The purpose of study BIW process includes the following: The special focus on the structure of a body BIW enables you to find the logic and flow of body panels, and the relationships between them. The analyzing of body is made up of several hundreds of stamped components which are joined together by spot welding with welding gun for understanding of welding points and allocate them to welding operations.

Study of cycle time diagrams, for check reach ability and optimizing it. Cycle time is estimating the required working time for each station. You create your concept design based on process study Now you can use of process study for defining the design criteria and finding or verifying the concepts. The welding fixture design is created with the following steps: The clamping plans for accurate positioning of components, while the components are aligned to a suitable plane for welding they are designed in the carline plane as in BIW.

Design of the weld fixture is unit based on clamping plan, therefore there are a number of fixture unit types used in the welding fixtures for the purpose of each unit and due to the complexity and shape of the component geometry, the choice of elements as well as configuration of each unit tends to change from case to case.

The check of weld accessibility and spot weld for unrestricted access to each weld point, before and after the fixture design, the accessibility of the weld guns to all the spot points can be simulated and studied thoroughly to avoid guns colliding with other fixture elements. The 3D Modeling becomes the basic for following item: Create 3D Modeling of the weld fixture for visualizing the entire fixture in a three-dimensional environment.

The 3D CAD Model of weld fixture unit enables you to make CAD Model of clamp location plan for ensuring that plan problems and waste are discovered before your fixture drawing to send for manufacturing. By 3D Modeling of weld fixture, you can quickly prepare manufacturing drawings. For design welding fixture, trying to understand processes is essential. It is starting with process logic and flow, and defines the relationships between operations.

The process study is a solution that to help you quickly define and evaluate process to arrive at the best plan for designing your fixture. The result is process study containing a full description of how a product is assembled, manufactured and increases your profitability by improving critical success factors in your fixture design. The process study allows designer to leverage and optimize existing resources and to better integrate the designing process from beginning to end can not only help designer create fixture faster, but you can also begin design earlier in the overall cycle or even start later, in order to accommodate unanticipated changes.

The Assembly Process studying allows evaluating alternatives, coordinating resources, optimizing throughput, plan for multiple variants, implement changes and estimate costs and cycle times, from the very early stages of concept planning through process. Studying, Analyzing and Managing Manufacturing Processes enables you to collaboratively plan and analyzing manufacturing processes for your fixture.

You can create optimal design and accommodate multiple plan variations, quicker and faster than ever before. Process study provides a collaborative environment for planning designing processes. A broad range of applications enable you to define and verify body assembly sequences, create clamping plan layout, define the required time for each operation, verify plan performance, perform plan balancing and analyze of spot welding and guns.

The body-in-white Manufacturing Process includes: Automotive body assembly Cycle time diagrams Automotive body assembly The major process of an automotive body is electric resistance welding. The body of automotive is made up of several hundreds of stamped components which are joined together by spot welding process.

Overall quality of the car body BIW and quality of the sub assemblies, apart from quality of each stamped part, depends remarkably on quality of the welded joint. You should study of part joining, welding operations such as spot-welding and define welding points and allocate them to welding operations.

The study of welding process can be classified as follow: The number of welding spot The position and volume number of welding spot The type of welding gun The material and sheet metal thickness for setting of welding condition Cycle time diagrams The cycle time is estimating the required working time of each station. Cycle time study is based on the information such as: Part loading.


Inter-Consulting Europe (UK) Limited has the following contracts available:

It is used to design, simulate, analyze, and manufacture products in a variety of industries including aerospace, automotive, consumer goods, and industrial machinery, just to name a few. It addresses all manufacturing organizations, from OEMs through their supply chains, to small independent producers. CATIA is in the plane that just flew over, the car that just went silently by, the phone you just answered, and the bottle of water that you just finished. When you learn to use CATIA you also learn to work with leading-edge technology and play an important role in innovation. You will know how to design from scratch or reuse the working knowledge available from previous designs. Position yourself for the employment you want.

Learn how and when to remove this template message Body in white, partially outfitted to highlight the safety systems fitted to the vehicle. The name derives from manufacturing practices before steel unibody monocoques — when automobile bodies were made by outside firms on a separate chassis with an engine, suspension, and fenders attached. The manufacturers built or purchased wooden bodies with thin, non-structural metal sheets on the outside to bolt onto the frame. The bodies were painted white prior to the final color. This could also refer to when car bodywork would be made of timber - all timber products, furniture etc. In car design, the body in white phase refers to the phase in which the final contours of the car body are worked out, in preparation for ordering of the expensive production stamping die.
