Within the increasing of competitive and demand for quality product in the market place, therefore the demands for quality for metal cutting are getting higher, one of them are turning process. The quality of the product can be seen from the surface roughness and material removal rate. Surface rougness have a affect in functional product. The more smaller in roughness, the quality is more better. Material removal rate in the machining process is very important because it relates to dimensional accuracy in tool, dies serta mold. This research using parameter related to turning such as spindle speed, feed rate and depth of cut for material SKD 11 using chisel CNMG.

Abstract

The world of the manufacturing industry continues to develop and one of the technologies that support the manufacturing industry in the era of the industrial revolution 4.0 is 3D printingtechnology. It is very important to know the mechanical properties of 3D printing materials, one of which is tensile strength. Low tensile strength causes the product to experience mechanical failure such as yielding and fracture. High surface roughness causes the wear of components and affects their functional factors. To get a product of good quality so that the resulting product has high tensile strength and low surface roughness, research is needed to find the right and optimal combination of process parameters in the 3D printing process. Tensile strength and surface roughness will be observed. The material used is ABS filament. Layer height, infill pattern, and nozzle temperature are varied. Design of Experiment using the Taguchi method in the form of an orthogonal matrix L9(34) with three replications and using Grey Relational Analysis. From the results of the study, it was found that the most optimal combination of independent variables for the response variables of tensile strength and surface roughness simultaneously was layer height at level 1 with a value of 0.1 mm, infill patternat level 2 with line pattern and nozzle temperature at level 1 with a value of 230°C. The layer height parameter gives a contribution percentage of 49.55%, infill pattern 46.92%, and nozzle temperature 1.67%.

Abstract

Laser cutting machine is able to cutting hard material and having complicated patterns. In the cutting process in the laser cutting machine has several parameters, they are the laser beam focus point, cutting gas pressure and cutting speed. These parameters can cause cutting defects. Starting from the roughness surface until the product is not cut. So we need an optimization process through research methods. The optimization method in this research use the L9(34) orthogonal matrix with 3 levels on each parameter of taguchi and neural network prediction. From the taguchi optimization process, it produces an optimal parameter combination for the surface roughness response at the laser beam focus point -14 mm, gas cutting pressure 17 bar and cutting speed 0.4 m / min. And for the response of the cutting rate at the laser beam focus point -17 mm, gas pressure cutting 20 bar and cutting speed 0.6 m / min. While the optimal parameter settings using a neural network, for the response of surface roughness at the laser beam focus point -14 mm, gas pressure cutting 20 bar and cutting speed 0.2 m / minute. And for the response of the cutting rate at the laser beam focus point -20 mm, gas pressure cutting 17 bar and cutting speed 0.6 m / minute. In optimal parameter settings using the taguchi method, the laser beam focus point parameters have the greatest contribution, with a percentage of 46.5061% for the response of surface roughness. While cutting speed has a significant contribution in reducing the variation of the cutting rate response, with a contribution percentage of 66.0430%.

Abstract

Determining the combination of machining parameters is very important. The right machining parameters can produce optimal machining performance. EDM sinking is used to produce automotive components, aerospace, molds, and dies. AISI P20 is material that is widely used by manufacturing industry for dies and mold because of its hardness and resistance to heat. Based on these reasons, optimization is carried out to get appropriate parameter combination for the EDM sinking process using AISI P20. Process variables in this study are type of electrode, gap voltage, on time, and off time which aims to produce optimal response. Response variables observed were material removal rate, surface roughness, and electrode wear rate. Based on Taguchi method, matrix orthogonal L18 (21 × 73) was chosen for design of experiment. Taguchi method and Grey Relational Analysis used to optimize multiple responses simultaneously. Parameter optimum condition could be obtained by using graphite and setting values of gap voltage 50 volt, on time 250 ?s, off time 40 ?s. Percentage contribution of electrode type is 39,0733% whereas off time give contribution 32,4311%, on time 6,4574% and gap voltage 4,3590%.
