(10,19) The behavior of a variety of CAD/CAM ceramics is being introduced in new concepts such as materials' machinability, which is still not so well defined.
"By increasing the aluminum content of iron to over 0.010% in the presence of strontium and zirconium, we achieved the optimum nucleation that is needed to eliminate the hard carbides that reduce machinability," said Cathrine Hartung, Elkem's R&D engineer who conducted the tests at Kristiansand.
Although improvement in mechanical properties due to such modification is well known [23, 31], the effects of both size of silicon particles and their morphologies on machinability of Al-Si parts remain unknown.
In the present study, cutting force (f) resulting from the machinability of austempered vermicular graphite cast irons (VGCI) is considered as a measurable output parameter with respect to the input parameters, namely cutting speed, feed rate, and hardness.
It was then suggested to change the chemical composition of inoculants used in casting and through machinability tests conducted on the samples, to observe the effect of each addition in the milling properties of the material.
References [4] and [5] give information about the machinability of Inconel 718 and its material properties which are essential for productive machining.
The products technical properties allow common bubble gum technology to be used, with high form stability and reduced stickiness (ensuring easy machinability and cleaning).
His topics include machining processes, the mechanics of orthogonal cutting, cutting cylindrical surfaces, high-speed machining, abrasive finishing processes, machining by electrochemical erosion, micromachining, and machinability. The second edition has been revised in light of comments on the first.
"With the addition of Fluorosint 135 to its line-up of high-performance PTFEs, Quadrant, the industry leader in polymer design and innovation, has responded to the market's urgent need for excellent machinability and stability," the statement added.
