Abstract:
A friction stir welding system with the flexibility of five axes has developed to join 3-dimensional curved
surface. The features of the hardware of this system are: (1) The tool pressurization by an air cylinder is adopted..
(2) In order to use for various researches, it has two kinds of FSW tool heads. (3)A 3-dimensional coordinate
measuring instrument is installed to teach the weld line. The features of the software for this system are: (a) Weld
line is taught after a work piece is set on the table. (b) The control program is described by NC language. © The
edition of welding conditions and the simulation of the tool path are available. This paper reports the structure and
features of the system, and examples of FSW by the system.
SOFTWARE
New software was developed to control the 3D head.
This software generates NC program which controls
whole joining process of the FSW equipment, based on
the joining path, the weld conditions set through the key
board and the knowledge about FSW technology. By
inputting the NC program into the controller of the
equipment, FSW is carried out automatically. Fig .4
shows the software system for the 3-dimensional FSW.
CONCLUSIONS
The results obtained are summarized as follows.
(I)The 3 dimensional column-type FSW equipment
which is consisted of 5 axes has been developed. The
equipment shows enough performance to join the
multi-dimensional work piece.
(2)Several work pieces with 2 and 3 dimensional were su
ccessfully joined by the FSW equipment.
The teaching method developed in the research can
be applied to other processes such as electric weldin
g robots and coating robots.
