The paper made choice of a feeding pattern and optimally designed a feeding mechanism,which satisfied the need of the wood s feeding speed to test saw chain sutting performance for LQ-18 type test-bed.

This article made a stress analysis into the drive link for saw chain by means of finite element method.

Introduced saw chain depth setting and cutting top run-out and cutting top total run-out and side clearance of the cutting edge testing method by the centesimal graduation meter and the instrument microscope, and discussed the testing error.
