Abstract

The authors report on remote handling tools which have been specifically designed to meet requirements for pipe cutting at JET (Joint European Torus). The principal requirements were the quality of cut necessary for rewelding, effective swarf removal, and compactness for remote handling. The designs of tools had to be compatible with the severe access restrictions imposed by the JET machine. The processes used by the tools are sawing from the inside and outside of pipes, and orbital lathe for larger pipes. Special features were created on the pipes to facilitate tool location. The blade and toolbit designs have evolved to optimize cutting forces and tool durability. Satisfactory reliability has been achieved by performing 200 h of cutting during the two year period of development. Subsequently, over 100 'hands-on' cutting operations have been made on the JET machine since 1988 and a further 150 cuts are planned for 1992. Using a programmable controller the feed rate can be changed throughout the cutting operation into a predetermined way, thereby optimizing the tools' efficiency.<>

设计，开发和使用管材切割工具的远程处理JET

作者报告了专门为满足JET(联合欧洲环)管道切割要求而设计的远程处理工具。主要要求是重焊所需的切割质量，有效去除切屑，以及远程处理的紧凑性。工具的设计必须与JET机器施加的严格访问限制相兼容。工具使用的工艺是从管道的内部和外部锯切，轨道车床用于较大的管道。在管道上创建了特殊功能，以方便工具定位。刀片和钻头的设计已经发展到优化切削力和工具耐用性。在两年的开发过程中，通过200小时的切割，取得了令人满意的可靠性。随后，自1988年以来，在JET机器上进行了100多次“动手”切割操作，并计划在1992年再进行150次切割。使用可编程控制器，进给速度可以在整个切削过程中以预定的方式改变，从而优化刀具的效率。
