Benefits of technology
This approach effectively reduces chatter oscillation and associated noise, enhancing cutting precision and accuracy by creating a node where oscillations cancel each other out, particularly when the frequency of pulses is optimized between 116 Hz and 135 Hz.
Problems solved by technology
In some cases, this oscillation develops into a chatter oscillation accompanying abnormal noises.
Nevertheless, configurations of a conventional type impose limitation on the restraining of the chatter oscillation which occurs due to the longitudinal oscillation.

Embodiment Construction
[0048]Descriptions will be provided below for embodiments of the present invention by use of the drawings. Components which play the same functions as those of the conventional type play are denoted by the same reference numerals, and the repeated descriptions will be omitted.
[0049]As shown in FIG. 2, the configuration shown in FIG. 2 includes forced oscillation imparting means which imparts to the band saw blade 13 a forced longitudinal oscillation so that the phase of the oscillation which occurs to the band saw blade 13 in a main-component-force direction (in its rotational direction, in its running direction) (that is, the oscillation which occurs to the band saw blade 13 in its rotational direction or in its running direction, and which is a longitudinal or compressional oscillation) near the driving wheel 29 is substantially inverted to the phase of the oscillation which occurs to the band saw blade 13 in a main-component-force direction near the driven wheel 31. In other word...

Abstract
In a cutting-off method, when a workpiece is to be cut off by use of an endless band saw blade suspended between a driving wheel and a driven wheel, the workpiece is cut off by imparting to the driving wheel a forced oscillation so that a phase of an oscillation of the driving wheel along its rotational direction is substantially inverted with respect to a phase of an oscillation of the driven wheel along its rotational direction. In addition, pulses can be applied to a driving motor for rotationally driving the driving wheel in order to cause the driving wheel to oscillate along its rotational direction.
Description
TECHNICAL FIELD[0001]The present invention relates to a method of cutting off a workpiece using a band saw machine including a band saw blade, and to a band saw machine used for the cutting-off method. More specifically, the present invention relates to a method of cutting off a workpiece while restraining a band saw blade from chattering, and to the band saw machine used for the cutting-off method.BACKGROUND ART[0002]Band saw machines include vertical band saw machines and horizontal band saw machines. In order to facilitate understanding, schematic descriptions will be provided for an overall configuration of a horizontal band saw machine as an example of the band saw machines. As conceptually and schematically shown in FIG. 1, a horizontal band saw machine 1 includes a base 3. A vise device 5 to which a workpiece W to be cut off can be fixed is mounted on this base 3. The vise device 5 has a configuration including: a fixed vise jaw 9A which is fixed to a vise head 7 for supporti...
