The present research work aimed to study the effects of cutting environments and conditions on tool wear and residual stresses induced by orthogonal cutting of AA6061-T6. Cutting environments included dry- and flood-coolant modes and cutting conditions consisted of cutting speed and feed rate. A 2D finite element (FE) model was developed to predict tool wear and residual stresses and was validated by experimental measurements including machining forces, tool wear, and residual stresses. This was obtained by exploring various magnitudes of the shear friction factor and heat transfer coefficient and choosing proper coefficients using the calibration of the predicted results with the measured ones. The experimental results showed that the effect of cutting environment including dry and flood-coolant modes was negligible on machining forces. The experimental investigation also demonstrated that increasing feed rate raised machining forces, tool wear and residual stresses in both cutting environments. Low Speed Cutting (LSC) led to the highest value of tool wear and High Speed Cutting (HSC) provided the lowest values of resultant machining forces and residual stresses in both modes. Flood-coolant mode reduced tool wear and slightly decreased tensile residual stresses in comparison with dry mode. As a result, low feed rate and high-speed cutting under flood-coolant mode were proposed in order to improve tool wear and residual stress in orthogonal cutting of AA6061-T6.

“…Data aus dianalisis untuk memprediksi masa pakai pisau TC. Salah satu pendekatan untuk memprediksi masa pakai pisau adalah menggunakan persamaan Taylor (Hosseinkhani & Ng 2020). Persamaan ini menunjukkan hubungan eksponensial antara masa pakai pisau dengan kecepatan pemotongan (Li 2012).…”

The scarcity and high cost of high-quality sawn timber has resulted in the switching of furniture industry to using composite wood such as medium density fiberboard (MDF) as the raw material for its products. One of the factors that affect production costs and product quality in the furniture industry is the quality of the cutting tool used in the cutting operation. The quality of the cutting tool could be improved through the addition of coatings on the surface of cutting tool (surface coating). The purpose of this study was to determine the life time of AlCrN, TiAlN, and TiN coated tungsten carbide (TC) tools in cutting MDF. Cutting operations were performed on a computer numerical control (CNC) router machine at feed per revolution (Frev) of 0,10, 0,15, 0,20, and 0,30 mm/rev. The TC cutting tool life was determined based on its wear and was calculated using the Taylor tool life formula. The results showed that coated TC cutting tool provided a better wear resistance and longer life than uncoated TC cutting tool. The low of Frev set in cutting MDF resulted in a lower wear and longer life of cutting tool. AlCrN coated TC cutting tool provided the best wear resistance and longest life, thus it promising to be developed and used in cutting MDF. Keywords: coated cutting tool, medium density fiberboard, surface coating, tool life, wear

Umur alat potong sangat bergantung pada parameter pemotongan. Terdapat beberapa parameter pemotongan seperti kecepatan potong (Vc), pemakanan (fz), kedalaman pemakanan (a), dan beberapa kondisi lingkungan yang dapat berpengaruh terhadap proses pemotongan. Umur alat potong dapat dibuat panjang dengan menurunkan kecepatan potong, pemakanan, dan kedalaman pemakanan, tetapi hal tersebut dapat memengaruhi produktifitas dari proses pemesinan. Kecepatan potong sangat memengaruhi umur alat potong berdasarkan persamaan Vc.Tn = C. Nilai n pada persamaan Taylor menunjukan material alat potong yang digunakan. Material alat potong yang digunakan pada penelitian ini adalah kabida tungsten (WC) dengan pelapisan titanium karbonitrida (TiCN), benda keda kerja yang digunakan adalah S50C. Tujuan dari penelitian ini adalah menentukan persamaan Taylor untuk proses bubut. Proses pembubutan dilakukan dengan memvariasikan kecepatan potong, sedangakan parameter lain seperti kecepatan pemakanan dan kedalaman pemakanan dibuat konstan. Hasil eksperimen tersebut kemudian dibuat grafik kecepatan potong terhadap dimensi keausan alat potong. Hasil dari penelitian ini dapat digunakan sebagai referensi untuk menentukan parameter pemesinan dengan laju keausan alat potong yang diinginkan, persamaan Taylor dari hasil penelitian ini adalah Vc.T0,48=847,09.
