Abstract
In order to obtain a desired course of a machining line differing from a straight line or a corresponding flank line of a workpiece profile, it is necessary to control the working point of the tool 2 so that on the rectilinear stroke movement of the tool 2, a movement extending transversely thereto is effected by a tool positioning device 4. Such a device is constructed in the form of a toggle mechanism on which further fine control movements can be imposed through a series of adjustment possibilities.
Claims36
A device for controlling the tool position including the extent of lift of the tool relative to a work table and also at least one of a lifting direction of the tool relative to a work table and a course of the machining line of the tool along the length of the stroke of the tool, depending on the stroke position on machine tools with a reciprocating tool movement, such as shaping or slotting machines or planers, wherein a workpiece is received by a work table and a tool (2) is received by a tool head (1) and one of the work table and the tool head is connected to a tool positioning device for controlling the relative position between tool (2) and workpiece in the sense of a tool positioning relative to the stroke position, characterised in that the tool positioning device (4) comprises a control mechanism, connected to at least one drive device, to adjust the extent of lift and also at least one of the lifting direction, and the course of the machining line.
