This paper offers an experimental study of the microcutting mechanisms in marble grinding to aid the optimization of the marble grinding process. The necessity for investigating these mechanisms is dictated by the increased use of marble in many applications and the fact that grinding and polishing processes are the dominant technologies used to meet surface finish requirements in this natural material. The experiments are aimed at the determination of the normal component of the cutting force and of the grain traces in microcutting with a single diamond grain. The investigations carried out make provisions for establishing critical grain penetration and cutting depths and allow the prediction of the normal cutting force component as a function of grain penetration speed and depth.

Rough Turning

In this paper, the cutting experiment was used to study the influence of various cutting parameters on cutting force when rough turning titanium alloy (TC4) with the whole CBN tool. The results indicate that among the cutting speed, feed rate and cutting depth, the influence of the cutting depth is the most significant on cutting force; the next is the feed rate and the cutting speed is at least.

A micromilling experimental study on AISI 4340 steel is conducted to understand the micromilling principle deeply. The experimental results, especially on the surface roughness and cutting force, are discussed in detail. It has been found the minimum chip thickness influences the surface roughness and cutting force greatly. Meanwhile, the material elastic recover induces the increase of the axial micromilling force. The average cutting force and its spectrum analysis validate the minimum chip thickness approximation of AISI 4340 is about 0.35μm.

Micro Drilling

With the development of high density, multi-functions, miniaturization and multi-layer on printed circuit board (PCB) design, great challenges have been presented to the miniaturization of drilling on PCB. In order to meet the hole precision, quality and improve the performance, efficiency of mechanical drilling, further research should be done on the cutting state. Kistler high-precision micro-force platform was used in this paper to test and analyze the cutting force, investigate the general laws of micro drilling, and optimize the parameters for HANS PCB drilling machine. Thereby, to improve the efficiency and precision of the drilling, range of processing, and increasing market competitiveness.

Titanium Alloy Ti6al4v

Milling tests were undertaken to analyze and compare the machinability of hydrogenated titanium alloy Ti6Al4V. Uncoated WC-Co tool inserts were used in the study. The feed and the depth of milling were maintained constant, and only the milling speed was varied because it is the most affecting parameter. Results showed that cutting force and tool life were greatly influenced by the contents of hydrogen. Tool life decreased at first and then increased gradually with the increase of hydrogen content, and the maximum magnitude decrease of tool life is about 0.2%H, meanwhile, the maximum tool life is about 0.5%H. However, with the increase of cutting speed, the favorable effect of hydrogen on the titanium alloy machinability would be weakened even disappear, therefore, 50-100m/min would be a suitable choice of cutting speed.
