RESEARCH ON CUTTING FORCE MODELLING AND INFLUENCE FACTORS FOR END MILLS WITH VARIABLE-HELIX ANGLE by JIN Gang, LI Hua, HAN JianXin, LI Dong, QI HouJun

“…Variable helix cutter can reduce the location error of the finished surface,leading to a more accurate machining operation.Considering the geometries of variable pitch and helix angle,and the piecewise continuous regions of the cutting,an analytical model for predicting the cutting force for milling process with variable helix angle cutter is presented.The validation of the proposed model is conducted via some cutting tests.Based on proposed model,the influence of variable helix character on cutting force is studied.Analyses show that cutting force coefficients obtained from the traditional cutting tool could be used to accurately predict the cutting forces of the variable helix cutting tool.The bigger helix angle corresponds to the smaller cutting force and bigger width of phase.The character of variable-helix angle has more significant influence on cutting force when axial depth of cut is larger.…”

Auto-collimation diffraction of two-dimensional metal–dielectric grating with azimuth angle of 45° by Wang Yi-Han, Wang Jin, Chen Yu-Da, Huang Zhi-Sen, Jia Wei, Zhou Chang-He

“…In this paper, we proposed, for the first time, a reflective two-dimensional metal-dielectric grating of which the (−1, −1) order beam is diffracted back along the input light direction, when the incident azimuth angle is 45°. With optimized structure, the (−1, −1) order diffraction efficiencies of transverse electric polarization (TE) and transverse magnetic polarization (TM) are 95.01 % and 95.04 % at incident wavelength of 632 nm, respectively. …”

Design Method of Crank-rocker Mechanism based on Maximum Value of Minimum Transmission Angle by Chen Haiwen, Wang Zhong, Zhao Fei

“…Under the conditions of giving the length of the rocker CD,swinging angle φ and advance-to return-time ratio K（extreme position angle θ）,in order to design crank-rocker mechanism with the maximum value of minimum transmission angle γmin,the supplementary angle β（be used to determine the position angle of the rotation center A of crank） is introduced,the function relation of minimum transmission angle γminand the supplementary angle β is established.Then the maximum value of minimum transmission angle γmincan be obtained by utilizing procedure of Matlab.At the same time,in view of the different K value,the mechanism of type selection is classified.Then,points out the typeⅠ and Ⅱmechanism can be used to design and typeⅠ mechanism is better in force-passing property when K ∈（1,3）.When K∈[3,+ ∞),if type Ⅱ mechanism is used to carry on the design,which will not be able to meet the requirement of the rocker swinging angle,if typeⅠ mechanism is used,which has low efficiency and is not conductive to transmission of the mechanism.…”
