ABSTRACT:
An automatic planning machine for cutting a surface of a workpiece which includes: a base portion on which the workpiece is to be laid; a feeding device for feeding the workpiece; a rotatable cutter block arranged on one side of the base portion with a rotary shaft substantially in a vertical direction; and a reference base disposed vertically on the other side of the base portion; wherein an upper side of a workpiece feeding path between the reference base and the cutter block is opened. A height of the reference base is lower than that of the cutter block and a top surface of the reference base is held horizontally. The automatic planning machine may comprise an auxiliary reference base which is detachably mountable on a top surface or a side wall of the reference base. The planning machine may further comprise a planing reference base disposed on a side of the cutter block, wherein the feeding device includes rotatable roller members each of which has a rotary axis substantially in a vertical direction, and spring members for pressing the workpiece, and a pressing device disposed in the reference base facing the planing reference base, for generating selectively a pressure which is larger than a pressure of the spring members of the roller members and a pressure which is smaller than the pressure of the spring members of the roller members to press the workpiece.
