Advanced Solution for Industrial Document Automation

Every Industries has so many departments and all the departments have various process from Product Enquiry to Dispatch. All these processes are governed by various documents that requires many levels of approval based on management hierarchy. Creating these many documents manually as hard copies and sending them for approval from one person to another person is time consuming and prone to errors. Also storing the hard copies for future reference or auditing purposes consumes more space with lot of risks over a period of time.
With SOLIDWORKS PDM Professional, these documents can be created as soft copies with single click and stored as digital data in a single secure location that shall be made available to right person at necessary times. The benefits of this one-time PDM implementation are many like High document Security, less process time, more organized data structure, more efficient communication between departments, Complete tracking of all projects, etc. All these can made possible with following procedure using SOLIDWORKS PDM.

Step 1: Creating required Industrial Document/Form

The various Industrial Document/Form like Sales Enquiry Form, Engineering Change Request form, New Product Development Form, etc. should be created individually in any Microsoft Office application like Excel or Word with appropriate Cells/Fields to provide necessary information regarding the process or project. These fields must be given with a field name which is later mapped with Custom Property (File->Info->Properties->Advanced Properties) of the same file. For automatic update of Fields/Cells in files added to PDM vault, the file must be enabled with macro for automatically updating all Fields. This file will be saved in a separate PDM Vault location along with other standard documents.

Step 2: Creating and Mapping the Variables

Variables are labels of data that must be provided in Document/Form through PDM database. Every variable will have different data specific to individual Document/Form added to the Vault. Individual Variables are created in PDM Administration Tool along with necessary attributes for mapping them with Document/Form data fields. Hence the values of the variables can be automatically updated in the Document/Form once the file is added to the vault. For mapping the variables with Microsoft office document Custom Properties, the block name of variables must be Custom Property and attribute name must be same as the Custom Property names of Document/Form. The vales for the variables can be set through,
• Values entered in Data Card of Document/Form
• Set Variable Action of Workflow state changing transitions

Step 3: Creating Data Card for Document/Form

Data card contains metadata (Properties) of files in PDM database. Data Cards are created in PDM Card Editor tool for different files, folders, items and templates with controls like text fields, list boxes, check boxes, tabs, etc. These controls can have special values like logged in user, created date, etc. Each of these controls are mapped with variables as required and their values are defined by the user while/after adding the file to PDM Vault. Data defined in the data card will be directly stored in the database as value of specific variable of that specific file. The same value will be mapped with the Custom property of Document/Form through the attributes created for each variable. The same value in file’s Custom Property will be updated in Fields/Cells mapped with them.

Step 4: Creating Template for Document/Form

Templates are created in New Template wizard with a data card that appears every time we execute a template command in vault. We can specify the Files (Document/Form) and Folder Structure that should be created automatically every time for a new project. The file name and folder name can be mapped with variables like Project No, Document number, etc. Templates also have user permission that lets only the appropriate user to create documents in the vault.


Step 5: Creating Workflow for Documents

Workflows are created in PDM Administration Tool as a replica of Industrial process or path through which the document moves inside an Organization. It has many States that depicts the stage of the project and Transitions that denoted the decisions of Stakeholders. In every State only the appropriate Stakeholder will have the permission to work on the file and when the file moves to another state, respective stakeholder will get notified about the file. In every Transition, actions like Increase revision number, Set Variable, conversion tasks, etc. can also be executed automatically. For example, If the value of variable Approved By is set to have updated to Username making the approval transition then the file will automatically have the signature of user who is approving the file.



The above procedure can be implemented for all process in every departments of an organization.

Design for Manufacturability using SolidWorks Tools

Design & Manufacturing Process Overview

The design stage is considered the most crucial component in the product lifecycle
process - the platform for the conception and development of new products.
Approximately 80 percent or more of the lifecycle costs of a product are determined
during the design stage. Companies are constantly fight the battle and pay the price
of miscommunication between design and manufacturing departments. Finding
errors and fixing defects during the design stage is the optimal way to achieve high
quality and cost-effective products.

Iterative Design Process

In the iterative approach to the design process, the designer needs to receive early
feedback from the manufacturing department to address any manufacturability
concerns before the design is frozen. This methodology is ideal however it is
generally only feasible in an environment where the manufacturing & design
departments are co-located. With the “Design anywhere - Make anywhere” practice
common throughout the world today, implementing iterative design is even more of
a challenge. In addition, because the iterative process involves manual reviews and
can be very time consuming, it is very difficult to catch and fix every concern in
complex part models.

Design for Manufacturability

Design for manufacturability (DFM) is a systematic approach for designers that
provides upstream manufacturability validation and identification of arear of a design
that is difficult, expensive, or impossible to machine by conventional methods.

SolidWorks DFMXpress: What is it?

DFMXpress combines practical process functionality with accuracy and ease of use. It
is perfect for the designer who needs to do manufacturability analysis but is not
necessarily a manufacturing expert and also permits designers to easily gain insight
into the cost-effective manufacturability of their designs by doing things properly the
first time.





