Method for forming a bevel cut at an end of a wood member

摘要

A method for forming a bevel cut at an end of a wood member is disclosed. A wood member is placed on a support table and a plurality of cutters mounted on and spaced along a shaft extending in parallel to the end of the wood member on the table is moved relative to the table in a direction inclined with respect to the wood member thereby to make a first cutting to form a plurality of bevel cuts. The support table is shifted in the direction parallel to the end of the wood member and a second cutting is made by the relative movement between the cutters and the table. During the first and second cutting, the wood member is pressed against the support table by a pressing member at a position adjacent to the end of the wood member and between any two adjacent cutters.

1. A method for forming bevel cuts at an end of a wood member, comprising steps of:
(a) placing a wood member having a straight end extending perpendicular to an infeed direction thereof on a support table, said support table having cutouts therein at an end thereof, the straight end of said wood member being located adjacent to the end of the support table; (b) pressing the wood member against the support table by pressing members at a position adjacent to the straight end of the wood member; (c) moving at least one of the support table and a plurality of cutters relative to each other in a perpendicular direction to the straight end of said wood member placed on the support table,
said plurality of cutters being rotatable about a common axis of rotation extending parallel to the straight end of the wood member placed on the support table andeach having a cutting width L1 as measured along the common axis,said cutters being spaced along the common axis with a spaced distance mL1 between any two adjacent cutters,where m represents an integer that is one or more,said step (c) occurring in an inclined direction with respect to opposite surfaces of the wood member placed on the support table,thereby allowing said cutters to perform a first cutting step to form an inclined end of the wood member at the straight end of the wood member,said first cutting step being performed with the wood member pressed against the support table by the pressing members at a position between at least any selected two adjacent cutters,said cutouts in the support table being inclined substantially in the same direction as a direction in which the cutters are allowed to move past the support table so that no interference occurs between the cutters and the support table during said movement; (d) releasing the pressing of the wood member by the pressing member; and (e) shifting at least one of the support table and the cutters to a shifted position relative to each other in a direction along said common axis of the cutters for a distance of nL1, where n represents an integer that is one or more; (f) moving at least one of the support table and the cutters relative to each other at said shifted position along said inclined end of the wood member formed after the first cutting step
thereby allowing said cutters to perform a second cutting step at the straight end of the wood member;said second cutting step being performed at least once after the first cutting step,whereby a series of continuous bevel cuts each extending from one surface of the wood member facing towards the cutters to the opposite surface of the wood member are formed at the straight end of the wood member at an interval of L1,said series of continuous bevel cuts each having a width of L1 along the straight end of the wood member, andtwo continuous surfaces inclined and forming a V-shape at any section across the bevel cuts at the straight end of the wood member at an interval of L1.
