Introduction

Withthedevelopmentofhydraulictechnologyandnumericalcontroltechnology,theintegrationofbothtechnologieshasbecomeatrendinthedevelopmentofhydraulicsystems.Hydraulicservosystem,withitsexcellentperformanceinenergysaving,speedregulation,andaccuracy,hasbeenwidelyusedinvariousindustriesandhasbecomeanimportantcomponentintheautomationindustry.Inthefieldofmachinetools,thenumericalcontrolsystemandhydraulicservosystemhavebeensuccessfullycombined,whichhasbroughtnewvitalitytothedevelopmentofmachinetools.

Inthispaper,thedesignandapplicationofhydraulicservosystemfornumericalcontrolarestudied,anditsapplicationinmachinetoolmodificationisdiscussed.Thepaperfirstintroducestheworkingprincipleandstructureofthenumericalcontrolhydraulicservosystem,andthenanalyzesanddesignsthemaincomponentsofthesystemindetail,includingservovalves,electro-hydraulicservocontrollers,hydrauliccylinders,etc.Then,thepaperintroducestheapplicationofthenumericalcontrolhydraulicservosysteminmachinetoolmodification,includingspindlemodification,cuttingforcecontrol,servocontroloffeedaxes,etc.Finally,preliminaryexperimentalvalidationisconducted,andtheresultsshowthattheuseofnumericalcontrolhydraulicservosystemcansignificantlyimprovetheperformanceofthemachinetool.
