The quality yield capability of a sawing process is defined by three factors:
Reproducibility of a sawing machine may be assessed only in the long term.
The extensive data reveal a comprehensive view of the process mean, the standard deviation with [+ or -] 2 limits, and their variation at different points of the sawing process (far right graph in Fig.
The following discussion will concern only the total standard deviation and reproducibility of a sawing process, because the accuracy of a saw depends only on the correct position of the saw-blades in a set-up.
The stresses that cause sawing variation in a saw machine depend on multiple factors, the most important of which are the volume of removed wood in a cut and sawblade wear.

Used only on large, very rigid sawing machines for high-production sawing of difficult materials.
After the material to be cut has been properly identified, the selector on the machine can be used to help select the proper blade and cutting speed, tables and selectors are helpful, but the operator often must make choices that affect the three variables present in every sawing operation: cutting rate, tool life and accuracy.
In most sawing operations, the work is held stationary and the saw blade is moved relative to it.
This method of sawing is often used in cut-off operations.
Other specialized series of saw blades available include glue-joint ripping, rip-to-mould, splitting mouldings or slats, grooving, production of MDF door cores and moulding blanks and sawing acrylics.
The Model MR-21 panel ripsaw from Multiscore reportedly minimizes cutting labor by single-pass ripping an entire panel, including narrow strips, and does simulataneous sawing and grooving.
