但是五軸聯(lián)動數(shù)控機(jī)床系統(tǒng)價(jià)格十分昂貴，加之在數(shù)控程序編制上存在著很大困難，因而如何使得五軸加工得以“平民”化應(yīng)用，已經(jīng)成為機(jī)床制造業(yè)的一個(gè)熱點(diǎn)問題。本文從虛擬機(jī)床技術(shù)開發(fā)，探討其在五軸加工的應(yīng)用，實(shí)現(xiàn)仿真加工，優(yōu)化數(shù)控程序，從而提升加工質(zhì)量、提高加工效率、降低加工成本。
2、虛擬機(jī)床應(yīng)用的優(yōu)勢
數(shù)控加工最終的好壞取決于以下5個(gè)因數(shù)中的短板：數(shù)控機(jī)床、控制器、刀具、數(shù)控編程和CAM軟件。虛擬機(jī)床的應(yīng)用正好可以解決以上短板問題，采用虛擬機(jī)床存在以下優(yōu)點(diǎn)：
2.1 真實(shí)性
傳統(tǒng)CAM軟件驅(qū)動的標(biāo)準(zhǔn)模擬仿真是一種不完整的近似運(yùn)動模擬，不能避免實(shí)際加工過程中的過切與撞刀。虛擬機(jī)床技術(shù)采用內(nèi)置CNC控制器驅(qū)動的加工模擬仿真是真實(shí)可靠的，可以把加工中的各種風(fēng)險(xiǎn)（撞刀、過切等）降為零。
2.2 先進(jìn)性
虛擬機(jī)床不僅可以仿真?zhèn)鹘y(tǒng)的車床、銑床、加工中心，而且可以仿真車銑復(fù)合和多軸聯(lián)動機(jī)床。目前，西門子公司的虛擬機(jī)床對于不同CNC控制系統(tǒng)的特殊加工指令及FMS柔性制造系統(tǒng)可以進(jìn)行仿真。
2.3 互操作性
虛擬機(jī)床不僅提供三維數(shù)字機(jī)床，而且包含虛擬控制面板，提供和車間環(huán)境一樣的虛擬實(shí)訓(xùn)環(huán)境。應(yīng)用虛擬機(jī)床，可以實(shí)現(xiàn)學(xué)生的大量仿真與真實(shí)機(jī)床沒有區(qū)別。這對于目前企業(yè)緊缺的中高端數(shù)控人才，是一個(gè)很好的培訓(xùn)解決方案，使復(fù)雜機(jī)床的編程及加工操作培訓(xùn)費(fèi)用降低50%，從且可以大大地降低培訓(xùn)成本。
