Machining properties relate to the behavior of wood when planed, shaped, turned, or put through any other standard woodworking operation. Wood in general is easy to cut, shape, and fasten. For some purposes the difference between woods in machinability is negligible; for other uses, however, as in furniture and fixtures, the smoothness and facility with which woods can be worked may be the most important of all properties. Unless a wood machines fairly well and with moderate ease, it is not economically suitable for such uses regardless of its other virtues. Thus, along with specific gravity and tendency to split and warp, machinability is of first importance to the woodworker.
