“…[22] experimentally studied the effects of coatings, tool tip material while bandsawing different work piece material without considering the usage of cutting fluid. Other studies that reported usage of the cutting fluid while cutting materials such as Ti-7, Inconel 718, and medium carbon steels, did not evaluate the effect of the cutting fluids [23][24][25][26]. However, the recent studies by Rakurty et al have shown that the cutting fluid amount, type, and workpiece geometry effects the performance of the band saw blade [10,11].…”

Cutting fluids used in machining have received a lot of attention due to their adverse environmental and economic effects. Researchers have studied cutting fluid usage in traditional machining processes such as turning, facing, milling, etc. However, few studies focused on the cutting fluid used in band sawing applications. This study reports a literature review of the usage of the cutting fluid in band sawing and their sustainable and economic aspects. A review of the literature and industrial data has shown that the majority of band saw blades use high-speed steel as the cutting tool material for cutting metal. This study presents a metric-based sustainability assessment and a detailed analysis of recent economic factors such as the cost of the cutting fluids used in band sawing through industrial case studies. A global survey of the cutting fluid usage in the bandsawing application has shown that the majority of the industry is employing flood coolant application. The flood coolant application cost can be as high as 8% of the total consumables cost of the band sawing process.

“…29 However, very limited literature is available in public domain related to machining with carbide-tipped bandsaws. 30,31 Bandsaw blades for metal cutting are mainly of two kinds, bi-metal blades with the cutting edges made of HSS and carbide bandsaws with tungsten carbide teeth. While carbide-tipped bandsaws have been developed for cutting difficult-to-cut materials, bi-metals are still the most widely used bandsaws for cutting-off operations.…”

The manufacturing industries still face the most challenging job at hand to machine Nickelbased superalloy, Inconel 718, efficiently and economically. In contrast to the extensive research efforts in secondary machining processes such as turning, milling and drilling, very little or no attention is paid on bandsawing of Inconel 718. The paper presents an experimental investigation of machining Inconel 718 using carbide tipped bandsaw teeth in a custom made experimental facility. Cutting forces were measured during the bandsawing operation using a dynamometer and the wear modes and mechanisms in the bandsaw teeth were investigated in a Scanning Electron Microscope (SEM). Three different feeds or depths of cut (10 μm, 20 μm and 30 μm) were employed with a cutting speed of 30 m/min during the machining tests. At smaller feed or depth of cut (10 μm), abrasive wear, adhesive wear and some degree of plastic deformation were identified as the governing mechanisms of tool wear. The higher depth of cut (30 μm) could cause cracking, chipping or premature failure of the carbide tip in bandsaw tooth. Strong welding of workpiece material to the cutting edge formed a built-up-edge (BUE), which would impair the bandsawability due to the modification of the cutting edge. The higher depth of cut significantly improved the machining performance due to the reduction in specific cutting energy. However, it was not recommended to apply higher depth of cut as there were obvious possibilities of premature tooth failure. Machining force and specific cutting energy results along with chip characteristics were correlated with the tool performance and tool wear. The results of this investigation would be helpful for bandsaw manufacturers and end users to get a fundamental understanding of the bandsawability of Inocnel 718 with the carbide tipped bandsaw.
