This document describes linking design and manufacturing on a PLM (Product Lifecycle Management) platform. Specifically, an automobile fuel tank cap was modeled in Creo Parametric. An injection mold was then developed for the part. The complete design data was integrated into Windchill PLM software for data and process management. The fuel tank cap design, mold design, and NC programs for manufacturing the mold were generated. The design data was then imported into Windchill where it could be accessed and reviewed by authorized users, including providing customer feedback. Integrating the design and manufacturing data onto a PLM platform allows for efficient management of the product data and process throughout the lifecycle.

Kameswari Sneha1 , Vinoth Rajah 2 , R. Ramesh3 1,3 Department of Mechanical Engineering, M.V.G.R College of Engineering, India 2 Adroitec Engineering Solutions Pvt. Limited, India Abstract: One of the means to quick and scalable manufacture in industrial environment is to employ software packages that allow for an “end-to-end design” and manufacturing. PLM or Product Lifecycle Management is used to realize these requirements. However little literature is available on this topic. In this work, a typical automotive fuel tank cap was modelled and an injection mould was developed for the part. The complete design data was then integrated into a commercial PLM software, for data and process management. It is expected that this paper which showcases design to manufacture linkage on a PLM platform will not only encourage industries/manufacturing units to plan for and employ this approach to their products but also add to the available information to the academic community on this highly practical/applied topic. Keywords: Creo Parametric, Windchill, Injection moulding, Modelling, Product Lifecycle Management (PLM). I. Introduction Plastics are now touching every aspect of our lives - from automobile parts to computers. One of the key methods of manufacture of plastics is the injection moulding process. More applicable to thermoplastics, e.g., ABS or Acrylonitrile Butadiene Styrene, Polyamide, Polyethylene, Polypropylene, Polystyrene, Polyvinyl Chloride (PVC) etc., [1] the major advantages presented by this process are manufacturing ease and speed. In this method, hot plastic is injected under pressure into a suitably designed die to form the required components upon cooling. On the design front, Computer-Aided-Design (CAD) has revolutionized the manufacturing process by allowing right from creating simple geometries to complex assemblies, [2] running functional simulations and thereby allowing for necessary optimization. Similarly Computer-Aided Manufacture (CAM) is well known for tool design and machine shop operations. We are now in a position to link CAD, CAM with the entire materials (inventory) and manufacture domain. This can led to an improved productivity via machine and work-force management, understanding material utilization to control scrap etc. Interestingly, one can integrate aspects related to machine utilization and maintenance, quality control etc. also in the above system which then would be called Product Lifecycle Management (PLM). PLM software assists manufacturing companies to manage the various aspects of the product by serving as a common platform to house and work with all information associated with a product throughout its life cycle - the key being design and manufacturing data [3]. On the other hand, Product Data Management (PDM) refers to another tool that is usually embedded into PLM software and is used to manage the “process and product history” [4]. Together, software of this nature lends the various parties (management, engineering and sales departments, and customers) to interact with the product during the course of its development, thereby bringing out improved quality and performance yet allowing for quick release of products with lower risk [5]. PLM is already used in automotive and other industries, however, unlike the standard CAD/CAM processes; both conceptual and illustrative literature on PLM is limited. The objective of this paper is to showcase some abilities and advantages of PLM software, by linking design and manufacture via a practical example: Automobile fuel tank cap. For this, the fuel tank cap was designed according to the required dimensions, and subsequently the design data was integrated into the PLM software for data and process management. II. Methodology 1.1 Study of the component The manufacturing design for a component is arrived after a systematic study of the following information: Specifications, appearance, quality and service. For this paper, the considered information was limited to the mechanical functionality of the cap i.e., closing and opening the fuel tank. 1.2 Modelling of the component Modelling, in simple words, is the process of generating a precise geometry for a component at hand so as to allow for its manufacture. In this work, the solid model of the component was modelled considering all the
Linking design and manufacturing on a PLM platform DOI: 10.9790/1684-12647278 www.iosrjournals.org 73 | Page required dimensions in Creo Parametric 3.0. For modelling of the component, different options like revolve, pattern, extrude, mirror, and round were performed. 1.3 Tool design Solid modelling of tool design was done by extracting the core and cavity in Creo Parametric 3.0. For the extraction of core and cavity, the parameters like shrinkage, tolerance, size of core and cavity have to be considered [6]. Here, these parameters were assumed. The amount of shrinkage to be considered is chosen by the type of material that is used for injection moulding. Thicker pieces shrink more than thin ones. Similarly, cores and cavities are sensitive to shrinkage and necessary tolerance must be provided to achieve the intended shapes and sizes of the components. The shape of core and cavity is considered according to the component. A flow chart for general process of tool design for a plastic component in Creo Parametric 3.0 is shown in the following Fig. 1. Figure 1 Process for tool design under manufacturing type and mold cavity sub-type 2.4 Tool manufacturing In this work, the tool manufacturing was done by considering all the required parameters and NC program was generated using Creo Parametric 3.0 [7]. Here NC programs for core and cavity were generated separately. A flow chart for general process of tool manufacturing for a plastic component in Creo Parametric 3.0 is shown in the following Fig. 2. Figure 2 Process for tool manufacturing under manufacturing type and NC assembly sub-type III. Results and Discussion 3.1 Design of the Fuel Cap The different details of the part and its design are shown in TABLE 1 and 2. Fuel tank cap was modelled and the result is shown in the following Fig. 3. Table 1 Part details of the component

