A method for controlling the feeding amount of a horizontal band saw blade comprising the steps of:
- detecting changes in the wear of the band saw blade during a cutting operation;
- and
- controlling the feeding amount of the band saw blade in accordance with the detected changes in the wear of the band saw blade.
A method for controlling the feeding amount of a horizontal band saw blade comprising the steps of:
- detecting a change in the transversal and normal components of the band saw blade which correspond to wear of the blade;
- and
- controlling the feeding amount of the band saw blade in accordance with variations in the wear of the band saw blade defined by changes in the detected transversal and normal components.
An apparatus for controlling the feeding amount of a horizontal band saw blade so as to obtain a constant optimum cutting rate, said apparatus comprising:
- detecting means for detecting a change in the amount of transversal and normal components of the band saw blade which correspond to the abrasion of the blade;
- a computing process unit for generating signals defining the amount of the desirable cutting resistance from said detected transversal and normal components and a constant optimum cutting rate;
- and
- pressure controlling means for controlling the cutting resistance in response to said signals generated by said computing process unit.
An apparatus for controlling the feeding amount of a horizontal band saw blade so as to obtain a constant optimum cutting rate, and said apparatus comprising:
- first means for detecting the amount of the wear of said band saw blade;
- second means for detecting the amount of cutting resistance;
- a computing process unit for generating signals corresponding to the amount of the desirable cutting resistance from said amount of wear detected, said amount of cutting resistance detected and a constant optimum cutting rate;
- and
- pressure controlling means to control the cutting resistance in response to said signals generated by said computer process unit.
