New Technology from SolidWorks for Quality Inspection

Quality Inspectors examine products and materials for defects or deviations from specifications. Quality inspectors mark tag or note problems. They may reject defective items outright, send them for repair, or fix minor problems themselves. If the product is acceptable, the inspector certifies it. Overall, Quality Inspector plays a key factor in delivering products faster and ensure error free production in an organization.

Quality control inspectors typically do the following:
• Read blueprints and specifications
• Monitor operations to ensure that they meet production standards
• Recommend adjustments to the assembly or production process
• Inspect, test, or measure materials or products being produced
• Measure products with rulers, calipers, gauges, or micrometers
• Accept or reject finished items
• Remove all products and materials that fail to meet specifications
• Discuss inspection results with those responsible for products
• Report inspection and test data

Quality inspectors ensures quality standards for nearly all manufactured products. Specific job duties vary across the wide range of industries in which quality inspectors work. Quality control Engineers rely on a number of tools to do their jobs. Although some still use hand-held measurement devices, such as calipers and alignment gauges, workers more commonly operate electronic inspection equipment, such as coordinate-measuring machines (CMMs). Quality Inspectors record the results of their inspections through test reports. When they find defects, inspectors notify supervisors and help to analyze and correct production problems.

SolidWorks Introduces a great tool for Quality Inspectors to reduce their workload and create error free reports with ease. SolidWorks Inspection helps in creating First Article Inspection report, PPAP (Dimensional Test Report), Process Performance Report, AS9102, etc. Balloon drawing creation made easy now as SolidWorks Inspection Captures all Characteristics in a drawing. Hence Quality Assurance can easily built their reports faster and error free.

SolidWorks Inspection Capabilities:
  1. Automatic Balloon Creation process using OCR(Optical Character Recognition)
  2. Automatic Report Creation Process with single click
  3. Compare and Replace Ballooned drawing
  4. Easily Find the missed characteristics to balloon
  5. Integrate with QualityXpert & Net-Inspect to track the supply chain in detail
  6. Integrate with Digital Instruments to enter measured value automatically
  7. Import CMM results to auto-assign based on nominal and Tolerance results
  8. Results showcased in Color codes based on results
  9. Results showcased in best worst and average based on the measured inputs.

Quality Inspector spends 90% of their time in inspecting the product quality and their conformation. This tool, SolidWorks Inspection ease their jobs by automating the balloon creation process, Report creation process and Check Conformity of the part. SolidWorks Inspection helps in to ensure all products sold to customers are of the highest possible quality.

Confused With Wire/Cable Harnessing? - Harnessing Technology By SolidWorks Electrical

SolidWorks Electrical is an intuitive and powerful tool which takes care of wire and cable harness design and create the flattened view with automatic updated BOM/Cut.

Engineers need to put more thought into thinks like wire length, bending radius and routing. As wiring harness become increasingly complex and an important part of design we are in need of a powerful tool to ease our design process, this is where SolidWorks Electrical comes into play.

Today in Automotive sector there are many more computers and Electronic Control Units used in vehicles today. These ECU are used to control the transmission, and other major devices of the vehicle and they have to be connected via wire harness in order for the system to work

What is Wire Harness?
The wire harness is compactly bundled wire which plays as the conduit for transmission of control and power signals acting as the “Central Nervous System of a vehicle”.

When designing a new product, engineers focus mainly on functionality, features, styling, and cost. What they don’t always think about is the wiring part.
SolidWorksElectrical provides you the highly simplified auto-routing of wire, cables, and harness and generate their reports automatically and enables last minute harness design changes by utilizing advanced harness technology saving your design cycle time.

Benefits Attained:
  • Reduces the Harness Scrap
  • Reduced cost - accurate harness reports
  • With stand last minute Design changes

Mobile Phone Back Case Structural Simulation

Mobile Phones nowadays have become so handy among people & the Design Innovations undergone by the phone companies are so pretty big. The back mobile case cover is mostly prone to failures as it is the most critical component for the real world applications. During the mid of 2015 year, some non standard tests were undergone on the back case products for failure mode analysis. Let's have a quick look on how SolidWorks Simulation offers the design principles in solving the real time problems.

A general Static analysis is performed to verify the failure zone on the case covers. Since these tests require some physical bending & hardened strength of material, the linearization of the problem is the upmost priority for verification.

To validate this product, firstly we need make some assumptions & simplification of the problem. The initial assumption made here is a person sitting on the back of the mobile phone weighing 70kgs. The model thickness (Shell thickness) was considered to be 1.5mm, which purely stiffens the geometry towards bending.

ANALYSIS Conditions:
  • Material : Aluminium - 6061 Alloy (From Material database). The material assigned to the product is manufactured of Aluminium material as in actual cases. The material database present in SolidWorks Simulation gives users with multiple options in material selection with customized library.
  • Boundary condition : Side faces of the model are restrained with all the degrees of freedom (Selection on faces/ edges).
  • Loads : Force = 70kgf (Normal to the back face reference). Depending on the complexity of the problem, we can apply loads as Force or Pressure as indicated.
  • Mesh Parameters : Solid Mesh with curvature based mesh type was used. The element size of 1.2mm was used globally throughout the geometry.
SolidWorks Simulation gives beautiful color plots for the user for easy review of the results. For validating this mobile case product, we need to review the results like Stress, Displacement, F.O.S. & Fatigue Life cycle.

To be more precise on the results, SolidWorks Simulation offers to perform Non-Linear Static studies for time based loading conditions. The loads assigned for reference can be indicated with respect to Time curve, or if we use Rubber / Plastic materials in analysis, we can use the Stress-Strain curves for various models for validation.

  • Shortest learning curve
  • Ease of use in conducting virtual based simulations
  • What-if scenarios on models, loads & material conditions
  • Integrated platform where designers become analysts
