Challenges in the Automotive JIS/JIT Production of Steering Wheels Involving Traceability

The purpose of this article is to present the new challenges faced by the automotive industry and specifically by the steering wheel producers in terms of product design changes, process changes and the solution to solve them, the concept of TTM - Total Traceability Management. The article presents the traceability solution as a proved solution for managing JIS (Just in Sequency) & JIT (Just in Time) manufacturing concepts in terms of customer demand sequence attainment, process sequence attainment, and technical test verifications. The research is based on case studies deployed in production facilities, in the companies TRW and Key Safety Systems. Both entities are steering wheel producers with JIS&JIT conditioned production systems and are also using latest technology in synchronizing the traceability communication with various cars producers (Porsche, BMW, Daimler, etc.). This concept of manufacturing and delivery of the products to the famous automotive companies is crucial for the supplier including the base of business, because the entire work in this domain is completely automatic by robots. That means: all the final products (cars end others), including the components from different suppliers, also the technology of assembling, it need to be adapted in order to be performed by robots. The components as steering wheels, and many others, arrive at the assembling line at OEMs (Original Equipment Manufacturing) facilities and the robots work on directly the buffers with these components in order to ensure the continuous assembling process in the condition of total flexibility and without errors.

Development and Implementation of a Mini CNC Milling Machine

The development of mechanical processing machines with integrated CNC systems allows the manufacturing industry to produce complex products quickly with high quality. CNC has become a main course for mechanical students in technical and vocational universities. CNC machine training is required to enhance student’s skills to learning in design and manufacturing technology. However, the cost to buy a CNC machine is not cheap. In a developing country like Vietnam, along with the limited budget of most universities, this is an obstacle for students to have the opportunity to use CNC machines. To help students have a teaching aid in learning, improve practice capacity. The article proposes an alternative to design and manufacture a simple, inexpensive milling machine with all the required functions. The CAD models design of the machine model structure were done using Solidwork and NX software. Most of the machine’s parts are manufactured and assembled in the Faculty of Engineering Mechanics and Automation laboratory of Engineering and Technology, Vietnam National University Hanoi. The study’s main objective is to propose a process for designing and manufacturing a mini vertical 3-axis CNC milling machine with low cost but full features similar to an industrial CNC machine. The machine model introduced in the article can be used as a teaching aid, improving practical capacity for students of machine building

Simulation of Production Processes in Combination with Traceability

The TTM (Total Traceability Management) is becoming a mandatory process requested by all OEMs (Original Equipment Manufacturing) as a system to be deployed by the relevant suppliers. Process parameters from the machines are gathered by the TTM software and based on a defined algorithm the product is receiving new statuses, as physical and software characteristics. Given the high complexity of the current process flows, the highly automated lines and cells, the increased amount of process parameters, the necessity of synchronizing various production steps, it is needed that a simulation process to be done in advance of the full process deployment. The paper work reviews both the mathematical apparatus that underlies the simulation, and one of the various available simulation programs in academia. It is used one of the most usual software for simulation SIMQuick which is based on statistical methodologies. SIMQuick performs a virtual simulation of the process being used in various areas of activity including production in automotive, automation, supply chain processes and services, providing the valuable data for the behavior of the process and providing the premises for layout, flows, and resources improvements. The supply chain software ERP requirements with TTM technical inputs and outputs are the data pillars for the simulation which are presented as a result of the research.
