Method for Controlling a Wall Saw System During the Creation of a Separation Cut

A method for controlling a wall saw system, wherein the wall saw system comprises a guide rail and a wall saw with a saw head, a motor-driven drive unit that moves the saw head parallel to a feed direction along the guide rail, a saw blade fastened on a saw arm of the saw head wherein the saw arm is pivotable about a pivot axis and around an axis of rotation, and a detachable blade guard surrounding the saw blade;

• and comprising the steps of:
• creating a separation cut of a final depth (T) in a workpiece of workpiece thickness (d) between a first end point (E1) and a second end point (E2), wherein at least one of the first and second end points is defined as a barrier, by the wall saw system;
• wherein, before a start of a processing controlled by a control unit of the wall saw at least a saw blade diameter of the saw blade, positions of the first and second end points in the feed direction, the final depth of the separation cut, and a main cutting sequence of m main cuts, wherein m≧2 between the first and second end points, are determined;
• wherein the main cutting sequence comprises a penultimate main cut with a penultimate main cutting angle (αm−1) of the saw arm and a penultimate diameter (Dm−1) of the saw blade, and a final main cut with a final main cutting angle (αm) of the saw arm and a final diameter (Dm) of the saw blade;
• wherein, during the processing controlled by the control unit, the penultimate main cut is done with the saw arm inclined at the penultimate main cutting angle (±αm−1), and the final main cut is done with the saw arm inclined at the final main cutting angle (±αm);
• and wherein, before the start of the processing controlled by the control unit, in addition to the main cutting sequence, a corner cutting sequence with corner cuts is determined, wherein the corner cutting sequence comprises at least a first corner cut at a first corner cutting angle (±φ1.1, ±φ2.1) of the saw arm and a first diameter (D1.1, D2.1) of the saw blade, and a second corner cut at a second corner cutting angle (±φ1.2±φ2.2) of the saw arm and a second diameter (D1.2, D2.2) of the saw blade.

A method for controlling a wall saw system, comprising the steps of:

• defining a main cutting sequence for making a main cut in a workpiece;
• defining a corner cutting sequence with corner cuts, wherein the corner cutting
• sequence comprises a first corner cut with a first corner cutting angle of a saw arm of a saw and a second corner cut at a second corner cutting angle of the saw arm of the saw;
• and
• cutting the workpiece by the saw with the main cutting sequence and the corner cutting sequence.
