Neuro-fuzzy based predictive model for cutting force in CNC turning process of Al–Si–Cu cast alloy using modifier elements

Abstract

This study investigated the predicted cutting force model of a turning operation for Al–Si–Cu cast alloy modified with modifiers based on adaptive neuro-fuzzy inference system (ANFIS) approach. Feed rate, cutting speed and Silicon spacing were considered as the input parameters. A series of turning experiments were conducted at various feed rates and cutting speeds. The prediction result showed that the ANFIS model successfully predicted the cutting force value in terms of cutting speed, feed rate and Si spacing. A mathematical model was proposed to describe the cutting force changes during the machining of Al–Si–Cu cast alloy. Moreover, the addition of Bismuth into the base alloy decreased the cutting force compared to other refinement elements.

Machinability studies of Al–4Mg/in-situ MgAl2O4 nano composites: measurement of cutting forces and machined surface roughness

“…Studying the chip morphology has a major impact on the machining process as it affects the cutting force, surface integrity, tool and workpiece conditions [33][34][35]. Studies have proved that the morphology of chips has a major role in defining the life of cutting tool and workpiece [36][37][38]. During the chip removal process, a part of the temperature removed is taken away with the thrown away chip and any variation in the formation of chip size and shape would affect the life of cutting tool and workpiece [39][40][41].…”

CVD-TiCN/Al2O3/TiN Kaplamalı Kesici Uç ile Al-12Si-(0,02-1)Sr Alaşımlarının Tornalanmasında Kesme Kuvveti ve Yüzey Pürüzlülüğü Üzerine Deneysel Çalışma

“…Marani vd., kokil kalıba döküm yöntemi ile üretilmiş Al-Si-Cu alaşımının tornada işlenmesinde stronsiyum (Sr), Bizmut (Bi) ve Antimon (Sb) ilavelerinin kesme kuvveti üzerindeki etkisini incelemişlerdir. Sr ilavesi ile kesme kuvveti artarken Bi ilavesi ile kesme kuvvetinin azaldığını ve ANFIS (Adaptive neuro-fuzzy inference system) ile optimum kesme şartları olarak maksimum kesme hızı (250 m/dak) ve minimum ilerleme (0,05 mm/dev) kombinasyonunun kullanılması gerektiğini tespit etmişlerdir [11]. Kumaran vd., Al-Si7Cu4 alaşımının sementit karbür kesici uç ile farklı kesme hızı (800, 8500 ve 9000 dev/dak), ilerleme (0,6125; 0,634 ve 0,645 mm/dev), kesme derinliği (0,4; 0,6 ve 0,8 mm) ve uç yarıçapı (0,5; 0,75 ve 1 mm) kullanarak frezelenmesinde kesme parametrelerini yüzey pürüzlülüğü, talaş kaldırma oranı, artık gerilme ve talaş kalınlığı performans kriterlerine göre optimize etmişlerdir.…”
