The approach includes ( 1 ) obtaining the cutter - location data based on parameter curves . ( 2 ) tessellation of the trim nurbs surfaces into triangles . ( 3 ) interference detection and tool - position correction 在曲面的参数线上规划刀位轨迹，将曲面用三角片离散逼近，利用刀具曲面与三角片的几何相关性进行干涉检查及刀位修正。
Then , a machining simulation of face is completed with the numerical control machining module in ug and the cutter locus files with machining parameters and processing technical requests are generated 其次,应用ug软件的数控加工模块完成了对人脸曲面的加工仿真,并结合机床的参数设置和加工工艺要求得到了刀轨路径文件。
Machining experiments are finished on a mini precision machining cutter , in the process the nc codes can be used and the cutter radius compensation algorithm of five - axis linked nc machining cutter is turned to be correct 在小型精密数控机床上进行了加工实验,验证数控代码的可行性及五轴联动数控机床刀具补偿算法的正确性
Remark : this type of tapes utilize bioriented polypropylene ( bopp ) as the backing material with acrylic adhesive . the are light transparent , with a thin adhesive coating . the cutters are offered with the tpaes 备注：文具胶带是以聚乙烯薄膜（ bopp ）为基材，涂以丙烯酸脂压敏胶制造而成，具有薄而透明的优点，并配备胶粘带切割器出售。
The main fram is designed . every mechanism " s location and how to joint them are analysised . ( 2 ) by analysis of the working principium and process of the roadheader , the cutter " s driving forces are investigation ( 2 )通过对掘进机工作原理和作业过程分析，研究在截割作业时截割头的受力情况，为确定工作机构受力提供依据。
The moulding process of the cutter has been accomplished by fitting the geometric elements together in the opposite direction of function decomposition , which greatly improve the efficiency and quality of the design 然后按照功能分解的反方向对各几何体素进行拼合完成刀具的造型过程，从而大大提高了成形刀具的设计效率和设计质量。
First , format of the cutter location file in the nc system of bonnet toolpolishing is studied which provides useful information for postprocessing , including both process parameters in the process of polish and cutter path 首先，本文研究并制定了刀位文件的格式，该文件为后置处理提供加工过程中的工艺参数信息以及加工路径信息。
We must first clear of the old line , when constructed line , motor drive the cutter made of hard metal alloy to revolve at high speed , then erase old line 在有残损热熔标线的路面进行划线施工时应首先用清除机将旧标线清除干净。该机使用发动机带动硬质合金制成的打磨头高速旋转，打磨头在旋转离心的作用下与路面凸起部分磨合，将旧线清除。
