Abstract
This paper, firstly, describes the generation of small pitch parallel line chatter marks on the workpiece surface. Experimental results show that the pressure pulsation produced by the vane pump makes the wheelhead and the work table of the machine vibrate which results in small pitch chatter mark formation. The installation of an in-line type accumulator to the hydraulic line is effective in suppressing this type of chatter mark. Secondly, the causes of the unexpected change of the chatter mark pattern corresponding to the wheel rotation are also investigated. It is found that the speed and stroke of the work table and the hydraulic oil temperature vary with operating time. As a result, the chatter marks may change their appearances in spite of constant machine settings. It is also found that by using the developed special control device, it has been possible to keep the speed and stroke of the work table constant and also to obtain the most preferable chatter mark pattern.
