“…3,[42][43][44][45][46] With equations (3) and (4), the decrease rate of active abrasive-grain number might be larger than the increase rate of F 1x or F 1z forces, leading to the decrease in the cutting forces. 27,30,37 . In addition, it was also reported that in general grinding process, the smaller abrasive grain has faster wear rate, leading to the increase in the cutting forces.…”

“…However, the effects of the increase in the number of active abrasive grains might have overridden the effects of the decrease in F 1x or F 1z , resulting in the cutting forces using the tool without slots being higher than using the two-slot or four-slot tools. 27,30,37 Another possible reason was that more active abrasive grains led to larger active cutting contact, resulting in higher cutting forces in both the directions (F x and F z ). 50 In addition, the slots on the tools would increase the coolant flow rate, decreasing the friction force at the interface between the tool (end face and outside face) and the workpiece.…”

“…In equation (3), the decreased rate of the number of active abrasive grains might have smaller influence on F x than the increase in F 1x , resulting in using the concave tool generating the highest F x . 27,30,37 In addition, it can be seen from Figure 12 that when using the convex tool, the cutting force perpendicular to the major cutting contacting interface could be divided into two parts, F# x (F cos a) and F# z (F sin a).

Carbon fiber-reinforced plastic composites have many superior properties, including low density, high strength-toweight ratio, and good durability, which make them attractive in many industries. However, due to anisotropic properties, high stiffness, and high abrasiveness of carbon fibers in carbon fiber-reinforced plastic, high cutting force, high tool wear, and high surface roughness are always caused in conventional machining processes. This article reports an investigation using rotary ultrasonic machining in surface grinding of carbon fiber-reinforced plastic composites in order to develop an effective and high-quality surface grinding process. In rotary ultrasonic machining surface grinding of carbon fiber-reinforced plastic composites, tool selection is of great importance since tool variables will significantly affect output variables. In this work, the effects of tool variables, including abrasive size, abrasive concentration, number of slots, and tool end geometry, on machining performances, including the cutting force, torque, and surface roughness, are experimentally studied. The results show that lower cutting forces and torque are generated by the tool with higher abrasive size, lower abrasive concentration, and two slots. Lower surface roughness is generated by the tool with smaller abrasive size, smaller abrasive concentration, two slots, and convex end geometry. This investigation will provide guides for tool selections during rotary ultrasonic machining surface grinding of carbon fiber-reinforced plastic composites.

Grinding of brittle materials is characterized by a complex removal mechanism of both ductile and brittle removal. Therefore, the traditional force models, which are mainly targeted to metallic materials, cannot be fully applied to the force prediction of brittle materials. This paper will propose a new grinding force model for brittle materials considering co-existing of ductile removal force and brittle removal force. The ductile removal force is mainly composed of rubbing force, ploughing force, and chipping force. However, the brittle removal force is more related to rubbing force and fracture chipping force. The proportional coefficient of ductile removal and crack size will be modeled through a series of experiments under different wheel speed and undeformed chip thickness. The working status for a single grit was separated based on the Hertz Theory and chip thickness modeling of Rayleigh probability density function. Grinding experiments have been undertaken by using a high speed diamond grinder on Silicon Carbide, and the results was compared to the force model predictions for validation. The predictive force model shows a reasonable agreement quantitatively with the experimental force data.
