This research will investigate the problem of path planning for a 5 axis articulated robot, operating in an environment with obstacles whose boundaries are enveloped by a spherical shape. The path planning approach has been developed in the robot joint space and consists of five phases : The first phase is using Bezier, Hermit, B - spline and NURBS curve techniques considering their control points weight not constant. The second phase is to generate a sufficient number of intermediate points in Cartesian space along those curves. The third phase converts the coordinate of the generated intermediate points from its Cartesian space into joint space and move the robot gripper along the generated path. The fourth phase screens the generated four Bezier, Hermite, B - Spline and NURBS paths in order to choose the best one. The fifth phase is developing the chosen path by using proposed algorithm to improve the selected path.Both forward and inverse kinematics solutions for the robot links using Denavite - Hartenberg representation are important step to determine the manipulator's joint angles and Cartesian coordinates, that assists generating the required path which has been derived in this work.Matlab program has been used as an assistant program to analyze, sketch and implement the algorithms of forward kinematics, inverse kinematics and path planning.This work will not be limited to theoretical studies or simulations, experiments have been run with various tests, on "educational robot" Lab - Volt R5150 to assess which path is the better ability in avoiding the obstacles. The method applies to robots in a fixed and known environment. A number of experiments have been carried out to test the ability of the robot arm to reach its goal without collision It’s found that Bezier curve was the chosen path because it was the better obstacle avoidance and shorter path.

Abstract: The aim of this work is to design and manufacturing a multistage (three stages) deep drawing dies to produce cylindrical and hexagonal cups of (43,33.1,26.8)mm diagonal diameter through two methods. The first method by drawing the hexagonal cups directly by using hexagonal orifice die from a flat sheet (blank) of (80mm) diameter and (0.7) mm sheet thickness for (1006 - AISI) hot rolling low carbon steel material.The second method by redrawing a cylindrical cups of (43,33.1,26.8) mm outer diameter (produced previously by a cylindrical orifice die) in to hexagonal orifice die which transform (convert) these cylindrical cups into hexagonal cups of (43,33.1,26.8)mm diagonal diameter.For all stages of drawing hexagonal cups, wall corner radius of die (0.7, 4)mm, with punch and die profile radius of (4 and 8) mm and drawing speed of (50, 200, 500) mm/min were used to study the effect of these parameter on drawing forces, cup wall thickness, strain distribution over the cup wall and surface defect of the cup wall.A commercially finite element soft ware (ANSYS 11.0)was used to perform the numerical simulation for cylindrical and hexagonal cups in three stages of drawing process. A comparison between theoretical (simulation) and experimental results lie within average of (15 - 20%), and the agreement is good in the first stage.The results shown that excessive metal flow ,maximum thinning of cup wall and maximum strain occurred at corner radius of (0.7) mm and at drawing speed of (500mm/min )for hexagonal cup produced directly from flat sheet.The results shown that the best thickness distribution and strain distribution over the cup wall, better cup wall surface (less surface defects) and lowest drawing force was with percentage (63.8%,45.4%,74.1%) respectively occurred when transform (converting) the cylindrical cup into hexagonal cup with wall corner radius of die (Rc= 4)mm in three stages.

Two CAD models has been designed by using Solid Work 2013 software, then G - code have been generated and simulated by using Surfcam V5 software with (Fanuc post processing). AL7075 - T6 alloy has been used for its high machinability, dry machining (no coolant) has been done on 3 - axes milling machine (C - tek) available in the University of Technology Training and Workshop Center.Feeds, speeds and other machining parameters (axial and redial depth of cut) have been selected according to machining handbooks recommendations. Machining of workpieces has been accomplished by using two techniques (two types of tool - path), first one was conventional tool - path machining (contour parallel tool - path), and the second was by using TRUEMILL technique (true engagement controlled tool - path) by Surfcam V5. Thirty experiment have been designed, four of them have been failed, ten have been accomplished and the others neglected for reasonable causes as it will be discussed. Finally a comparison between the two techniques has been made focusing on machining time, material removal rate, cutting temperature and surface roughness. The results confirm that TEA control leads to reduce machining time, we have a time reduction in about (80%) for contour machining and (57%) for pocket machining. Cutting heat was under control though the feeds and the axial depths of cut went higher, also by controlling tool engagement angle we skipped the cause of failure of some experiment in conventional tool - path machining. Surface roughness was not that affected by controlling tool engagement angle, the minimum surface roughness in hand is (0.43 µm), it is higher than the best result of a previous work for the same material by 50%.

