11、SLIDE, SETUP, PART, BLANK, AND FIXTURE注意：在運動關系結(jié)構(gòu)樹中，Y-SLIDE是Z-SLIDE的兒子， X-SLIDE是Y-SLIDE的兒子，這是因為當saddle移動時，y-cross隨之而動，同樣當y-cross移動時，x-table也隨之而動。另外，SET_UP, PART, BLANK, FIXTURE可以不包含幾何 26Based on your machine manual注意：對本實例，將所有的運動相對于一個坐標系統(tǒng)(MACHINE_BASEMACHINE_ZERO)進行定義已經(jīng)足夠 。在其它復雜結(jié)構(gòu)中，可能需要定義其它的Junctions.
