In CNC (computer numerical control) programs, cutting tool needs to move along a path described by a sequence of curves starting from the predefined Cutter Location (CL) points. In this article, cycle time is minimised and cutting forces are limited by a threshold for toolpath generation. In order to determine the cutting forces in each direction f...

... conventional machining experiment, the feedrate was assumed to be constant at 48 mm/min. Constant and scheduled feedrate values are presented in Figure 2. It is seen that feedrate can be increased up to three times in certain portions of the toolpath by the forced based feedrate scheduling technique. ...

Tool condition monitoring, such as tool wear and breakage, is an essential feature in smart manufacturing system. One of most potential sensors that can be used in tool monitoring is vibration sensor, which usually assembled at tool shank. However, in case of CNC turning with rotating tool turret, it is impossible to assemble the vibration sensor a...

Variable pressure angle (VPA) hob is an important cutting tool for generating the twist-free tooth flanks on a crowned involute helical gear used in the high precision gear boxes. However, an appropriate method for generating the VPA hob surface has not proposed yet. Therefore, this paper presents a worm grinding method for generating the helical s...

In this study, the effects of microstructure differences obtained with the application of different spheroidizing heat treatment cycles on medium carbon steel on cutting forces and surface roughness values were investigated. For this purpose, a group of AISI 1050 materials was annealed at 700 degrees C below A(c1). temperature for 720 min and cemen...

This paper presents a methodology for automatic generation of Computer Numerical Controlled (CNC) codes of milling operations. Machined features are used as the basis to input the required data for machining. The most commonly used machined features are studied in this paper. These features are: slot feature, pocket feature and hole feature. Cuttin...

One of the main purposes in machining is to bring surface roughness to the top level. The stage where the most decisive work can be done in improving the product quality is the parameter design phase for both product and process design. In order to determine the most effective parameters and to evaluate the results more efficiently, the full factor...
