Abstract


Fine Blanking has a well-established logistics network, providing on-time delivery to customers in Gauteng, Cape Town, Port Elizabeth, and Durban, which are the main industrial areas in South Africa[1].Fine blanking produces parts to closer tolerances and with a better surface finish than parts made using any other type of press working[2].To achieve this good blanking edge quality in fine-blanking, quite a large number of factors need to be considered simultaneously during the operation, such as blanking speed, processing material, product shape, lubrication and tool geometry[3]. Tolerances are to 0.0005 inch, with flatness to 0.001 inch per linear inch, allowing print tolerances out of the die[4].Virtual-prototyping software can simulate the full-motion behavior of many complex mechanical systems such as aircraft and automobiles[5]. By permitting designers to realistically, accurately and quantitatively prototype and test multiple intermediate models within virtual environment, Virtual Prototyping (VP), also known as Simulation-Based Design (SBD), has rapidly gained popularity and become a crucial part of most engineering design processes[6]. An environment is provided to implement virtual design reviews and enable the application of virtual prototyping methods[7].Fine blanking presses have three separate forces acting on the tool rather than the one or two of a normal press[8].Even though fine blanking has been used in industry for many years, only limited literature can be found which deals with the theoretical analysis of it[9]. In this paper Virtual-prototyping software will be used to simulate the motion of fine blanking die. In this respect, only limited efforts have been made thus far[10]..Effective virtual simulation of such a system requires a method of properly modeling a multi-domain system[11]. And ADAMS is the software I chose as the Virtual-prototyping software.. The commercial software ADAMS was used as a representative Automatic Dynamic Analysis of Mechanical System[12]..Mechanism configurations can be evaluated and the mechanical advantage will be calculated to select the better design[13]. Many people modeling and simulation of mechanical systems using MATLAB/Simulink and ADAMS[14]..The design of a machine can be done through the creation of virtual prototypes to model and simulate a wide range of machine characteristics[15]. A model based experimental investigative approach is presented in this dissertation[16].
