METHOD FOR MACHINING WORKPIECES WITHIN A MACHINING MACHINE

Abstract

In a method for machining workpieces within a machining machine a tool is moved relative to a workpiece (1). The tool or the workpiece (1) travels at a predeterminable travel speed in a travel direction which is predetermined by a movement path (3). The movement path (3) is divided into machining portions (4) and acceleration portions (5). Within the machining portions (4), the workpiece is machined between a starting point (6) and an end point (7) of the machining portion (4) at a predeterminable machining travel speed in a machining travel direction. The travel speed is adjusted along the acceleration portion (5), which is defined by the end point (7) of a first machining portion (11) and the starting point (6) of a second machining portion (12), such that the predetermined machining travel speed is reached at the starting point (6) of the machining portion (4).

Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0029] FIG. 1 shows a schematic representation of a predetermined movement path on a workpiece in a plan view of the workpiece, and

[0030] FIG. 2 shows a schematic representation of a movement path predetermined on the workpiece in a perspective view.

DETAILED DESCRIPTION

[0031] In FIG. 1, a workpiece 1 is shown in a schematic plan view. In addition, a movement path 3 is shown schematically on a workpiece surface 2 of the workpiece 1. A tool, which is not shown, is moved along the movement path 3 at a predeterminable travel speed in a travel direction predetermined by the movement path 3. The movement path 3 is divided into machining portions 4 and acceleration portions 5. The machining portions 4 are each defined by a starting point 6 and an end point 7, wherein workpiece machining is carried out in the machining portion 4 with the tool (not shown) at a machining travel speed. Along the acceleration portion 5 defined by the end point 7 of a first machining portion 8 and the starting point 6 of a second machining portion 9, the travel speed is adjusted so that the predetermined machining travel speed is reached at the starting point 6 of the machining portion 4. A first acceleration portion 11 is semi-circular in shape. A second acceleration portion 12 is divided into two acceleration path portions 10. The first acceleration path portion 10 is designed as a circular segment and the second acceleration path portion 10 is designed as a straight line. The second acceleration path portion 10, which precedes the starting point 6 of a third machining portion 13 in the direction of travel, is arranged without offset and without interruption to the third machining portion 13 in the direction of travel, so that the tool (not shown) is moved from the acceleration path portion 10 of the second acceleration portion 12 into the third machining portion 13 without abrupt travel movements.

[0032] In FIG. 2, the workpiece 1 is shown schematically in a perspective view. In addition, the movement path 3 shown schematically on the workpiece surfaces 2 of the workpiece 1 is shown. The tool, which is not shown, is moved along the movement path 3 at the predeterminable travel speed in the travel direction predetermined by the movement path 3. The movement path 3 shown in FIG. 2 is divided into the first machining portion 8, a second machining portion 9 and acceleration portions 5. The acceleration portion 5 is divided into two acceleration path portions 10. The second acceleration path portion 10 is arranged in an acceleration path plane that differs from a machining path plane comprising the starting point or the end point of the machining portion.

[0033] In the illustrations in FIG. 1 and FIG. 2, only individual elements of several similar elements are labelled with a reference sign by way of example.
