Abstract
A crude curved log with an essentially circular cross-section is before a first machining cycle in a working machine fixed in a rotary condition where the longitudinal sectional plane comprising the maximum curvature is horizontal, and is then measured and processed along curved paths determined in a computer unit on the basis of the measured curvature. Thereafter the central block, thus obtained is processed, in a second cycle along paths having the same curvature as the first cycle by utilizing the same command signals as in the first cycle are used, possibly with a correction for changed lateral position of the block.
