Penelitian ini bertujuan untuk mengkarakterisasi lapisan diamond-film yang digunakan sebagai bahan pelapis pahat karbida khususnya bahan pelapis (diamond-film CVD), sehubungan dengan adanya laporan penelitian perihal kegagalan fungsi dari bahan pelapis pahat karbida yang digunakan pada proses pemesinan kering bahan non-ferro metal pada awal proses pemotongan berlangsung (initial wear). Kajian karakteristik lapisan diamond-film pahat dilakukan melalui pendekatan beban mekanik melalui proses pemesinan kering menggunakan bahan paduan aluminium 6061. Kondisi pemotongan yaitu v= 350 m/min; f= 0.15 mm/put; a= 1.5 mm pada fasa Initial-wear (tc= 1.736 min). Uji beban mekanik menggunakan bahan uji berkekerasan berbeda, Aluminium 6061 (53.3 HRB/95 HV) dan AISI 1070 (93.3 HRB/200 HV), hasil pengujian pada bahan uji Aluminium 6061 diperoleh keadaan Aus-abrasive VB= 0.070 mm, dan pada bahan uji AISI 1070 diperoleh keadaan Aus tepi VB= 0.250 mm, analisa menggunakan scanning electron microscope (SEM) dan energy dispersive analysis X-Ray spectroscopy (EDAX), hasil pengujian diperoleh sebaran unsur pelapis diamond-film pada bahan uji Aluminium 6061 terhadap kondisi pemotongan diperoleh keadaan unsur material pelapis diamond film masih signifikan. Kemudian pada bahan uji AISI 1070 terhadap kedua kondisi pemotongan diperoleh keadaan unsur material pelapis diamond-film signifikan. Dari hasil penelitian disimpulkan bahwa pendekatan beban mekanik tidak ditemukan peristiwa pengelupasan lapisan diamond-film pahat karbida, fenomena yang terjadi terhadap ketiga pendekatan yang dilakukan adalah peristiwa hilang bertahapnya sebagian volume material pelapis diamond-film yang melapisi material substrate akibat Aus pengikisan lapisan (abrasive-coating wear).

The purpose of the research was to characterize diamond-film coating which is used as carbide tool coating material, especially coating material (diamond-film CVD) and substrate material (WC/Co) in general approach interaction of chemically, This is related to the research which reported about the functional failure of carbide tool coating material, used in dry machinery process of non-ferro metal in the initial wear. The study on the characteristics of tool diamond-film coating was conducted through chemical interaction approaches which occurred between the working object and tool through dry machining process. Cutting condition was v= 350 m/min; f= 0.15 mm/put; a= 1.5 mm in Initial-wear phase (tc= 1.736 min). The result of the test was abrasive wear VB = 0.070 mm. Chemical load was tested through micro analysis using energy dispersive analysis X-Ray spectroscopy (EDAX), the result of the test was the distribution of diamond-film coating elements in aluminum 6061 testing material on the cutting conditions indicated that diamond-film coating material was still significant. The conclusion of the study was that by using chemical interaction approaches, was no coating delamination in diamond-film coating of carbide tool. The phenomenon of the three approaches was the gradual disappearing of a part of the volume of diamond-film coating material which layered substrate material as the result of abrasive-coating wear.

In metal cutting processes, the source of surface integrity deviation is a combination of several factors. The surface roughness parameter (Ra) is sufficient to determine the quality level of the surface packaging of a product, so it is widely used as a parameter to determine the surface packaging level of a product. Carbide tools dominate modern applications in the metalworking industry and are the preferred choice for metal cutting processes. Carbide tools can be improved through a coating process. In particular, the purpose of this study was to obtain surface roughness and optimum cutting conditions for dry machining of AISI 1045 materials using coated carbide tool when used in dry machining as well as for the development of research and development with research design analysis of the results of student practicum processes in laboratories, especially surface packaging material analysis.

The peg is a component that functions as a binder between the shaft and the hub in transmitting power and rotation. In general, the pegs are designed and made using metal materials such as mild carbon steel. In this research, the material of the coupling pin design on the centrifugal pump shaft is S45C. Where on the sample of the designed post, an impact test or the Charpy method of hitting the notch is carried out which aims to determine the amount of resistance to sudden loading and to determine the physical changes (failure modes) experienced by the post material. In this study, the sample of the post with dimensions of 6.10 mm x 6.10 mm x 55 mm obtained a large impact strength (impact strength) in the Charpy method impact test of 0.8445 Joule/mm2. And for the physical change (failure mode) experienced by the post material against the sudden loading, it is a brittle fracture that is characterized by physical characteristics in the form of granular (like sand) on the fracture surface, and the absence of plastic deformation that occurred first.

A digester is a piece of equipment consisting of a cylindrical tube with both long and short knives. This tool is used to aid the processing by slicing and stirring, making the fruit soft. Common issues with digesters usually involve wear and breakage of the digester knives. Wear is generally understood as the loss of material due to the mechanical interaction between two moving and loaded surfaces. Wear can disrupt the production process, affecting the company's productivity. The objective of this research is to determine the volume and rate of wear on the long arm of a cast steel digester. Based on this study, the wear value obtained for the long arm digester is a wear volume of 19,117,969 mm³ and a wear rate of 9,558.984 mm³/hour under a load of 23,520 N over 2,000 hours of operation. This indicates that the replacement of the long arm digester should be performed according to the specified operational time limits while considering the load entering the digester, in order to prevent a decrease in the company's productivity.

In coated carbide cutting tools, the coating layer functions as a solid lubricant that improves wear resistance and minimizes frictional and thermal effects during machining. This study investigates the influence of machining parameters on cutting performance and characterizes the coating material and WC/Co carbide substrate to better understand their relationship with tool wear behavior. The machining parameters were established through an experimental design that evaluated mechanical loading, thermal loading, and chemical interactions using microstructural analysis. The experimental design evaluated the effects of mechanical loading, thermal loading, and chemical interactions through wear and microstructural analysis. Under mechanical loading, machining of Al-6061 produced mild abrasive wear with flank wear (VB) of 0.07 mm, while AISI 1070 generated higher edge wear of 0.25 mm. Under thermal loading, a 20% increase in cutting speed resulted in VB of 0.10 mm for Al-6061, whereas a 20% reduction in cutting speed for AISI 1070 produced VB of 0.16 mm accompanied by plastic deformation. Chemical interaction analysis showed stable coating integrity without delamination during Al-6061 machining. In contrast, AISI 1070 machining caused partial diamond film loss and substrate exposure, with approximately 35% diamond film remaining after wear progression. The results indicate that tool wear behavior is mainly controlled by mechanical loading, while thermal and chemical effects remain secondary. Abrasive wear was identified as the dominant wear mechanism, causing progressive coating removal without catastrophic delamination.
