Improving waviness of bore in precision hard turning by pressurized coolant
(2010) In International Journal of Advanced Manufacturing Technology 49(5-8). p.469-474- Abstract
- Precision hard turning is an emerging innovated machining technology for machining hardened workpiece (60 similar to 62 HRC) with characteristic of better flexibility, high production rate, and cost saving. However, one of problem in this process is that it is difficult to remove the thermal distortion of the workpiece induced by the heat generated during the process, especially in the case of precision hard turning of bore. In this paper, pressurized coolant was used in a precision hard turning of bore, with polycrystalline cubic boron nitride as the tool materials, to reduce the thermal distortion of the machined part such as form error and to improve its waviness.

In this paper, pressurized coolant was used in a precision hard turning of bore, with polycrystalline cubic boron nitride as the tool materials, to reduce the thermal distortion of the machined part such as form error and to improve its waviness. The pressurized coolant jet was directly delivered under the chip on the rake face. Experimental result indicated that form error induced by the heat has been reduced, and waviness of the bore was improved with use of pressurized coolant. Crater wear is smaller under pressurized coolant compared to dry cut due to lower rake face temperature and shorter contact length between chip and workpiece. (Less)
