AB  - Developed procedures for tool path generation and application representing a CAD/CAM system is presented in this paper. This application allows automatic manufacturing technology design for parts with free form surfaces for loaded CAD models of part and work piece in STL file format. Generated tool path will represent optimal tool path in accordance with multi criteria optimization methods. Developed application allows usage without any user's expertise in the field of CAD/CAM systems. The optimal tool path for manufacturing will be generated, which will be performed in the shortest time possible, having appropriate surface precision and quality. Developed procedures which are implemented in this system are the result of years of research in this field at the Department of Production Engineering, Faculty of Mechanical Engineering, University of Belgrade, Serbia. Also, development of cutting force model and experimental determination of cutting force coefficients for tool/work piece geometry and material combination is described. Research was conducted for combination of aluminium work piece and ball end mill of HSSE steel. The application is developed as a GUI interface, in MATLAB software. Mentioned application allows generation of NC codes for rough and finish machining for the tools stored in the application database. According to the generated NC codes, several parts were manufactured using the horizontal working centre in order to verify developed procedures for tool path generation and optimization. Based on the conducted experiment, it was concluded that the machining was performed in allowed tolerances and cutting conditions which confirm the usability of the developed software application.

AB  - A new research was made in the field of free form surfaces machining at the Faculty of Mechanical Engineering in Belgrade, focused this time on rough machining of free form surfaces. This paper describes the development of this concept which is used when machining is not possible to be performed in one pass with ball end cutter. Based on a loaded CAD model of the workpiece and part, the developed system makes a machining simulation for ball end mill in one pass. In certain cases, when removing material in one pass is not possible, the system will provide two options for rough machining. The first option obtains an approximate shape of the free form surface for machining with end mill cutter in case the generated stock allowed parameter has an appropriate value for machining in one pass with a ball end cutter. The second option for rough machining with ball end mill performs two or more passes, maintaining the maximum allowed cut depth for the chosen tool in every single pass. After the final pass, the tool would be moved to next leading plane. The decision which option to choose out of these two depends heavily on the machining time generated by the machining simulation, which is supported by the developed system. By default, the system generates NC code for the strategy providing shortest possible machining time.

AB  - Development and usage of a software application representing a CAD/CAM system for automatic manufacturing technology design for parts with free form surfaces is presented. The system provides tool path generation for manufacturing input CAD models of a workpiece and a part, which will represent optimal tool path for multi criteria optimization methods. Based on already developed and implemented procedures for tool path generation and optimization, it allows usage without any user’s expertise in the field of CAD/CAM systems. Obtained tool path is generated based on the loaded part and workpiece CAD models according to multi criteria optimization method which is implemented in system. The optimal tool path for manufacturing will be generated, which will be performed in the shortest time possible, having appropriate surface precision and quality. Developed procedures which are implemented in this system are the result of years of research in this field at the Department of Production Engineering, Faculty of Mechanical Engineering, University of Belgrade, Serbia. For the purpose of developed cutting force model, cutting coefficients were experimentally determined for tool/workpiece geometry and material blend. Research was conducted for combination of aluminium workpiece and ball end mill of HSSE steel. The application software is developed in MATLAB as a GUI interface and it allows generation of control (G) codes for rough and finish machining for the tool stored in the application database. According to the generated control codes by this developed software, several parts were manufactured using the ILR HMC 500/40 machine tool in order to verify developed procedures for tool path generation and optimization. Based on the conducted experiment, it was concluded that the machining was performed in allowed tolerances and cutting conditions which confirm the usability of the developed software application.

AB  - With the upward trend in designer furniture production, this inevitably imposed the need for using CAD/CAE systems in its design and manufacturing. The reason for this is the increased competition in the market, necessitating new products to be released as soon as possible with a lower price tag. This in turn requires manufacturing of a zero prototype which should considerably correspond to the finished product later to be launched onto the market. A research was conducted to determine the applicability of a computer aided product design and calculation system, considering only tables of larger dimensions. The designer's original idea is firstly illustrated by a rough sketch or a CAD model of the table. The following step of the designing process is to analyze the stiffness of a given table, i.e. determining its stress and deformation state. Simultaneously, product manufacturing technology is also considered from a mechanical engineering point of view. Due to products’ specificity, they are usually made as a combination of tubular semi-finished products and sheet metal parts with thickness of 4-6mm. For selected table models, CAD models were generated using the Sheet Metal Module of the Autodesk Inventor computer software and Finite Elements Analysis (FEA) performed. Depending on the numbers obtained for stress and deformation state in the stress concentration zones, a modification of the shape is performed to fulfill the stiffness requirements. Static calculations were also carried out in order to determine the dimensions of the table base for the selected area of the worktop made of solid wood; usually oak. Experimental verification of acquired numerical results was conducted after manufacturing of a physical prototype of the table. The results obtained point to a conclusion that the application of CAD/CAE systems is justified in furniture design, particularly because it greatly reduces the time needed for designing good and quality products.

AB  - Based on several years of research at the Department of Production Engineering, Faculty of Mechanical engineering, University of Belgrade, Serbia, software for automatic tool path generation for parts with free form surfaces has been developed. Using this software, a tool path for machining o different parts with free form surfaces was generated. The main goal of the conducted research was to generate a tool path with minimal machining time whilst not compromising the machining quality. A multicriteria tool path optimization method was used, in particular the feed rate variation method, in order to obtain a control code (NC) that would allow machining with constant cutting force. Manufacturing of the parts was done at the Mechanical Engineering Faculty in Belgrade, using the ILR HMC 500140 tool system, according to generated control codes. During the manufacturing it was concluded that the machining of these parts was performed with constant cutting force. Geometrical measurements of manufactured parts were performed at the Department of Physics - University of Liverpool, UK using OGP Smartscope CNC 624 multisensor metrology system. The measurements of the manufactured parts were performed using two methods; contact (touch probe) and contactless (optical) whereby a point cloud of data was obtained. Using the MATLAB® software package, a program code was written that generates a map of the deviation based on the difference between the loaded point cloud and the CAD model. Finally, by analysing generated maps of deviation, it was concluded that the machining was performed within defined specifications. This demonstrated that the developed system is a useful for tool path generation for parts with free form surfaces.

AB  - Apart from having strong application in mechanical engineering, parts with free form surfaces  are a/so present  in  electrical  industry,  medicine,  appliance  and  consumer  goods  industry  etc.  Following  this increasing  interest,  the  research  team  of  the  Production  Engineering  Department  of  the  Faculty  of Mechanical Engineering Belgrade in Serbia, initiated series of studies in order to develop CAD/CAM system that will provide automatic manufacturing technology design for milling operations. The designed system is intended for automatic tool path generation based on loaded inputs (part/workpiece CAD model, workpiece material and surface roughness) and a database containing sets of values for available cutting tools and cutting coefficients for tool/workpiece material while considering geometry as  well. Manufacturing of the workpiece according to the generated tool path fulfills the requirements for minimizing machining time and production costs accordingly. The system generates machining parameters based on available data stored in the database, which is an integral part of the designed system. MATLAB® software package was used for developing this system, therefore no expert knowledge about CAD/CAM systems is necessary for its use. The machining of parts based on the developed optimization methods was carried out at the Faculty of Mechanical Engineering in Belgrade. Precise dimensional inspection of manufactured parts was performed at Department of Physics - University of Liverpool, UK using OGP Smartscope CNC 624 multisensor metrology system. Deviation maps  were created based on measurement data which demonstrate that the machining  was  performed  in  defined  specifications,  verifying  the  applicability  and  pertinence  of  the developed system.
