A method for controlling a wall saw system during creation of a separating cut in a workpiece. The wall saw system includes a saw head, a pivotable saw arm, a first saw blade, and a larger second saw blade. The separating cut is performed in a plurality of main cuts, where the parameters of the main cuts (saw blade diameter of the saw blade used, main-cut angle) are defined before the start in a main-cut sequence. After the processing of the separating cut by the first saw blade is concluded, the controlled processing of the separating cut is interrupted by a control unit and the wall saw is moved into a parking position such that all actions of the saw-blade change (swinging out the saw arm, removing the first saw blade, installing the second saw blade, and swinging in the saw arm) can be performed.

Method for controlling a wall saw system during the creation of a separation cut

A method for controlling a wall saw system during creation of a separation cut in a workpiece between a first and second end point, is disclosed. The separation cut is carried out in a plurality of main cuts. In addition to the main-cut sequence, an overcut sequence having at least two overcuts is defined for each end point defined as a free end point. For each overcut sequence, a starting position and an end position are defined, the overcuts being carried out therebetween. The wall saw is positioned in the starting position and is pivoted into a first overcut angle; subsequently, the saw head is moved by way of the inclined saw arm until the end position has been reached. The wall saw is displaced back into the starting position and pivoted into a second overcut angle. This sequence is repeated until all of the overcuts have been carried out.

Method for controlling a wall saw system when making a separating cut

A method for controlling a wall saw system during the creation of a separating cut in a workpiece. The movement of the saw head is controlled at the end points such that a boundary of the wall saw facing the end point coincides with the end point after the pivoting movement of the saw arm. In the case of a free end point, the boundary of the wall saw is formed by an upper exit point of the saw blade. In the case of an obstacle, the boundary of the wall saw is formed by the saw blade edge of the saw blade if the processing occurs without the blade guard or by the blade guard edge of the blade guard if the processing occurs with the blade guard.

A method for controlling a wall system when creating a separating cut in a workpiece between a first and a second end point is disclosed. The wall saw system includes a wall saw having a saw head, a pivotable saw arm, a saw blade and a blade guard. The separating cut is carried out in a plurality of main cuts. The pivoting movement of the saw arm in a main cutting angle is carried out in at least two steps with at least one intermediate angle, where a free cut of the saw blade is carried out in the respective intermediate angle between the pivoting movements of the saw arm.
