摘要: An improved carving blank and mandrel for mounting the blank in a carving machine enables accurate carving of prosthetic and orthotic positive shapes. The blanks are simple to mount and dismount and means are provided enabling a repeatable mounting position in one angular orientation only to be achieved. The blanks are firmly fixed in place on the mandrel during the carving operation, and they are simple and inexpensive to manufacture thus reducing manufacturing costs while achieving high shape accuracy.
