The ways upgrading contour bandsaws by using aerostatic bearings are discussed.

Saw-guide is a device used to guide sawblade in bandsaws.

Development of the numerical control woodworking curve band saw;

Study again on the band saw relation between straining lever position and tensile force

According to the characteristic of the band saw machining,a fuzzy control method was introduced into the feed device of band, and a fuzzy control ruler was designed,the test show that the fuzzy control technology can improve the machining quality and optimize the machining process.

Based on the study of the woodworking band saw machine's process characteristics,the natural frequencies of the worktable and the structural system of saw blade and the lateral swing quantity of saw blade by cutting the China fir under the same condition were tested under the condition of the constant tension force of the saw blade and feed speed of MJ397 high speed woodwork band saw machine.

A improving level and weight model tensile system for band saw machine was devised on existing level and weight tensile,compared to existing mechanism in band saw vibration.

In order to solve the problem of saw blade departure, increase the rate of lumber yield, this paper designs a feedback control system for the band saw machine feed-in set, base on the computer control, according to the lateral displacement of the saw blade, the system autocontrols the federate.
