The Research on Metal Milling about down Milling and Inverse Milling for Application Shimin Wang a, Dongquan Zhao b and Rongqi Deng c Zaozhuang Vocational College of Science & Technology, Tengzhou 277500, China awsms@163.com, bzdq701018@163.com, cdengrongqi@163.com Keywords: Down milling; inverse milling; cutter compensation instructions.
See milling workpiece materials and surface roughness choose way. processing soft materials, such as copper, had better use conventional milling, compared to climb milling finish will be much better.
Should try to adopt suitable milling, milling, especially for that difficult to machine materials adopt suitable milling not only can reduce the cutting deformation, lower cutting force and power consumption.
With G41 and G42 programming process can ensure the size tolerance, form tolerance and surface roughness requirements, but with G41 instruction programming processing parts surface roughness than with G42 instruction programming processing parts surface roughness is ideal, especially when the workpiece materials for alloy steel (20), programming with G42 command, conventional milling processing, some slight vibration of workpiece, serious when mild chew milling-tool phenomenon, must choose in advance when programmers in the programming using suitable milling and inverse milling, rather than isolated use milling-tool repairing around instruction in programming.

Experiment methods Experiment mainly explore the composition of the fly ash, slag, water reducer, conservation of different raw materials affect on such as concrete early-age work performance, early-age crack resistance.
According to the "People's Republic of China building materials industry standards JC / T 951-2005 cement mortar cracking performance test method [2], survey and evaluate the early-age crack resistance of concrete slurry.
Part of the cement replaced by fly ash [5], the total heat of hydration of cementitious materials and the basic hydration peak temperature decreases with increasing fly ash content

Introduction LY12-CZ aluminum alloy materials are widely used in aviation field.
During use, these materials are subjected to high alternating stresses and impacts that cause damage growth and, ultimately, structural failure.
Besides, it is also difficult to use this technique to detect cracks appear in nonconductive material structures [6].
One is the conductive sensing coating on the top, and the other is the isolated layer consisting of Al2O3 materials in the interconnect layer.
