The trepanning cutter provided by the utility model has better machining linearity and coaxiality, higher machining precision and efficiency, capability of effectively ensuring the smoothness of an inner hole, and longer service life.

The invention belongs to the field of forest quality evaluation, and discloses a forest quality comprehensive index evaluation method and system, and the method comprises the steps: S1, carrying out the photographing of a to-be-evaluated forest through employing an improved aerial photographing scheme, and obtaining a plurality of aerial photographing images; s2, obtaining a spliced image based on the plurality of aerial images; s3, calculating the vegetation coverage rate of the forest to be evaluated based on the spliced image; and S4, calculating a comprehensive evaluation index of the forest to be evaluated based on the vegetation coverage rate. According to the air route planning mode, the situation that an over-small interval between air routes is set in an area with the high altitude change rate can be avoided, and the number of the air routes can be effectively reduced. Besides, shooting is carried out on the same route by using a self-adaptive shooting interval, so that the number of aerial images in an area with a relatively high altitude change rate is increased, and the effectiveness of a spliced image obtained by splicing the aerial images obtained by shooting can be kept.

The present invention belongs to the field of shipboard cabin installation, and specifically relates to a method for installing and positioning a shipboard B-type cabin using a three-dimensional adjustment machine. The method comprises the following steps: arranging the position of a three-dimensional adjustment machine (15) in a hull (2) and installing it; using a lifting device to vertically lift the B-type cabin (1) into the hull (2); lifting and hovering for the first time, adjusting the transverse position and longitudinal position of the B-type cabin (1); the lifting device continues to vertically lift the B-type cabin (1) into the hull (2); lifting and hovering for the second time, adjusting the transverse position and longitudinal position of the B-type cabin (1) again; after the lifting device continues to lift the B-type cabin (1) to the installation position, the B-type cabin (1) is installed by operating the three-dimensional adjustment machine (15); and finally, the three-dimensional adjustment machine (15) is moved out of the hull. The method of the present invention is simple, efficient and accurate, and reduces production costs.
