METHODS OF DESIGNING MOLDS FOR MACHINING COST REDUCTION |
摘要 |
An orthopaedic knee cutting block prepared by a process comprising the steps of: creating a mold with a first core detail and a second core detail, each of the core details corresponding to a volume; filling the mold with a mixture of a binder and a metal; releasing a green part from the mold, the green part having a first void corresponding to the first core detail and a second void corresponding to the second core detail; removing the binder from the green part; heating the green part to create a sintered part; and machining the part by sawing a cutting slot such that the cutting slot overlaps with the first void and the second void. Alternatively, the orthopaedic knee cutting instrument may be made by a simple metal casting method. |
