Abstract: Due to the quality of cinnamon was affected by residue of surface peel，in order to improve value of cinnamon，method of polishing surface peel with flower head was studied.An experimental platform was established by lathe of HM5-L3.The experimental data was collected，saved and processed in real time by the LABVIEW platform of data acquisition.The load and output voltage were linearly fitted by the least square method combined with MATLAB.The maximum relative error of fitting was 5.31%.The accuracy met measurement requirements.Therefore，feasibility of the method was verified by analyzing polishing data.The relation between feed and maximum load in the range of 3-5 mm was given，and maximum relative error was 1.98% when the diameter of cinnamon was 55-65 mm.
