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.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

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
2. 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

Figure 3 Model of fuel tank cap
3.2 Design details of the mould
Silhouette curve, the curve passing through the extreme points of the component has to be selected
carefully, as this curve helps to select the parting line. 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].

For manufacturing of the tool, NC programs are generated for core and cavity. The parameters for core
and cavity should be considered separately. Therefore, the NC programs for both core and cavity were generated
separately. The operations considered for manufacturing of the component depends upon the CAD model. In
order to generate NC program for cavity, the operations shown in following Fig. 5 must be performed. The
parameters considered for these operations are shown in TABLE 3.

After assigning the above parameters for core and cavity, the NC programs for both were generated
separately. 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.

Figure 9 CAD part of fuel tank cap in Windchill
Apart from the team required for design and manufacturing of this component, a guest member was
added to the team, who can read the data without acquiring membership in the organization. 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.

This approach with PLM software could be of great help to the industries/manufacturing units as it has a high
potential to draw and manage the process, product, service data efficiently.
