Product Design Support, Customization and Parameterization

Industrial/Conceptual Product Design: Conceptual engineering is an important phase of the development process, in which rapid idea capture is paramount. Conceptual design is the explicit construction of ideas or concepts to visualize a product and for alternative designs to evolve. TekSaga will take your product from Concept to Reality. Based on customer specifications, we will evaluate numerous concepts and develop the one that best fits the needs. Product Cost, Time to Market and Product Quality are our primary concerns. Our concept design process encompasses digital visualization with 3D layout for packaging studies. While we design we will take care of the down steam applications like simulation, tool design and manufacturing.

Project Support and Process Automation:TekSaga will assist you in any stage of your project. When you work with us, we become an integral part of your team and are fully committed to meeting your project goals and delivery schedules. Our services include model generation, production drawing creation, Tooling, simulation and manufacturing.

We understand that our customers always want to develop efficient methods to reduce the product design cycle time. We help companies automate their design processes through the creation of "Template" parts and assemblies, which reduces the product design cycle considerably. TekSaga will also develop "best practices" and process documentation to help automate the creation of similar products.

TekSaga engineers have the experience, background and tools to help you convert your ideas into real products.
 CAD Data Migration Services

TekSaga customizes the data migration process for each customer's specific requirement. TekSaga's custom data migration projects create consistent models that incorporate the original design intent of your design. This makes future redesign steps easier, and the reusability of your 3D CAD data can dramatically shorten the design cycle for new products. You can expect to save time and money while gaining a competitive advantage in your industry.

Benefits from our services:
  • An average cost savings of 60% to 70% versus the costs of performing data conversion in-house.
  • Guaranteed data consistency and quality meets your specifications.
  • Reusability in both upstream and downstream applications makes faster time-to-market and reduced costs.
  • Increased time for your design team to focus on core design tasks.

Legacy CAD database migration is not an automated process. Models have to be created or rebuilt incorporating design intent step by step. Now you have an opportunity to have this data converted to your CAD platform of choice at a price you can afford, and in a timeframe that is realistic. TekSaga engineers can take your products from paper drawings through 3D modeling to complete manufacturing solutions, while your engineers continue to focus on on-going projects.

TekSaga specializes in efficient, intelligent CAD data conversion. We combine high-caliber engineering talent, customized specifications, secure data environments, and a global infrastructure to provide best-in-class solutions.

Incorporation of Standard Procedures in Data Migration Projects

General Modeling and Documentation Methodologies

Companies implementing CAD Software must develop and document standards and methods for the use of CAD Software. There will be a lot of interaction between CUSTOMER and the TekSaga consultants dur­ing the development of these company standards. The goal is to have a pre-thought-out method for modeling each item so that the following conditions are met:

  • The model and drawing are maintainable and modifiable by someone other than the original modeler.
  • The model is robust in terms of downstream uses: assemblies, detailing, analysis, and manu­facturing.

Numbering schemes

Establishment of a numbering scheme is of major importance internal tracking of drawings within CUSTOMER, also for designing in the CAD Software environment. Because of the associativity of CAD Software files, unique names must be assigned to parts, assemblies, drawings, family table instances, etc. In addition, the numbering scheme can actually be a way of categorizing files that can be later tracked in PDM. This categorization of parts and assemblies will help to eliminate duplication of design effort.

Authorization and revision procedures

Access to the database can be controlled by setting authorizations for access to files. Revision history is automatically tracked which includes the date of the change; the user who made the change as well as a host of other information that can be tracked. Files can be promoted or demoted to different release levels such as release for manufacturing or release for preliminary design. These procedures should be established early in the project so that information can be tracked from the earliest portion of the design cycle.

Formats and drawing conventions

Formats and drawing convention should be established early in the project. Information can be added to the parts and assemblies in the form of “parameters” that can later be automatically added to the drawing format. Information such as designer, drawing creation date, and revision level of the part are all information that can added to the drawing automatically when the user identifies which part or assembly he is making a drawing of. Drawing conventions, such as standard text heights, dual dimensioning, arrow lengths, etc. can be controlled from one location so that drawings will be created to CUSTOMER specifications. Automatic BOM’s are able to be displayed in customized formats.
 Complex CAD Models, Very Large Assemblies

TekSaga has vast experience in handling casting part modeling in various CAD Systems and handling very large assemblies.

Over the time, we have carried out various projects in this field and refined the process. Based on the customer requirement or by using customer suggested methodologies, we can effectively create 3D Models of the complex casting parts.

We have explained one of the commonly used method as follow;

In this method, the complex model is divided into small portions. Generally divided into small portions similar to mold or pattern split including cores. A part-control-assembly brings the parametric relationship among parts. Actual manufacturing of casting part is simulated, drafts and rounds are given all parts including cores and pattern parts, any serious change in thickness due to draft requirement, can be detected early.

  • Faster Regeneration: Models are split into small portions, hence contains less features in each part.
  • Time Reduction: This procedure allows multiple people to work on the same complex component simultaneously.
  • Model can be completed much faster than normal procedure.
  • Many modeling difficulties can be solved using surface method and proper model split.
  • Part or drawing file can be opened independently. Assembly needs not to be in memory.
  • Final casting/finish part size is small. Faster regeneration in assembly.

Rapid Prototyping and Rapid Tooling: Rapid prototyping provides a conceptual physical representative model of a part fro design visualization and lab tests. Engineers can use this to check form and fit and perform limited functional tests. This enables design verification easy like never before.

TekSaga has channel partners for rapid prototyping, we can provide Sintered Metal , SLA, LOM and ABS prototypes of product designs. We also provide Rapid Tooling for plastic injection molded components and Investment castings.

Parameterization & Customization - Automation of Model Generation

CAD/CAM software packages offer very versatile and generic capabilities that can be reasonably used "out-of-the-box" by most users. However, customization of software functionality can significantly boost productivity of the design office, while improving compliance with company standards and practices. TekSaga can expand the capabilities of the "standard" CAD software packages by writing program code, including integrating custom applications with basic package.

Today CAD software offer abandon possibility of automation and customization. The extent automation achieved can be explained by a typical example.
