Hydraulic　power　chuck　clamping　force　has　been　the　main　factor　of　the　precision　ultra-precision　machining　precision　of　modern　CNC　machine　tools.　To　solve　this　problem,　the　designed　wireless　sensor　system　can　achieve　the　real-time　detection　of　chuck　dynamic　clamping　force.　The　system　can　provide　on-site　real-time　monitoring　data　signals　and　wireless　data　transmission,　and　the　PC　can　accept　and　display　real-time　dynamic　monitoring　results　and　other　functions.　At　the　same　time,　the　system　has　a　temperature　error　compensation　function　to　ensure　a　more　accurate　function　curves　of　the　relationship　between　clamping　force　and　chuck　speed,　and　provides　important　theoretical　basis　in　improving　the　modern　CNC　machine　tools　spindle　speed　as　well　as　optimizing　design　of　hydraulic　cylinders　and　hydraulic　power.