Abstract: Superplastic properties and microstructure evolution of commercial AZ31B magnesium alloy processed by two different severe plastic deformation methods Equal Channel Angular Pressing (ECAP) and Equal Channel Angular Rolling) ECAR) were studied. Samples were tested in tension at temperature of 623 K and strain rate ranging from 2.4×10 - 4 1×10 - 2 s - 1. ECAP die with 10 ×10 mm cross section channel, oblique angle of ?=90° and ?=13° was designed to refine the alloy microstructure at temperature of 473 K using route BC. Application of ECAP showed a remarkable grain refinement for AZ31B Mg alloy from 14.1 to 2.1?m after three ECAP passes. Maximum superplastic elongation of 261% was achieved at 623 K and strain rate of 2.45×10 - 4 s - 1. The measured strain rate sensitivity was m = 0.33 demonstrating that viscous glide control creep was the dominant deformation mechanism. In most investigation used ECAR process, the die temperature was set to room temperature, in order to avoid cracking intermediate annealing was used for AZ31B Mg alloy which has poor formability at room temperature. This is caused by a lack of active slip systems, especially in the <c+a> direction. However, in this study a special isothermal ECAR die capable of operating without intermediate annealing was used to process AZ31B Mg alloy. The ECAR was carried out at 623 K using a die of ?115 ° channel angle and without rotation. Processing by ECAR showed less effect on the microstructure refinement where the grain size was reduced from 10?m to 4.2?m after six ECAR passes. ECAR increases the yield and ultimate stress and decreases the elongation corresponding to increasing the number of ECAR passes, the as - received material exhibits large amount of superplastic elongation compared to ECAR processed specimens. Therefore superplastic behavior of the AZ31B magnesium alloy was evaluated at temperatures 623 K and strain rate ranging from 7.8×10 - 4 s - 1? 1×10 - 2 s - 1. The test showed that maximum elongation of 367% can be achieved at 623 K and strain rate of 7.8×10 - 4 s - 1. The strain rate sensitivity (m) was evaluated by two different methods, uniaxial tensile test on the basis of the true stress true strain curve and by strain - rate jump test. The results show small differences between the two method) m = 0.42 - 0.45), which demonstrate that the grain boundary sliding (GBS) is the dominant deformation mechanism during superplastic test Keywords : Superplasticity.

Abstract: تعد عملية تشكيل الصفائح التزايدية تقنية حديثة نسبيا لتشكيل الصفائح المعدنية والتي توفر امكانية تصنيع اجزاء معقدة الشكل وذلك باستخدام مكائن التفريز المبرمجة (CNC milling machines) بدون الحاجة الى قوالب خاصة لكل منتج والتي تتطلب وقتا طويلا للتصنيع مقارنة مع | Incremental Sheet Metal Forming (ISMF) is a modern sheet metal forming technology which offers the possibility of manufacturing 3D complex parts of thin sheet metals using the CNC milling machine. The surface quality is a very important aspect in any manufacturing process. Therefore, this study focuses on the surface quality of parts produced by single point incremental forming (SPIF) process. As a consequence, the objective of this study is to control the surface roughness by studying five forming factors, namely; (tool diameter, step size, tool shape, rotational speed and slope angle).In order to evaluate the surface quality, practical experiments for forming pyramid like shapes have been carried out on sheets of aluminum AA1050 with thickness 0.9 mm. As a result, two Adaptive Neuro - Fuzzy Inference systems (ANFISs) are conducted for predicting the surface roughness. The first system depends on the five forming factors as a direct contact estimation method while the second system utilizes contactless parameters (average gray level, standard deviation and mean frequency) that are extracted from the products images using a vision system as a contactless prediction method. A third model is developed using Sugeno Fuzzy Inference System (SFIS) for the evaluation of forming factors by which the surface roughness for a certain slope angle is obtained.Both quantitative and qualitative assessments have been used to explore the effects of the five forming factors on surface quality of parts produced by SPIF process. The ANOVA and MEP results show that the incremental step size and the forming tool shape are the most important factors affecting the surface roughness. These two factors are directly and inversely proportional to the surface roughness respectively. The maximum and minimum surface roughness, which is achieved from all the 24 experiments is (Ra = 4.3 & Ra = 0.18 µm) respectively. As a result, a surface with roughness smaller than the initial roughness of the sheet (0.27 µm) has been obtained. The qualitative assessment reveals that the surface roughness tends to increase towards the part deep.It can be concluded that the image based estimation of roughness using ANFIS is superior in terms of prediction accuracy. This vision system can achieve (97.856%) testing prediction accuracy compared to (85.799%) that is reached by the direct contact estimation of roughness. Conclusions also show that the vision system is capable of predicting the surface roughness of a hyperboloid part as a non - linear shape with prediction deviation (14.411%), thus enabling to evaluate the surface quality of complex parts that cannot be measured by the stylus. It can also be concluded that the SFIS is a successful approach for estimating the forming factors by which the surface roughness for a particular slope angle is obtained.

