It was showed that it is not necessary to use fixture at the early stage of machining , hut appropriate admittance must he set aside 结果表明，在粗加工阶段，可以不采用工装，但必须留出合适的加工余量，余量的多少可以通过节点最大位移来估算。
By programs , diamond circular blade is used to process the surface of irregular shape stones , including straight and curved states , various embossments 可通过自行编制的程序，实现石材表面的数控加工，粗加工无需靠模板，精加工无需成型模轮。
The heterogenite is partly treated in furnaces either in dr congo or in neighbouring zambia and then exported mostly to china via south african and tanzanian ports 水钴矿在刚果金或者邻国赞比亚入炉进行粗加工然后大部分经南非和坦桑尼亚的港口出口到中国。
Considering the die - cavity roughing being a 2 . 5d cutting , a novel cutting force surface model is created based on orthogonal cutting tests 鉴于模具型腔粗加工常采用2 . 5维加工，提出一种通过正交切削试验建立切削力曲面模型用于模具型腔粗加工进给率优选的新策略。
Notice : the dimensions shown on the attached dwgs for ball are the finished ( after final machining ) dimensions ; your rough machined forging must guarantee these final dimensions 注：附件球体图纸上的尺寸为机加工后的最终尺寸，你们的粗加工锻件必须保证这些最终尺寸。
Aimed at two shortages during rough working procedures - cast blanks with large - scale free form surfaces are distorted significantly and cutting stocks are distributed very dispersely , a new hogging algorithm is proposed 摘要提出了一种新的毛坯荒加工算法，解决了在粗加工时大型复杂曲面毛坯变形严重、馀量分布不均匀等问题。
Food industry production from the procurement of raw materials to food storage and acceptance , recipients , rough machining , cutting into sales with cooking , the whole process of business links , a part of any errors will affect the quality of products 餐饮业的生产从食品原料的采购到验收储存、领用、粗加工、切配烹调到销售，整个过程业务环节多，任何一个环节出现差错都会影响产品质量。
Then , the processed data is directly turned into 2 . 5 - axis contour milling nc codes after analyzing the format of iso nc code and choosing some important parameters . the 2 . 5 - axis contour milling tool path is simulated in the mastercam software 然后,在分析了isonc代码的格式后,选取适当的工艺参数,将处理后的边界点数据直接转换生成2 . 5轴层轮廓粗加工nc代码,并在mastercam软件中仿真验证结果。
You are therefore requested to send us your most competitive offerreturn fax / e - mail indicating clearly the tech . specifications , detailed item costing ( raw casting or m / c casting as applicable ) , pattern cost & other terms & conditions within 07 days of receipt of this enquiry 因此你需要给我们最有竞争力的报价，并在收到该询价确认后7日内，以传真或者邮件回传明确说明该项技术，规格详述，详细的成本条款（粗加工或者按要求加工） ，图案的价格及其他条款及条件。
Firstly , tool - path for rough machining is generated through setting cutting depth , machining allowance and other parameters . interferences are resolved through raising the z - components of the generated cl point according different kind of situations . and then two methods to generate tool - path for finish machining is presented 首先通过设定切削深度和加工余量等参数生成递归分割曲面模型的粗加工刀具轨迹,对刀具轨迹生成过程中多种抬刀情况分别进行处理,避免粗加工中的过切干涉。
