Penelitian ini dilakukan untuk mengetahui pengaruh penerapan CAD /CAM terhadap proses penggilingan CNC terhadap kekasaran dan ketelitianpermukaan. Spesimen dibuat dengan menggunakan tujuh jenis prosespemotongan. Terdapat face milling, pocket milling, profile milling, slotmilling, pengeboran, thread milling dan surface contouring. Hasil penelitianmenunjukkan bahwa penerapan CAD / CAM dengan variasi prosespemotongan menghasilkan nilai kekasaran yang lebih rendah daripadatanpa penerapan CAD / CAM. Nilai kekasaran permukaan untuk masingmasingproses pemotongan adalah proses face milling (0,5028 μm; 0,5132μm), slot milling (0.664 μm; 0.6556 μm), profile milling (1.282 μm; 1.3128μm), pocket milling (1.3852 μm; 1.4856 μm ) Dan proses pengeboran(1.9944 μm; 2.1136 μm). Nilai rata-rata dimensi dari pengukuranmenunjukkan selisih antara hasil implementasi CAD / CAM dan tanpaimplementasi CAD / CAM. Persentase perbedaan panjang dan lebarmasing-masing 0,037%; 0,059% untuk profile milling; 0,039%; 0,061%untuk pocket milling; Dan 0.151%; 0,317% untuk pengeboran Penggunaanstatistik penerapan CAD / CAM tidak secara signifikan mempengaruhi nilaikekasaran permukaan namun memiliki pengaruh signifikan terhadapketepatan produk dengan tingkat presisi 95%.

Cutting capacity can be seriously limited in heavy duty face milling processes due to self-excited structural vibrations. Special geometry tools and, specifically, variable pitch milling tools have been extensively used in aeronautic applications with the purpose of removing these detrimental chatter vibrations, where high frequency chatter related to slender tools or thin walls limits productivity. However, the application of this technique in heavy duty face milling operations has not been thoroughly explored. In this paper, a method for the definition of the optimum angles between inserts is presented, based on the optimum pitch angle and the stabilizability diagrams. These diagrams are obtained through the brute force (BF) iterative method, which basically consists of an iterative maximization of the stability by using the semidiscretization method. From the observed results, hints for the selection of the optimum pitch pattern and the optimum values of the angles between inserts are presented. A practical application is implemented and the cutting performance when using an optimized variable pitch tool is assessed. It is concluded that with an optimum selection of the pitch, the material removal rate can be improved up to three times. Finally, the existence of two more different stability lobe families related to the saddle-node and flip type stability losses is demonstrated.

Important Object

High speed milling is a newly developed advanced manufacturing technology. Surface integrity is an important object of machined parts. Surface roughness is mostly used to evaluate to the surface integrity. A theoretical surface roughness model for high face milling was established. The influence of cutting parameters on the surface roughness is analyzed. The surface roughness decreases when the cutter radius increases, total number of tooth and rotation angular speed, while it increases with the feeding velocity. The high speed face milling can get a smooth surface and it can replace the grinding with higher efficiency.

As a typical high strength material, titanium alloy Ti-6Al-2Sn-4Zr- 2Mo-0.1Si (TA19) is used to manufacturing the compressor power-brake of aircraft engine and the aircraft skin. All the machining experiments were carried out on a CNC-milling center under the stable conditions of cutting speed, feed rate, and depth of cut. The performance and wear mechanisms of coated- and uncoated carbide tools have been investigated in this paper to evaluate the machinability of TA19 in face milling. The three tools used were PVD-TiN+TiAlN, CVD-TiN+Al2O3+TiCN and uncoated carbide inserts. The results indicated that PVD coating had the best performance than other tool materials in milling titanium alloy TA19, and the cutting force and the wear value were the smallest than that for CVD-coated and uncoated tools. The failure types of PVD-, CVD- and uncoated inserts were the crater wear and micro tipping; the crater wear and tipping; tipping. Abrasive wear and adherent wear were the predominant mechanism of PVD-TiN+TiAlN carbide insert in face milling TA19 alloy. For CVD- and uncoated carbide, adherent wear was predominant.
