Disclosed is a method and apparatus for machining a workpiece (2). The method comprises specifying a path along which a cutting tool (6) is moved during machining the workpiece (2), the path comprising segments (26); defining, for each segment (26), an exit point on that segment (26); defining, for each segment (26), an exit path (38) from the exit point of that segment (26) to a point remote from the workpiece (2); performing a machining process including moving the cutting tool (6) along the tool path and machining the workpiece (2); and, during the machining process, when one or more criteria are satisfied: interrupting the machining process and, without machining the workpiece (2), moving the cutting tool (6) to the exit point of the current segment (26) and then along the exit path (38) of the current segment (26). |

1. A method of machining a workpiece (2), the method comprising:
specifying a tool path for a cutting tool (6), the tool path being a path along which a cutting tool (6) is to be moved during machining, by the cutting tool (6), of the workpiece (2), wherein the tool path comprises a plurality of tool path segments (26, 28, 30); defining, for each tool path segment (26, 28, 30), an exit point, wherein the exit point of a tool path segment (26, 28, 30) is a point on that tool path segment (26, 28, 30); defining, for each tool path segment (26, 28, 30), an exit path (38, 40, 42), wherein the exit path (38, 40, 42) of a tool path segment (26, 28, 30) is a path for the cutting tool (6) from the exit point of that tool path segment (26, 28, 30) to a point that is remote from the workpiece (2); performing a machining process including moving the cutting tool (6) along at least part of the tool path and machining, by the cutting tool (6), the workpiece (2); and, during the machining process, responsive to determining that one or more criteria are satisfied: interrupting the machining process and moving the cutting tool (6) along a current tool path segment (26, 28, 30) without machining the workpiece (2), from a current location of the cutting tool (6) to the exit point of the current tool path segment (26, 28, 30); and moving the cutting tool (6) along the exit path (38, 40, 42) of the current tool path segment (26, 28, 30). |
