03 Nov 1983TL;DR: In this paper, the Gauss-Jordan elimination is used to find the solutions to simultaneous equations, whereby all set point settings are simultaneously adjusted by adding such anticipations, and the decoupling of individual process variable changes, by set point setting changes, is effected through anticipation of the interaction through the process.
Abstract: Process control is disclosed, applicable in particular to fluid flow distribution, by which decoupling of the individual process variable changes, by set point setting changes, is effected through anticipation of the interaction through the process, using Gauss-Jordan elimination to find the solutions to simultaneous equations, whereby all set point settings are simultaneously adjusted by adding such anticipations.

TL;DR: In this paper, investigations were carried out on the machining of AISI D2 tool steel under conventional EDM and cryogenically cooled EDM process (CCEDM), the input process parameter such as current (Ip), pulse on time (Ton) and gap voltage (V) were investigated and the output responses like electrode wear ratio, metal removal rate and surface roughness were explored.
Abstract: Electrical discharge machining (EDM) is a well-established machining option for manufacturing geometrically complex or hard material parts that are extremely difficult-to-machine by conventional machining processes. In this research work, investigations were carried out on the machining of AISI D2 tool steel under conventional EDM and cryogenically cooled EDM process (CCEDM). The input process parameter such as current (Ip), pulse on time (Ton) and gap voltage (V) were investigated and the output responses like electrode wear ratio, metal removal rate and surface roughness were explored. Experiments were conducted using L18 orthogonal array in EDM machine. Experimental results showed reductions in the electrode wear of 16% over CCEDM process. A grey relational analysis was used to solve the EDM process with multi performance characteristics to optimize EDM parameters.

TL;DR: In this paper, the effect of process parameters of carburizing heat treatment, such as time, temperature, volume fraction of methane, and flow rate of mixed gases on cobalt gradient structure in functionally gradient WC-Co was investigated.
Abstract: Functionally gradient WC–Co hardmetals not containing η phase with a Co depleted surface layer can be produced by heat treating WC–Co in a carburizing atmosphere. This study investigates the effect of process parameters of carburizing heat treatment, such as time, temperature, volume fraction of methane in carburizing atmosphere, and flow rate of mixed gases on cobalt gradient structure in functionally gradient WC–Co. Taguchi method is used to formulate the experiment layout, and the range analysis and the analysis of variance are employed to determine the optimal process parameter levels and to analyze the effect of parameters on cobalt gradient structure. The results indicate that the order of significance of the parameters on both thickness and amplitude of cobalt gradient is temperature followed by volume fraction of methane, time and flow rate of mixed gases. Both the thickness and the amplitude of the gradients increase with increasing temperature and time, and decrease with increasing volume fraction of methane, and first increase then decrease with increasing flow rate of mixed gases. Finally, the optimal combination of process parameters for fabricating functionally gradient WC–Co composites is determined.
