摘要： Processes for high speed machining of workpiece materials using high performance tools with prolonged tool life and improved surface finish are provided by vibrating the tool and/or the workpiece at a frequency greater than the frequency of shear localization in the primary shear zone or chip segmentation occurring in the absence of tool vibration, with an amplitude sufficient to break up the tool-chip atomic contact, thereby decreasing the tool-chip contact length through decreasing the tool-chip contact time, thereby suppressing accelerated chemical tool wear caused by dissolution of the tool into the workpiece by nanocrystalline grain boundary diffusion and grain boundary sliding mechanisms by preventing shear localization associated with nanocrystalline grain formation in the primary shear zone of the chip, and suppressing oxidation wear of the tool by preventing segmentation of the chip.

摘要： A process for producing compacted graphite cast iron thin walled shaped castings in a high productivity line is provided which comprises: (i) forming a near eutectic melt of cast iron, having a low sulfur content, preferably around 0.01% by weight; (ii) adding to the melt sufficient graphite stabilizing agents such as silicon to suppress the carbide eutectic formation at the large undercooling characteristic of thinner sections of the castings; (iii) admixing at least one rare earth containing additive with said melt to form rare earth compounds so as to reduce and maintain the Henrian oxygen activity in the melt at about 10.sup.-6 ; (iv) inoculating the melt in an optimum manner to promote the required degree of interconnected vermicular graphite growth, and (v) casting the resulting melt. The nucleation step is better controlled by inoculating each mold individually just prior to casting, by inoculating the molten metal as it enters the mold, or in the path of molten metal at the pouring basin, sprue or between sprue and ingate in the mold.
