Abstract

A method for controlling a device system ( 10 ) during the cutting of a workpiece ( 18 ) along a cutting line ( 43 ) up to a first end point (E 1 ) using a saw head ( 12 ) that can be moved on a guide rail ( 11 ) along an advancing direction ( 26 ), whereby the saw head ( 12 ) is arranged on the guide rail ( 11 ) in a starting position (X 0 ), and a first partial length (L 1 ) extending from the starting position (X 0 ) to the first end point (E 1 ) of the cutting line ( 43 ) is entered.

First claim

What is claimed is:

1. A method for controlling a device system during the cutting of a workpiece along a cutting line between a first end point and a second end point using a saw head movable on a guide rail in a positive advancing direction and a negative advancing direction, the cutting line including a total length extending from the first end point to the second end point, the method comprising:
arranging the saw head on the guide rail in a starting position between the first end point and the second end point, the starting position separating the total length in a first partial length extending from the starting position to the first end point and in a second partial length extending from the starting position to the second end point;
before moving the saw head on the guide rail, entering in a remote control of the device system, a value of a distance of the first partial length and a direction of the first partial length, the direction of the first partial length being the positive advancing direction or the negative advancing direction;
before moving the saw head on the guide rail, calculating by a first control unit of the saw head or a second control unit of the remote control, based on the starting position, on the value of the distance of the first partial length and on the direction of the first partial length, the position of the first end point; and
moving, by an advancing motor, the saw head on the guide rail alternately in the positive advancing direction and the negative advancing direction between the calculated position of the first end point and the second end point.

2. The method as recited in claim 1 further comprising:
before moving the saw head on the guide rail, entering in the remote control of the device system, a value of the total length extending from the first end point to the second end point of the cutting line; and
before moving the saw head on the guide rail, calculating by the first control unit of the saw head or the second control unit of the remote control, based on the starting position, on the first partial length and on the total length, the position of the second end point.

3. The method as recited in claim 2 wherein the value of the distance of the first partial length, the direction of the first partial length and the value of the total length of the cutting line are entered by the operator via operating means into the remote control of the device system.

4. The method as recited in claim 1 further comprising:
before moving the saw head on the guide rail, entering in the remote control of the device system, a value of a distance of the second partial length and a direction of the second partial length, the direction of the second partial length being the positive advancing direction or the negative advancing direction: and
before moving the saw head on the guide rail, calculating, by the first control unit of the saw head or the second control unit of the remote control, based on the starting position, on the value of the distance of the second partial length and on the direction of the second partial length, the position of the second end point.

5. The method as recited in claim 4 wherein the value of the distance of the first partial length, the direction of the first partial length, the value of the distance of the second partial length and the direction of the second partial length are entered by the operator via operating means into the remote control of the device system.

6. The method as recited in claim 1 wherein the value of the distance of the first partial length and the direction of the first partial length, a value of a distance of the second partial length and a direction of the second partial length or a value of the total length of the cutting line are entered by the operator via operating means into the remote control of the device system.

7. The method as recited in claim 1 wherein the value of the distance of the first partial length and the direction of the first partial length, a value of a distance of the second partial length and a direction of the second partial length or a value of the total length of the cutting line are entered via a sensor system for a distance measurement into the remote control of the device system.

8. The method as recited in claim 7 wherein the value of the distance of the first partial length and the direction of the first partial length, the value of the distance of the second partial length and the direction of the second partial length or the value of the total length of the cutting line are transmitted by the sensor system to the remote control of the device system via a communication connection.
