 has a workpiece holder 9, in figure 1 In order to illustrate, a rod-shaped blank 11 is supported in the workpiece fixture. The workpiece holder 9 can be mounted rotatably about an A axis, for example. A corresponding drive unit 12 is connected to the control unit 7 . If the grinding head 2 can only be moved in the Y and Z directions, the workpiece holder 9 can also be moved in the X direction. The drive device 4 is now co...

Abstract

In order to determine the time-advantageous conflict-free travel, the machine tool control of a grinding machine is provided with a database (D) available for each discrete coordinate point (X, Y, Z, A) and for discrete Each combination of the tool model (WZI) and the tool model (WSJ) has a collision parameter 0 or 1. This collision parameter indicates whether the state, ie the relative position, of the tool ( 11 ) and the tool ( 3 ) corresponding to the corresponding coordinate point (X, Y, Z, A) would lead to a collision or spatial intersection of the tool with the workpiece. This database (D) constitutes a look-up table, which can be used to check a given path or to extend a path or build it step-by-step. The calculation of the time-advantageous path can also be completed within a few seconds for a limited computing capacity, since the time- and computationally-intensive state calculation is omitted. It can be traced back to the precomputed viewing table.

Description

technical field [0001] The invention relates to a machine tool control for a grinding or similar machine tool and a method for determining the movement path of a tool, in particular a grinding tool, and / or a corresponding workpiece. Background technique [0002] In the case of grinding machines or similar machines, such as corrosion machines or similar equipment, it is often necessary to adjust the workpiece and / or the tool relative to each other without collisions. This is the case, for example, when a machining process with one grinding tool is terminated and another grinding tool acts on the workpiece. The control of the position of the workpiece and the grinding tool and the path to be run continuously is the content of the machine control program, which provides a more or less intelligent program assistance to a machine tool adjustment device or the operator. In this case, such program assistance usually does not allow the machine tool setting to produce a time-optimiz...
