检查系统提升精密加工的速度

Renishaw公司的创始人兼董事长David McMurtry先生介绍新推出的高速CMM扫描系统。

据报道,一种高速5轴检查系统的运行速度可以达到当前系统的20倍。Renscan5系统通过双轴无限定位探头进行每秒500mm的扫描,同时坐标测量机(CMM)以恒定的速率进行单轴移动。根据Renishaw公司(英国格洛斯特郡,Wotton-under-Edge;www.renishaw.com)介绍,这种设计有效地消除了CMM动态误差的源头,此种误差使扫描速度只能局限在每秒10到20mm。

小型Revo探头(图中人物为公司创始人兼董事长David McMurtry先生)扫描部件的速度和加速度远优于传统的CMM,同时还避免了因快速加减速移动大型CMM造成的动态误差。该公司表示,超高速扫描将大幅缩短循环时间,并可获取得更多数据,以便满足对部件规格的更高要求。复杂部件的生产需要大量的数据点以进行流程控制和质量确认,该系统将帮助制造商解决此类生产的众多难题。

该公司研制的通用CMM控制器使Renscan5系统和Revo探针可以安装在大多数新式和现有的CMM上。

率先采用了该技术的是一家为喷气式发动机提供变形涡轮机叶片和压缩机的生产商。公司表示,该设备提升了对复杂结构部件的检查和验证速度,这一点对于医疗器械制造业同样有益,特别是对于生产人工关节的部门。
