The material of the spare part is HT20-40.
The value of the dimension difference � D depends on many factors such as the material and diameter of the nylon bar, abrasive particle size, the dimension and surface quality of the processed hole and the dimension of the burr.
Journal Title and Volume Number (to be inserted by the publisher) 129 The choice of the abrasive particle size also depends on the surface roughness of the hole and the precision accuracy of the surface quality that the work piece must have.

Research on warehouse safety warning system based on multi-sensor fusion Liang Hou 1, a, Guangyu Li 1,b 1 School of Information Engineering Jilin Agricultural Science And Technology College Jilin, China aHou_Liang1@126.com, bLi_Guangyu1@125.com Keywords: wireless communications; temperature monitoring; smoke detector; infrared monitoring.
The results show that the use of security warning systems can use the limited funds to address storage warehouse security risks in the complex security environment, improve the efficiency of storage and security management of funds, save manpower, material and financial resources, and reduce storage costs.
On the basis of comparative analysis of modern security technology, this paper comprehensively utilized computer vision technology [2], sensor technology (temperature, smoke, infrared sensing), wireless communication technology, RFID radio frequency technology [3], database management technology and other advanced technologies, proposed storage security early warning systems framework based on multi-sensor fusion and developed online storage security monitoring and early warning system, achieving the reservoir area of the range of fire, theft monitoring and timely transmitting the warehouse exception information to the monitoring person over wireless networks to ensure the safe of storage materials.
It saves manpower, material and financial resources, and reduces storage costs.The research of safety warning platform can meet security warning problem by warning eliminate security risks, it tries to eliminate the danger in the bud to reduce disaster losses the maximum extent under current conditions.
