设计完微型工具机后，接著探讨最佳的切削参数，本论文采用瞬时投影面积的数学模型，且推导出利用刀具半径、主轴转速、径向切深、进给速度等参数来做为瞬时切削投影面积的函数，并使用软体mathematica算出瞬间面积大小，预测出切削过程里所产生的切线切削力、径向切削力和轴向切削力。

Here we present a case of 21 year-old male who suffered from recurrent swelling in left side of mandible which had received surgery for ossifying fibroma in another hospital when he was 19 years old. Obvious facial asymmetry was noted but no sensory dysfunctions were detected. The lesion showed well-demarcated, multilocular radiolucency but radiopacity centrally. We applied segmental resection via extra-oral approach and reconstructed with anterior iliac crest bone graft. After removal of MMF in six week, the wound healed well and joint function was good without malocclusion. After follow-up of one year, no recurrences were noted.

本病例为－21岁之男性，在19岁时因为左下颚骨角区肿大在某医院接受外科手术处理，术后病理报告为骨化纤维瘤，因为复发的肿胀而来本院寻求治疗，临床检查并无疼痛及下唇区感觉异常的问题，放射线影像为周界清晰，多腔室放射透过性合并中央放射不透过性之不规则小块，手术方式为从口外颚下切线，做下颚骨片段式切除，并以肠骨脊海绵骨移植修补骨缺损加以颚间固定六周，术后伤口恢复及愈合良好，颚骨关系稳定无咬合异常的情况，无张口受限的问题。

The degree of separation between the posterior dural sac and its subjacent lamina was ealuated within a range defined medially by the point of junction with the lamina and laterally by a tangential line along the medial aspect of the pedicle.
