In the case of a complex shaped helix bevel gear, the forging of complete gear tips is very difficult to achieve. In almost all cases, tooth profile is finished by cutting machine from simple shaped forged parts, therefore requiring considerable machining time and cost. However, there are many approaches to forging. Forging is mainly classified as hot and cold forging, and uses a single motion press. In the case of hot forging takeoff of products from die is difficult by the cooling shrinkage from die and accuracy of products is lower level than cold forging. In addition, in the case of cold forging, a complicated shape is difficult to achieve based on the lack of ductility of the materials. To realize a helix bevel gear using a single forging operation, we applied a tool heating system and three-axis forging press. The tool heating system is applied to prevent a temperature decrease in the material by contact between the tool and forging material during the forging process. Further, to optimize the forging direction and timing, we used a three-axis forging press. We confirmed good forging capability of this special forging process, as well as the high precision of the forged parts. Moreover, through the thermo-mechanical control of steel and the tool temperature, the forged parts showed good mechanical properties, such as high hardness.

This paper presents a simple and fast design and implementation for a soft robot arm. The proposed continuum arm has been built by a single self-bending contraction actuator (SBCA) with two-fingers soft gripper. Because of the valuable advantages of the pneumatic artificial muscle (PAM), this continuum arm provides a high degree of safety to individuals. The proposed soft robot arm has a bending behaviour of more 180° at 3.5 kg, while, its weight is 0.7 kg. Moreover, it is designed to assist the people by reducing the number of backbends and that leads to a decrease in the possibility of lower back pain.

In hot extrusion forging process, the use of  robot arm for transferring heavy billets can reduce downtime, improve  productivity, reduce worker fatigue and optimize the use of~energy and  manpower. To increase the stiffness of the robot and force the end-effector  move in directions parallel with the ground surface, two parallel links are  added to a standard serial manipulator. This modification of the structure  could make it a bit of challenge in the system modelling and controlling.  This paper addresses the inverse kinematics analysis that is the central  issue for developing autonomous control modes of the robot application.

Crankshafts, connecting rods, gears and forks are basic components made by the forging machine. According to statistics data, more than 60% of the automotive components in weight are produced by forging, more than 80% of which are manufactured by hot forging. With the development of the automobile industry and the increase of market competition, the forging production of automotive components is becoming more complex, sophisticated and efficient. Moreover, in order to reduce the labor costs and improve the efficiency, flexibility, automation and intelligence of the forging equipment and process, research and development of the hot forging intelligent production system will be inevitable. Based on this background, an intelligent production system of a typical hot forging for automotive components is introduced in this paper. It includes the intelligent high precision hot die forging press, intelligent transport devices, the intelligent control system, the operation management system and intelligent interfaces. Moreover, it also can be linked into the smart factory of industrial 4.0. This intelligent system has been developed and been used for the production of the third generation hub bearing, which has shown that the production efficiency is improved and the labor costs are reduced.

Abstract  This paper presents mechanical and electrical design, and implementation  process of industrial robot, 3-DoF type SCARA (selective compliment assembly robot arm),with two rotations and one translation used for welding applications.The design process also included the controller design which was based on PLC(programmable logic controller) as well as selection of mechanical and electrical components.The challenge was to use the available components in Iraq with reasonable costs. The robot mentioned is fully automated using programmable logic controller PLC(Zelio type SR3-B261BD),with 16inputs and 10 outputs. The PLC was implemented in FBD logic to obtain three different automatic motions with high efficiency withouterror,where the two links can stop in a certain points and link 3 bushed down for doing the task in a desired trajectory motion by programming the PLCcontroller. Keywords: DoF, FBD, PLC, SCARArobot.