This method provides the designer with many powerful tools to add details only where necessary on the CAD modeling, create non - rectangular topology of the surface, easily edit complex freeform models, and besides maintaining NURBS (non - uniform rational B - splines) compatibility of the model.ThisThesisuses T - spline for surface modeling and compare it with NURBS modeling to get the best modeling points between the two methods. The comparison will be through surface analysis and manufacturing process.ThisThesisincludes design of two types of models : convex model (bicycle seat) and concave model (longitudinal section of the bottle) for each T - spline surface and NURBS surface using Rhinoceros 5.0 software which has been transformed to UG - NX8.5 software to get the machining process simulation and G - code programs for the models.

Abstract: التشكيل التزايدي للصفائح المعدنية هو عملية مرنة للغاية ومتعددة الاستعمالات للتصنيع السريع لاجزاء الصفائح المعدنيه المعقدة حيث تمتلك امكانية التكيف بامتياز مع انظمة التحكم الرقمي بالحاسوب (مكائن التفريز المبرمج CNC) من خلال السيطرة المباشرة على بيانات CAD | Incremental sheet forming (ISMF) is a highly versatile and flexible process for rapid manufacturing of complex sheet metal parts. It has excellent adaptability to computer numerical control (CNC) systems through direct control of CAD data, minimizing the use of specialized tooling and presses. A sheet of metal is formed by a progression of localized plastic deformation using simple forming tool controlled by a CNC machine - tool. The aim of the presented thesis is to investigate the feasibility of incrementally forming of 3D complex shape (like automotive heat shield shape) and the solar cooker shape by Single Point Incremental Forming process without using a dedicated die depending on different tool paths. Six different forming tool paths (unidirectional ZLVTP, bidirectional ZLVTP, FPRTP, ZGZTP, BSLTP and HSLTP) were generated byUnigraphics - NX8 (UGS - NX8) programing system and applied to realize solar cooker shape and automotive heat shield shape. The feasibility investigation and development of automotive heat shield shape is based on three control factors are tool path type, forming tool head shape and the Z - increment (vertical pitch). For each of these factors, levels were tested. The tool head shape and vertical pitch contain their both on two levels while the tool path type on six levels. Hence, 24 experiments applied to realize automotive heat shield shape based on a full factorial design of experiments, and 6 experiments applied to realize solar cooker shape. Hybrid tool paths are tested to explore the applicability these paths in ISMF process. This thesis discussed the impact of tool paths types and other control factors (tool shape and vertical pitch) on the three different quality characteristic namely geometrical accuracy, thickness variation and forming time. The significant of the control factors are explored using two statistical methods are analysis of variance ANOVA and main effect plot. All experiments were carried out on sheets of Aluminum Alloy (AL1070) with thickness 1.5 mm by using 3axis CNC machine. The CNC machine and dial gauge are used to measure dimensional accuracy and final thickness of formed parts respectively. Depending on the results of this work, Helical - Streamline tool path (HSLTP) and follow periphery tool path (FPRTP) are achieved higher geometrical accuracy when forming the solar cooker shape and the automotive heat shield shape respectively. On the other hand, Z Level profile tool path (ZLVTP) is the best tool path to achieve homogeneous thickness distribution and minimum forming time of formed parts. Hybrid tool paths are undesirable in incremental sheet metal forming. The ANOVA results show that all control factors have influence on the accuracy, especially the tool path type. The tool shape and vertical pitch have no influence on the thickness of the formed parts. But, the vertical pitch has major effects on the forming time and accuracy. In contrast, the tool path shape has a great influence on the process implementation.

