Micromachining allows the production of parts and components on a micro scale with high precision has become key process to meet growing demand for components. To quality requirements generated surfaces reduce cutting forces, strategies have been analysed, such as use fluid. Therefore, this research aimed verify effect frequency fluid during micro-milling Inconel 718 alloy. For purpose, an ultr...

The “Haptic Scissors” is a device that creates the sensation of cutting in virtual environments. The scissors have two degrees of freedom of motion and force feedback, one for cutting (single blade rotation) and one for translation. An algorithm was developed to simultaneously display translational and cutting forces for a realistic cutting simulation. In previous work, we used filtered data fr...

Original scientific paper In this paper, the orthogonal cutting force model is proposed comprising forces due to flank wear in addition to the forces for chip formation during the hard turning of round bar made of steel 60WCrV7 hardened at 55+2HRc. Cutting force model includes two tool conditions: perfectly sharp tool with VBB = 0 and tool with maximum permissible flank wear VBBmax. Based on cu...

Gear skiving is used as a gear finishing process to reduce distortion errors which occurred on the gears due to the heat treatment. This process is similar to gear hobbing but the difference is that the cutting tool has a negative rake angle and tooth rake offset. The present study simulates the kinematics of the cutting process with the aid of commercial CAD software and allows the precise det...

The machining of fibre reinforced composites is an important activity for optimal application of these advanced materials into engineering fields. During machining, any excessive cutting force has to be avoided in order to prevent any product reject in the last stages of production cycle. Therefore, the ability to predict the cutting forces is essential to select the process parameters necessar...

Boring is a frequently employed finishing operation in machine shops. Boring is a process in which pre-drilled holes or holes in cast, forged or extruded components are enlarged or finished with a cutting tool mounted on a boring bar. The process is mostly used in applications where close dimensional tolerances and good surface finish are required. In this research work based on the theoretical...
