FIELD: process engineering. ^ SUBSTANCE: sawing blades are grouped into several angle pairs. Then, optimum cutting list is worked out to determine required number of cutting passes. Computer is used to distribute said required sequence of sawing blade strokes in optimisation zone between several angle pairs of sawing blades. Simultaneous stepped sawing of log block in performed in compliance with afore determined sequence distributed between pairs of sawing blade strokes before each kerf and instructions. Machine comprises several electrically driven sawing blades, sawing blade lengthwise feed drive, that to transfer each sawing blade perpendicular to motion of sawing blade lengthwise feed drive mechanisms. ^ EFFECT: higher efficiency, reduced idle time. ^ 12 cl, 7 dwg |