Parting line helps to split up the mould into two half’s, i.e. core and cavity. For the extraction of core and cavity, the parameters like shrinkage, draft should also be considered. Here, all these parameters were assumed accordingly. Fig. 4 shows the extraction of core and cavity designed using Creo Parametric 3.0. In case the runner and gate design have to be considered, the diameter of the gate should be according to the type of the gate that is being chosen [8], whereas the location of the gate has to be selected by running the moldflow advisor analysis [9].

The end-program is highly accurate and needs no further processing before commencing production with a CNC machine. With the implementation of the above steps, the production is deemed complete. IV. Integration of fuel tank cap into the PLM software The CAD data of fuel tank cap was imported into Windchill 10.2, PLM software. The data is stored in the central repository [10] which acts like a back-up. Data loss and data-overwrite are both protected against. Such data, for example, may be used for accreditation/audit purposes in some cases. The general procedure for importing the design data into Windchill is shown in the following Fig. 8, whereas Fig. 9 shows the CAD part of fuel tank cap in Windchill. Figure 8 General procedure to import data into Windchill In case the design engineer makes any modifications to the existing data in Windchill, a new version of that design/document is saved back to the central repository, maintaining the same part name. Every time a new version for a document is saved, a short description can be provided to understand the changes made in that particular version. This helps in locating the versioned document and reduces the time spent. As a result one can differentiate how the document is evolved between versions.

Considering the guest member as a customer, the CAD data of the fuel tank cap was given access to the guest member for reviewing. This reviewing was done on basis of the requirement of the design of the component. Comments on the design can be given by the customer, which is shown in the following Fig.10. Figure 10 Note-up mentioned by the reviewer In this specific example (Fig. 10), as the customer was satisfied with the design of the component, this design can now be sent to further stage i.e. manufacturing. In case the customer needs any modifications, the required modifications are commented in a note-up and sent back. Then, product manager initiates a change request with the approver of the product. The approver investigates the comments mentioned by the customer and if modifications are necessary, a change notice is issued to the product designer. V. Conclusion In order to showcase the linkage of design and manufacture on the PLM software, an automobile fuel tank cap was modelled and further the NC programs were generated for manufacturing of the cap. Subsequently, the complete data on modelling and manufacturing was integrated into the PLM software, which enables a smooth flow data from CAD systems, provide access only to authorized users, automatic updates when data is modified, data re-use and easy change management, etc. At any point of time, if the customer requires modifications to the existing model, the modifications can be easily applied, without causing any time delays.
