Through the processing simulation, NC machining simulation can simulate the overall process of NC machining intuitively in computer without using physical materials and occupying machine, also it can inspect the rationality and exactness of NC code, thus it plays a role of shortening product developing cycle, reducing the cost of product and improving utilization ratio of machine [3] [4].
This paper adopted three axis Siemens NC mill machine as the processing machine, selected ABS resin as blank material.

Since their treatment require thorough excisions, bone substitutes have been studied for restoring bone continuity, but with limited efficacy due to the pathophysiology of bone infections; one of the classes which proved to be efficient were the BioActive Glasses [BAG], synthetic biocompatible inorganic materials with a controlled ionic release, with demonstrated properties of wound healing, osteoconduction, angiogenesis and antibacterial activity.
This paper presents the clinical experience from a Level 1 Trauma Centre where post-traumatic osteitis was treated using BioActive Glasses as bone fillers, demonstrating the potential clinical impact of these materials.
Introduction BioActive Glasses [BAG] are synthetic biocompatible inorganic materials that bond to surrounding tissues, and, due to a controlled ionic release induce wound healing, osteoconduction and angiogenesis, also demonstrating antibacterial activity [1-3], which is particular interest for orthopaedic surgeons due to several characteristics of bone infections.
