  济南beplay全站app安卓零件精加工工艺是指哪些? 接下来就由笔者来给大家详细介绍一下吧!
  Jinan mold parts finishing process refers to what? Next by the author to give you a detailed introduction!
  精密beplay全站app安卓加工在实际加工过程中发现,以往使用固定轴铣时,如选择了UG 默认的圆弧插补方式,输出的PTP文件容量会较大,尤其是选择45度精加工。在预读能力稍差的机床上,如果使用较高的进给速度,工件表面会产生深浅不一的吃刀现象,使表面光洁度大为下降。在反复的实验中我们找出了一种合适的解决方法,选用了UG 提供的另一种圆弧插补方式,这种方式处理完后的ptp文件大为减小,使得机床的预读负荷减轻,能够轻松的在较高的进给速度下保持非常高的光洁度和表面质量。
  In the actual machining process of precision mold, it is found that when fixed axis milling is used in the past, if the default arc interpolation mode of UG is selected, the output capacity of PTP file will be larger, especially 45 degree precision machining. In the machine tool with poor pre reading ability, if a higher feed speed is used, the workpiece surface will produce a phenomenon of cutting in different depths, which greatly reduces the surface finish. In the repeated experiments, we find a suitable solution, and choose another arc interpolation method provided by UG. After this way, the PTP file is greatly reduced, so that the pre reading load of the machine tool is reduced, and it can easily maintain the unusual high finish and surface quality at a higher feed speed.
  刀路中过多的空程移动也是 HSM 的一大忌讳,能在粗精密beplay全站app安卓加工中选择偏置路径可减少许多不必要的跳刀,通常比和平行加工路径为佳,大大节省了开粗时间,刀具保持了恒定的切削力也延长了使用寿命。丰富切入切出及连接方式极大限度的满足了高速加工的要求另外,还具有独特的区域过滤功能,对于没有切削力的牛鼻刀,UG 可以使用该功能过滤掉一些加工盲区的路径,并且提出警告,避免断刀事故发生。虽然UG CAD 利用强大的后参数化工具能将不需进行铣削加工的模型特征修改或简化,但无疑这一过滤选项带来效率的提高和加工的安全性。
  Too much space movement in the tool path is also a big taboo of HSM. Choosing offset path in rough and precision die machining can reduce many unnecessary tool skipping, which is usually better than parallel machining path, greatly saving the cutting time, maintaining constant cutting force and extending the service life of the tool. Rich cut in and cut out and connection methods greatly meet the requirements of high-speed machining. In addition, it also has a unique area filtering function. For the ox nose knife without center cutting force, UG can use this function to filter out some processing blind area paths, and put forward a warning to avoid cutting accident. Although UG CAD can modify or simplify the model features that do not need to be milled by using powerful post parametric tools, there is no doubt that this filtering option brings efficiency improvement and machining safety.

  高速精密beplay全站app安卓加工对机床性能,刀具夹持系统,刀具质量,被加工零件材料,及CAM 软件的要求非常之高,各个环节都需要优良品质才能完成加工。其中影响的当属CAM 软件。HSM 对 CAM 软件提出了极高的要求:全程自动防过切处理能力及自动刀柄干涉检查,丰富的符合高速加工要求的加工策略,具有高计算编程速度,强大的智能化操作。而UG 在上述要求的都有完美的诠释,加工软件日新月异,而 Unigraphics CAM 却始终舞 蹈于业界的顶端,这就是我们选择UG 的主要原因。
  The requirements of high-speed and precision die machining are very high for machine tool performance, tool clamping system, tool quality, processed parts materials, and CAM software. Each link needs good quality to complete the machining. CAM software is the most influential one. HSM puts forward very high requirements for CAM software: the whole process automatic anti over cutting processing ability and automatic tool handle interference inspection, rich processing strategies in line with the requirements of high-speed machining, high computing programming speed, powerful intelligent operation. UG has a perfect interpretation of the above requirements, and the processing software changes with each passing day, while Unigraphics cam always dances at the top of the industry, which is the main reason why we choose UG.
  beplay全站app安卓的成型需经过两道抛光工序,已很难保证外观塑胶件所需的棱角分明等要求。在现代beplay全站app安卓加工中,直接用高速CNC 机床铣出高质量的光洁表面,及尽量使用直径细小刀具作深腔或清角高速加工,减少电火花加工,高速低负荷下切削,比低速高负荷切削更快切除材料,减少热变形,提高beplay全站app安卓生产效率,已是大势所趋,可称之为机械加工行业的一次革命。传统的工艺一直将EDM 做为精密beplay全站app安卓加工的一道精加工工序。它的优势在于,加工前对电极的检测可较好控制被加工零件的尺寸精度,加工过程中不存在硬性的干涉,热分布小,表面光洁度优于普通CNC 机床的加工质量等。但其也有一些缺点,给精密beplay全站app安卓尤其是外观极为重要的塑胶模生产带来困难。粗精电极的加工及检测将花费较长的时间。
  The mold needs two polishing processes, so it is difficult to ensure the sharp edges and corners required for the appearance of plastic parts. In modern mold processing, high-speed CNC machine tool is used to mill high-quality smooth surface, and small diameter cutter is used as deep cavity or angle cleaning high-speed machining as far as possible, so as to reduce EDM, Cutting at high speed and low load, cutting materials faster than cutting at low speed and high load, reducing thermal deformation, and improving mold production efficiency are the general trend, which can be called a revolution in machining industry. Traditional technology has always regarded EDM as the last finishing process of precision mold processing. Its advantage is that the electrode detection before machining can better control the dimensional accuracy of the machined parts, there is no hard interference in the process of machining, the heat distribution is small, and the surface finish is better than the machining quality of general CNC machine tools. But it also has some disadvantages, which bring difficulties to the production of precision mold, especially the plastic mold with extremely important appearance. It will take a long time to process and test the coarse and fine electrodes.