Drill Rules

▪ Hole Depth to Diameter Ratio                                                 
▪ Hole Entry and Exit Surfaces
▪ Hole Intersecting Cavities
▪ Minimum % of Hole Area Inside Part

Mill Rules

▪ Fillets on Outside Edges
▪ Sharp Internal Corners
▪ Inaccessible Features
▪ Mill Tool Depth to Diameter Ratio

Turn Rules

▪ Minimum Corner Radius
▪ Minimum % Bore Relief

Sheet Metal

▪ Hole-Diameter-to-Thickness Ratio
▪ Simple Hole Spacing to Thickness Ratio
▪ Recommended Bend Radius

Injection Molding

▪ Minimum Wall Thickness – Maximum Wall
Thickness

Standard Hole Sizes 

▪ Standard Hole Sizes – Non-Standard Hole Sizes


Mold & Cast Part Check Tools:

 
Draft check

Undercut check
                                                                          

▪ You can use Undercut Analysis to find trapped areas in a model that cannot be
ejected from the mold.
▪ Set analysis parameters and color settings to identify and visualize areas with
insufficient draft on molded parts.

Thickness Analysis:

Thickness Analysis is used to identify the various thicknesses at each point on the
model, which helps to identify problematic areas that might be too thin or too thin in
any specific regions. This will be helpful when using thin-walled plastic parts.
Use Thickness Analysis to:
▪ Find out thick and thin regions of a part
▪ Determine portions of a part that are equal in thickness


Other DFM Tools Available in SOLIDWORKS for Part:

Geometry Analysis:

Geometry Analysis identifies model entities in a part that could create a problem in
other applications. These applications include finite element modelling or computer￾aided machining.
Geometry Analysis identifies the following entities:
▪ Sliver faces
▪ Small faces
▪ Short edges
▪ Knife (sharp) edges and vertices
▪ Discontinuous edges and faces
The results can be graphically analyzed with the Geometry Analysis Property
Manager that appears after the analysis is complete.



Other DFM Tools Available in SOLIDWORKS for Assembly:

Interference Detection:

One of the key evaluation tools in an assembly is Interference Detection. This shows
any possible interference between selected components so that we can modify the
parts and prevent issues in manufacturing.



Clearance Verification:

When working in an assembly that requires specific clearances, you can estimate and
verify the gap between selected components using the SOLIDWORKS Clearance
Verification Tool




Hole Alignment:

Ensuring hole alignment between various components in your assembly designs, prior
release to manufacturing, it reduce the product development process and make your
design ready for manufacturing in the first time.


Benefits of Design for Manufacturability Tools in SolidWorks:

• DFM tools help Engineers and Designers design less costly and better quality
products, faster
• Helps catch and fix problems related to manufacturability early in the design,
where it is much cheaper and faster to implement corrective action
• DFM tools dramatically improve communication between design and
manufacturing
• DFM Tools help capture design and manufacturing best practices and allow both
designers and manufacturers to become better at their jobs.

Conclusion:

Design flaws are often “easy to identify” but “difficult to solve” during 
downstream stages like manufacturing via simple rules-based checks, DFM allows
designers to optimize the entire design through manufacturing process by predicting
manufacturing issues during the design stage. In addition to saving countless back
and forth design review steps, DFM assists in creating a product design that is
compatible with the desired manufacturing process, in accordance with desired quality
standards, and cost-effective to manufacture.
Stay safe and productive everyone!

What is Pores Medium & How to Simulate it in SOLIDWORKS Flow Simulation?

Material which contain Pores are called Porous material, the weight of the porous material is less when compared to the solid material. The porosity of the material is defined by the Porous size the is formed in the material, there are different techniques for manufacturing these type of material depending on the size of the porous void that to be formed.
There are wide range of applications like catalysis, chemical separations, tissue engineering and exhaust manifold. In the exhaust manifold the harm full chemicals are removed by using porous material.
There are different types of Porous material according to direction of flow

1. Isotropic
2. Non Isotropic(Unidirectional, Axisymmetric, Orthotropic)
There will be change in the pressure, velocity and direction of flow changes according to the porous medium, by using Solidworks flow simulation can simulate the flow.

Steps for creating the Porous medium in Flow study:


1. Create the wizard by defining the Flow type, units, types of Fluid.

2. If the porous is not showing in the tree then Right click on project(1) options appear as shown in the Fig:1, click customize tree

3. The options appear as shown in Fig:2, click on the Porous Medium to get activated.


Fig 1
Fig 2
  

4. An exhaust manifold with porous medium and the inlet and out let manifolds as shown below:


5. Defining the porous material to individual domains, one part as unidirectional are shown below:


6. Defining  isotropic for the other domain as shown below:


7. The Fig:3 shows how the porous medium is defined in the study 

Fig 3


By running the simulation we can obtain the inlet and outlet velocity, pressure drop, due to porous medium, depending on the size of the porous and the type of the porous there will be change in the velocity, pressure
drop, these can be captured prier using SolidWorks Flow simulation.
