After commercially releasing Mechanical design software CEAD last year, CADVision has announced a new major version with CEAD 2015 with new enhancements. This is bound to improve the process of “Phrasing” and “Synthesizing” that aids design engineers achieve their design goals quicker.

CEAD, a software that integrates CAD/CAE/math tools for conceptual design, is empowered with new features like curves, creation of linear and circular patterns, supporting DXF files, and a lot more.

It’s a constant endeavor of CADVision to create a software that can reduce overall product design cycle time. Manufacturing giant like Terex, with the help of CEAD, achieved 90% reduction with rave reviews.

“This new version addresses requests from the industry making it friendlier to new product design in mechanical, automotive and aerospace industries” said Siddharth Reddy, Director of CADVision Engineers. “We have come up with enhancements and new features that makes the design engineer’s life much more comfortable.”

New Features of CEAD 2015:

• CEAD now supports curves: CEAD enables the creation of curves and is simply achieved through a set of points. Geometrical constraints are supported on these control points.
• Multi-Level Groups is now supported.
• Local groups are now supported: Group files can now be saved locally in the main design file.
• Linear and circular patterns can be created.
• DXF files can be imported to CEAD and design files from CEAD can be exported as DXF files.
• Text alignment: Equations and texts can be aligned both to the left margin and vertically.
• Dynamic Simulation: The simulation of CEAD is much more evolved with “step size,” and “current value.” With the addition of new functions, “deltatime()”, and “delta(variable name)”, the change in time and change in the variable value per step is seen.

With its fast gaining popularity among the manufacturing companies and its German language interface, CEAD is one software solution to look at for product design and development. It will improve efficiency, reduce design cycle time and encourage innovation.

Terex India R&D Center (TIRC) was established in December 2008 by a mandate from Terex Corporation with the objective of providing engineering support to all segment engineering teams across the globe including products manufactured indigenously to suit the Indian market. The team that is based out of Bangalore supports more than 25 engineering centers of Terex across various geographies – USA, UK, Europe and Asia Pacific.

The Business Challenge
The Terex engineering team was working on an ambitious project of designing & building a family of wheeled and tracked excavators for the international market. The new equipment had to match features of the other globally made machines and also exceed quality and match customer price expectations as compared to the market leader in this segment. The team was challenged to get the machine ready within a very short duration. This was going to be a true test of delivering advanced analytical capability by the team under a restrictive timeline.

The Engineering Challenge
One of the critical tasks set out for TIRC was to create designs from scratch of theentire workgroup assembly within a span of three months. Workgroup consists of boom, dipper, bucketand related links that are primarily used to dig earth (see image)

Workgroup is specified by a range diagram that defines horizontal reach on ground (A-A’), digging depth (B, B’ &C), dumping height (E) and also the forces it can generate at the bucket tip to dig earth.

Generating the geometry that fits the specification is not just tedious but very iterative. The task is complicated as the geometry has not only to fit the required range specifications, but has to take into account manufacturing constraints, working clearances, forces and moments, section sizes for strength and transportation limits. Often Engineers with specialized knowledge are employed to work on the geometry and at times it takes months to arrive at an optimized solution and TIRC wanted the team to invest time smartly and get appropriate results in an efficient manner.

Traditional Approach
Traditionally, engineers would create a 2D geometry using existing commercial CAD tools. Working clearances are then checked in 3D CAD models created based on 2D geometry. Then using either specialized software programs or excel do the first-cut force and strength calculations. This would go on iteratively until a satisfactory solution is found for more detailed design, followed by FEA optimization and manufacturing drawings. Synthesis of appropriate geometry (red box below) takes up almost 60% of the overall effort in the design exercise and at times takes months to get it right. Given the complexity of the process with different tools engineers settle for the best compromise time can buy and the designs are iterated over newer product versions. Terex, like any other equipment manufacturer wanted to get it right the first time.

Terex India R&D Center (TIRC) Approach
Keeping all of the above in mind, TIRC began a grounds-up approach to developing the workgroup geometry for the machine using a new software tool called CEAD (rhyming with ‘seed’). CEAD is an integrated product design environment enabling parametric geometry creation and mathematical calculation in the same worksheet.

As depicted in Figure 1, CEAD enables concurrent inter-play of mathematically definable facets of the design, be it manufacturing constraint, functional target or performance parameter, from any domain of physics in the synthesis of geometry.

Key to Terex India R&D Center (TIRC) approach lay in

• Concurrent definition of all positions of the workgroup, manufacturing constraints, force calculations and working clearances in a single CEAD work sheet.
• Defining positions, range dimensions, working clearances, forces, cylinder pressures, section moduli as variables that drive the geometry and vice-versa through mathematical functions.

Then using built-in “Optimize”, “Change” and “Simulate” functions of the software a geometry that best fits the laid out constraints was found.

The final outcome
This process innovation thus moved much of the engineering constraint analysis ahead of 3D prototype creation, resulting to fewer redesigns to the 3D geometry and therefore more streamlined integrated product development. Significantly, project cycle time was reduced by 90% and it took just two weeks from start to getting an acceptable geometry that included couple of additional iterations driven by product marketing.

