The rapid advancement of information technology and its integration with the manufacturing technology increased the necessity of consistent and coherent data flow in the chain of Computer Aided Design (CAD)-Computer aided Manufacturing (CAM)-Computer Numerical Control (CNC). To achieve this, ISO 10303 standard (STEP), developed by ISO, is seen as a solution since STEP is independent of the environment on which design data, manufacturing data or machining data produced. In this thesis, efficiency of NC-code generation, with the inclusion of process planning data, from a STEP based CAD data is investigated. For the investigation purposes, software responsible for both building the STEP based CAD data and generating related NC-code automatically is developed. Using this software, several parts are designed; generated NC-codes are verified via CNC simulators and some test parts are produced. STEP AP224 based feature modeler, developed specifically for 2- axis rotational part design, includes; feature library, feature modeler employing SW2007 via API for visualization and preprocessor responsible for generation of STEP file in neutral format, called STEP Part 21. The NC-code generator includes; postprocessor responsible for STEP Part 21 interpretation, CNC machine tool and cutting tool database and preprocessor responsible for NC-code generation.

Design and Implementation of a Microprocessor Based Data Collection and Interpretation System with Onboard Graphical Interface
Göksügür, Gökhan; Güran, Hasan Cengiz; Department of Electrical and Electronics Engineering (2004)
This thesis reports the design and implementation of a microprocessor based interface unit of a navigation system. The interface unit is composed of a TFT display screen for graphical interface, a Controller Circuit for system control, a keypad interface for external data entrance to the system and a power interface circuit to provide interface between the battery of the navigation system and the Controller Circuit. This thesis reports high speed design of the Controller Circuit and generation of system fun...
An intelligent design approach trained by fabrication techniques
Sönmez, Ayça; Sorguç, Arzu; Department of Aerospace Engineering (2021-2-15)
The developments in recent technologies through Industry 4.0 lead to the integration of digital design and manufacturing processes. While manufacturing is becoming an essential input of the design, it is usually considered at the last stages of the design process. This misconception creates a gap between digital design and fabrication, resulting in fabricated outcome being different from initial design in the context of architectural tectonics. This thesis aims to provide a basis to bridge digital design an...
Kinematic design of mechanisms in a computer aided design environment
Demir, Eralp; Söylemez, Eres; Department of Mechanical Engineering (2005)
CADSYN (Computer Aided Design SYNthesis) is a visual, interactive computer program working under Computer Aided Design (CAD) enviroment, which accomplishes the synthesis and analysis of planar four-bar mechanisms. The synthesis tasks are motion generation, path generation and function generation. During synthesis, the dyadic approach is utilized which introduces vector pairs and complex number algebra to model the motion. The possible solutions can be limited for link dimensions, the center circle point cur...
Development of a step feature-based intelligent process planning system for prismatic parts
Amaitik, Saleh Muhammed; Kılıç, S. Engin; Department of Mechanical Engineering (2005)
Computer aided process planning (CAPP) is generally acknowledged as a significant activity to achieve Computer Integrated Manufacturing (CIM). In coping with the dynamic changes in the modern manufacturing environment, the awareness of developing integrated and intelligent CAPP systems has been raised in an attempt to generate more successful implementation of intelligent manufacturing systems. The main objective of this research work has been to develop an integrated intelligent process planning system tha...
Management of Service Function Chains in Programmable Data Plane
Yürekten, Özgür (2021-07-19)
The rapid development of information technologies necessitates the use of high-speed network technologies. Software defined networking and network function virtualization are critical technologies for high-bandwidth, dynamically managed and cost-effective networks. Offloading network functions to the data plane and management of network service function chain (SFC) using data plane programming improve network performance. In this study, the framework that enables the management of service function chains fr...