Abstract: ان الصفائح المثقوبة تستخدم عالميا في تصنيع الھياكل في التطبيقات الميكانيكية والانشاءات كمثال على ذلك ھياكل الطائرات والتراكيب الطبية ووصلات الربط الخ. ومن المعروف جيدا ان استعمال الثقوب في الھياكل المجھدة تولد اجھادا موقعيا عاليا في منطقة من الثقب تعرف بم | The plates with holes are used in cosmopolitan for manufacturing structures in mechanical and civil engineering applications like aircrafts, medical structures, joint connection applications etc. It is well known that utilizing holes in stressed structures produces highly localized stresses at area of the holes known as the stress concentration area,which leads to reduce the mechanical strength of the structures.The main objective of this study is to investigate the effect of three parameters on the stress concentration factor in plate with two holes having different size holes and subjected to uniaxial tension. The three parameters include firstly, the location of holes when oriented with respect to axis of loading, parallel, transverse and inclined with line of uniaxial tension load at different angles. Secondly, the aspect ratio for the hole size (large to small radius).The last parameter effect is the distance between two holes.Numerical simulation using finite element method for two - dimensional model is developed to determine the maximum value of Von Mises stress with commercial software package ANSYS V.11.The experimental photoelastic technique is carried out on fabricated polycarbonate model loaded in one direction. From the analysis of the results, it is found that the maximum stress concentration factor is at the point tangent to the edge of the hole. The comparison between the finite element method and experimental photoelastic technique results showed the stress concentration factor, which obtained experimentally and with finite element method are congruent, since the maximum variation between the two results is about 7.03% As well as the highest and lowest value of the stress concentration factor equal to 3.1973, 2.0640 at value of angle 60°, 90° respectively.It is recommended from the above conclusions that manipulating the three parameters which effect the stress concentration factor are namely, holes position, size, and distance between two holes on the plate that used in the application will play essential role to reduce the value of stress concentration factor which subsequently crucially minimize or avoid fast failure. This can be translated into saving precious lives preventing money wastage due to structures damage ending into catastrophe.

Unfortunately they still cannot ensure the quality of machined products. The trend towards automation in machining has been driven by the need to maintain high product quality with improving production rate, these improvements can be possible by monitoring and control of machining process. In this research a vision based monitoringsystem was introduced for the on - line direct automated measurement of the cutting tool flank wear width based on a new algorithm on the basis of canny edge detection and morphological operations for the captured images.Twelve specimens were prepared using STARCHIP CNC turning with four cutting speeds (57,98,110 and 125 m/min) and three depths of cut (0.5,1 and 2 mm) and constant feed of (0.04 mm/rev). Maximum and minimum absolute error and error percentage in the maximum flank wear width was (0.058,0.002 mm) (9.7,0.54 %) respectively. The results show the effectiveness of the proposed method in the monitoring of the tool condition.Also, Vision based monitoring system was proposed for the measurement of tool nose wear which have direct interaction with the workpiece during machining. Measurement operation is done by comparing reference and worn tool images; the algorithm is composed of image preprocessing, Otsu thresholding, conforming method for the exact alignment between the two images and image subtraction is performed in order to detect the nose wear area. Morphological opening by reconstruction was used to remove isolated foreground pixels result in due to the quantization errors. The maximum and minimum error percentage in tool nose wear area (6.72,0.48 %) respectively; the experimental results show that nose wear occurs after the flank wear exceeded its maximum standard limit in roughing operations Keywords : tool wear, flank wear, nose wear image processing, automated visual inspection, tool condition monitoring.
