Large optimization effects through small measures

Thanks to automation of inspection plan creation, Jos. Schneider Optische Werke GmbH saves up to 50% of the time and significantly reduces the susceptibility to errors

Many companies still have gaps in the process chain when it comes to quality assurance

Using digital data more consistently in quality assurance also opens up great potential for rationalization

 

Challenges

  • Growing complexity of parts leads to exponential increase in prototype development costs
  • For customer-specific development, but also for catalogue products, the product developers at Jos. Schneider are under considerable time pressure
  • Many errors occur when marking dimensions, tolerances, etc. that are relevant to the inspection, despite a high time expenditure
“The manufacturers of professional cameras introduce a device with a new sensor every year. We have to adapt to this in lens development, which means, among other things, saving a lot of time with many small measures along the entire process chain.“

Goals

  • With the help of the NX Nastran software, FE analyses are to be used to increase the degree of maturity in the early phase of product development in order to shorten development cycles and to have to build fewer real prototypes
  • Time saving through drawing management with 3D instead of 2D
  • Reduce development costs and development times in order to be able to adapt the lens development to the customer's needs
  • Save time when creating the inspection plans
  • Important information for NC programming is to be attached to the 3D model as PMI (Product Manufacturing Information) and automatically evaluated by the NC programming

 

Lessons Learned

  • Automation of the creation of inspection plans is possible with the BCT Inspector. The software accesses NX drawings and manufacturing information in the model, automatically selects the quality-relevant characteristics for the inspection process, numbers them and compiles the values in a table
  • Automating test plan generation can save up to 50% of the time and significantly reduce the susceptibility to errors
  • Even if the characteristics are extracted from a drawing for the inspection plan, they know their reference points or surfaces thanks to the associative link between the drawing and the 3D model
  • The digitalization of the measurement programming allows the parallelization of certain activities in production and quality assurance, which brings time advantages especially in the prototype business. After production, the inspection program for the part is already available.
“We have clearly become faster, but this is not only thanks to the IT tools we use, but also to better cooperation between different areas.“