The core innovation of TIRC team was around the existing methodology. TIRC team integrated CEAD at the conceptual-3D prototype-CAE stage, and used the tool to build in predictive engineering analysis into its development methodology, or simply creating an engineering design synthesis stage.This innovative methodology, coupled with CEAD, has resulted in TIRC being able to build in engineering constraints into conceptual 2D geometry drawings, thus allowing for early stage insight into manufacturability prior to investing the time and effort to create a detailed 3D virtual prototype.

This process and tool innovation at the engineering R&D level has resulted in a more efficient product development methodology, which has resulted in three critical business impacts for Terex:

• Higher product quality due to a more integrated and better engineered design.
• Reduction in cost due to significantly shortened and more streamlined product development cycle.
• Better internal design delivery to stakeholders downstream of product development process due to the tool architecture for product optimization.

Customer Testimony
Dr. Krishna Prasad, Executive Director of Terex India R&D Center says –
“Our approach to NPD (New Product Development) is very process driven and TIRC is happy to have found a business partner in CADVision at the appropriate time. The CEAD tool had helped our engineers work at a faster pace with reduced repetitive work on analytics. We have started using this tool on many more projects and have seen that the team has adapted well to it”

Conclusion
In summary, the combination of TIRC’s innovations in process methodology and CEAD integration into the design flow has resulted in tighter integration and better value, resulting in faster, higher quality and effective response to fast changing market needs.

CADVision Engineers, a provider of engineering software products and services, announced today the completion of phase one of beta testing on a software product that uses Bricsys’ LGS 2D component technology for parametric constraint solving. The product is a first level computer aided software tool that an engineer would use in creating sketches of concepts, progressing to synthesizing geometry and concluding with analyzing the integrity of design to quickly assess practicality of a design concept.

CADVision believes this is a smarter methodology that uses Engineering Design Synthesis to shorten design cycles and thus time to market or time to complete engineering change/configuration orders.

Phase One of beta testing and product debugging is complete, and the company expects to complete phase two by mid 2014, with commercial availability beginning shortly thereafter. CADVision expects to make a formal announcement of the commercial launch and other details in the middle of the year.

Originally acquired from LEDAS, continuous improvement of the LGS 2D & 3D component technology is now led by the Bricsys development team in Novosibirsk, Russia. The technology is available for integration by CAD/CAM/CAE software developers worldwide, and has been embedded in the BricsCAD software itself since V12. As such it is used by thousands of BricsCAD users for parametric drawing, variational direct modeling, assembly design, and kinematic simulation.

CADVision Engineers licensed LGS 2D from Bricsys to implement constraint support in its brand-new software product. Using the full power of LGS 2D, Design Engineers can solve complex engineering problems early in their design cycle.

“We thoroughly analyzed several technology components for constraint solving available on the market and selected LGS 2D from Bricsys,” said Siddharth Reddy, Director of CADVision Engineers Pvt Ltd. “It perfectly suits our needs in a powerful constraint solving engine that is able to support sophisticated engineering design. We are also happy with its affordability for start-up companies.”
“Hundred thousands of BricsCAD users worldwide are aware of the power of our constraint solving technology,” said Erik De Keyser, CEO of Bricsys NV. “We are happy to share our many-years experience in this field with other CAD development companies. We propose flexible conditions for start-up companies interested in our state-of-the-art technologies for parametric design in 2D and 3D.”

CADVision Engineers Private Limited, a provider of engineering software products and services, announced today the launch of their first engineering software Product CEAD. Standing for Conceptual Engineering & Analysis Based Design, CEAD has been developed to be used in conjunction with Constraint Driven Engineering Design Synthesis methodology, a novel approach to the traditional bottom up product design & development process currently used globally that helps engineers in the following ways:

• With geometry and math concurrently described on the design canvas, CEAD enables engineers to intertwine any set of mathematically consistent engineering constraints to the design even if they belong to different domains of physics.
• CEAD has tools to perform multi-objective optimization.
• CEAD enables first cut analysis of forces, torque stresses, etc using vector mechanics.
• Simulation functionality in CEAD enables engineers to see deep into the product development cycle, be it in manufacturing or machine performance

CEAD is an integrated product design environment enabling preliminary hand sketches to conceptual CAE that provides a rational design foundation for a more time-intensive CAD and CAE later in the product development cycle. It is the first level computer aided software tool that an engineer would use in creating sketches of concepts, progressing to synthesizing geometry and concluding with analyzing the integrity of design to quickly assess practicality of a design concept.

“With many years of experience in the software development & mechanical design domains, our software product development journey began in 2010, and today’s announcement is a reflection of several years of intense effort by our R&D team,” said Siddharth Reddy, Director of CADVision Engineers Pvt Ltd. “CEAD is built on a constraint solving engine that is able to support sophisticated engineering design, which when used in conjunction with the Constraint Driven Engineering Design Synthesis Methodology will result in smarter conceptual design. This essentially means more innovative ideas can be evaluated at the conceptual stage and fewer iterations at the engineering analysis stage hence shorter design cycles, time to market and engineering change/configuration orders, while increasing quality and predictability of manufacturability”, he added.
