Turning the Auxiliary Force Measurement System Design
Abstract:The main content of this paper is to design a new type of turning dynamometer. There is a direct relationship between measurement design standard dynamometer and turning force. The cutting force generated during metal cutting have a direct influence on thegenerafion of cutting heat，tool wear,and quality of machined surface，and accuracy of theworkpiece．Duo to the complex cutting conditions of metal cutting operation and some unknown factors，theoretical cutting force calculations fail to produce accurate results．Therefore，experimental measurements of cutting force become unavoidable．For this purpose，many dynamometers have be developed，most of which concentrated on smile eutilng force．Now there is need to put great emphasis on the dynamic component of cutting force to satisfyhigh machining accuracy．The distributed dynamometer is made up of bit tool，force sensor，toolbar and screws．The middle SCreW which goes through quartz plates is used to constrain thermal deformationand compensate the decreasing preload caused by culling heat based on ANSYS simulationand theoretical analysis．It is proved that this structure canreduce the influence of cutting heatin some degree by cutting test，but Can not meet the demand．The unitary dynamometer has a‘'push-puU”structure，which Call improve the sensitivityand compensate the errors caused by cutting heat automatically．This structure essentiallycontains an important elastic ring element,which must produce defonnation proportional toexternal load and has high rigidity
