德国汽车冲压模制造商为何唯独选择了WorkNC软件超过20年 - iCAx开思网

German toolmaker Riemann Gmbh has been using WORKNC automatic CAD-CAM since the 1980s. Founder, Klaus Riemann recalls, “At the time we had two or three CAD-CAM software demonstrations and WORKNC was the only software that impressed us. We could easily select a wide range of milling strategies and automatically generate reliable NC code, and it was extremely easy to use. Two days training and we could get started.” Since the 1980’s, the machinery used and WORKNC have naturally evolved. Riemann now uses the latest 64 bit parallel processing version of WORKNC to automatically and rapidly program its advanced 3, 4, and 5-axis machines.

从20世纪80年代开始，德国工具制造商Riemann Gmbh就一直使用WorkNC自动CAM数控编程软件。据Riemann Gmbh的创始人回忆，“当时我们看了2-3个CAM软件演示，只有WorkNC让我们印象深刻。WorkNC铣加工策略丰富，我们能够轻松从中选择想要的策略。WorkNC可以自动化产生可靠的NC代码，且操作非常简单。通过两天的培训，我们就可以利用WorkNC进行编程。”从20世纪80年代以来，Riemann Gmbh使用的机床设备和WorkNC软件一直在升级。Riemann Gmbh现在使用的是最新的64位并行处理版本的WorkNC，他能够自动、快速地编辑用于3、4和5轴设备的刀路。

Riemann specializes in stamping and forming tools for the automotive industry for components such as seats and exhaust manifolds, providing a service from tool design through to machining and testing. Where it does not have the facilities in house, it works with partner companies to deliver a complete service package.

Riemann Gmbh擅长制造汽车行业的冲压模，例如汽车座椅、排气歧管，提供从模具设计至加工和测试的服务。对于无法生产的部件，Riemann Gmbhye 则会和合作的公司为客户提供完整的服务。

The company has made a considerable investment in milling capability and has settled on DMG / MORI SEIKI as its preferred machinery supplier. It has a 3-axis DMU 125T and several 5-axis machines including a DMC 75V, two DMU 200Ps and a 6 meter DMU 600P. Rene Luttmann, Project Manager says, “5-axis milling is standard practice nowadays. We generally cut as much as we can in 3-axis at each 5-axis inclined position. Continually rotating our heavy workpieces would greatly slow down machining. Firstly, we machine the base of the tool and then change the setup so that we can machine all the other geometry and contoured 3D surfaces in one operation, significantly reducing our cycle times.”

Riemann Gmbh在提高铣加工能力方面投资了很多，并把德马吉森精机作为稳定的设备供应商。Riemann Gmbh已拥有三轴DMU 125T机床和好几台五轴机床，包括1台DMC 75V、2台DMU 200Ps以及1台的6 米DMU 600P。Riemann Gmbh的项目经理Rene Luttmann说，“如今，五轴铣床已成为标准加工方式。我们通常会在五轴倾斜的位置尽可能用三轴进行切削。机床不断持续旋转沉重的工件会大大降低加工效率。首先，我们加工模具基座，然后更改设置，这样我们能够在一次操作中加工所有其他的几何形状和轮廓3D表面，大大缩短了我们的周期。”

The company’s WORKNC programmer, Mark Hildebrandt starts with CAD files from CATIA V5 and uses his expertise to optimize the WORKNC cutting paths for speed and quality. “One reason why we have been working with WORKNC for over 20 years is the large number of efficient milling strategies included in the software. In particular, we find the rest material cycles extremely practical and efficient, as they avoid air cuts and shorten machining times.” WORKNC makes it easy to fine-tune NC programs. He continues, “I can edit milling programs and cut and paste elements, such as a proven milling strategy, into a new program.”

Riemann Gmbh的WorkNC编程人员Mark Hildebrandt说编程工作从导入CATIA的CAD文件开始。与此同时，Mark Hildebrandt利用多年积累的的专业知识去优化WorkNC刀路以提高速度和质量。“我们和WorkNC合作超过20年的一个原因是WorkNC包含了大量高效的铣削策略。尤其我们发现WorkNC去除余料特别实用和高效，因为WokNC避免了空刀和缩短了加工时间。” WORKNC使对NC程序进行微调变得很容易。他持续说道，“我们能够编辑铣削程序，剪切和粘贴其中的元素，例如已被验证的程序至新的程序。”

Recently, Riemann has added WORKNC’s automatic feature recognition for hole drilling. Rene Luttmann says, “Stamping tools have a considerable number of holes and we can automatically cut these in WORKNC. First, the software finds the hole features and coordinates from the CAD data. Next, it generates tailored machining strategies which use the tools that are actually available. This minimizes the number of cutters we need to stock and eliminates the possibility of an error, delivering valuable cost and time savings.”

最近，Riemann在钻孔中应用了WORKNC自动化特征识别孔功能。Rene Luttmann说，“冲压模有很多孔，WorkNC能够让我们自动完成孔加工。首先，WorkNC识别来自CAD数据中的孔的特点和坐标。然后，WorkNC生成使用实际可用模具的定制加工策略。这样降低了我们需要储存的刀具数量，消除了存在错误的可能性，节省了宝贵的成本和时间。”

The DMU 600P has greatly expanded the capacity at Riemann, which now offers subcontract machining services as well as tool making. It can now handle workpieces up to 40 tons using simultaneous 5-axis machining strategies. Klaus Riemann says, “We purchased the machine to meet our tool making needs, but its 6 meter travel also enables us to machine any huge component with 3D contours from several sides without reclamping. With these techniques and WORKNC’s 5-axis strategies we can easily save two hours of setup time. The demand for very large parts is increasing and previously we delivered it using external service providers, which was both expensive and complicated. The in-house capacity we now have is not very common so we are delighted that we can offer our customes these new capabilities.”

DMU 600P大大扩大了Riemann的加工能力，为Riemann提供分包合同加工服务和模具制作。DMU 600P利用5轴加工策略能处理多达40吨的工件。Klaus Riemann说，“我们采购DMU 600P就是为了满足模具制造的需要，但是它的六米行程也能够让我们从多个侧面加工任何具有3D轮廓的大工件，且不需要重新装夹。我们使用这些技术和WorkNC的5轴策略能够轻松节省2个小时的设置时间。对于大型工件的需求正在增加。此前，我们通过外部服务供应商完成交付，价格昂贵且复杂。我们现在已具备了内部加工能力，所以我们很高兴能够为我们的客户提供服务。

As well as WORKNC, Riemann also uses WorkXPlore, the high speed 3D viewer. This system enables many more people within the company to simultaneously access and interrogate the design data. It can quickly handle and manipulate very large CAD files from leading design systems and is used by the company for purchasing, quotations, sharing data on the shop floor and, in parallel with the CAD system, for tool design.

除了使用WorkNC之外，Riemann也使用3D高速浏览器WorkXPlore。WorkXPlore能够让更多公司的内部人员同时访问和查询设计数据。WorkXPlore能够快速处理和操作来自设计软件的大型CAD文件以及用于公司采购、报价、车间数据分享、并行与CAD软件用于模具设计等。
