Embodiment Construction

[0034] figure 1 A saw table 1 of a band saw machine is schematically shown, on which a workpiece 2 (here a cylindrical strip) is placed. Above the workpiece, the saw band 3 as a saw blade circulates around two deflection rollers (not shown) in the upper part of an elevating saw machine. The saw band moves from right to left within the drawing in the selected view.

[0035] Such as figure 1 The moment shown is the start of the actual cutting process: the saw band 3 moves downwards during the feed movement in the cutting plane which coincides with the drawing plane in the selected view and moreover comes into contact with the workpiece 2 . In the joining section 4 , the saw band 3 cuts into the material of the workpiece 2 and cuts through the workpiece by the cutting action of the saw teeth arranged on the lower end of the saw band 3 .

[0036] figure 2 A later moment in the cutting process is shown. Here, the saw band 3 is located approximately in the center of the cross-...

Abstract

A method for controlling a sawing machine is provided. For a first cut in a workpiece, a working feed rate that is specific to the workpiece geometry, the workpiece material and the sawing tool is defined in advance. During the first cut, an instantaneous value of a physical variable is determined at a frequency converter, that is related to the torque transmitted by the sawing tool drive to the sawing tool, and this value is transmitted as an instantaneous torque value to a machine controller. The instantaneous torque value is continuously evaluated, a maximum torque value of the first cut is determined and a maximum value for the torque value is defined based thereon. For subsequent cuts in the same workpiece, the working feed rate is regulated, using the instantaneous torque value as a regulating variable, such that the instantaneous torque value is kept constant, close to the maximum valve.

Description

technical field [0001] The invention relates to a saw machine control method according to the preamble of claim 1 and a saw machine according to the preamble of claim 10 . Such a saw machine is also used in the method and includes a saw blade, which is driven by an electric saw blade drive with a frequency converter. In addition, a saw feed device is provided which moves the saw blade relative to the workpiece to be sawed at a variable feed speed by means of an electric feed drive. Finally, the saw machine also includes a machine control. Background technique [0002] Saws of this type are usually constructed in the form of band saws or circular saws, occasionally also in the form of hacksaws. The main field of application of the invention is the cutting or sawing of metal workpieces. [0003] Depending on the type of saw machine, the driven saw blade (ie generally the saw band or circular saw blade) is moved relative to the workpiece linearly or about a rotary axis. The...
