Clip 1: What is Tolerancing...
This is a basic introduction to tolerancing as a subject - it summarises what is covered in the WinLens Tolerancer manual.
For the optical engineer there are five key questions that need to be answered when converting a paper design into a successful product.
- What are the errors that can happen in the manufacture of this design
- What are the performance effects of those errors individually
- What limits [tolerances] do I need to place on those errors
- What will happen when I make a batch of lenses to those tolerances
- How can I get the glass shop and machine shop to follow those tolerances
We discuss these very briefly!
Clip 2: Tolerancer: an introduction...
WinLens Tolerancer is designed to help you create sensible tolerances for your lens system [the design must be rotationally symmetric]
This clip provides a very quick run thru of the tools available to help in tolerancing:
- Standard graphs from WinLens
- Define performance requirements
- Sensivity analysis - tables of data - linked to the graphs
- Tolerance editors - statistical feedback & many tools for tolerance assignment
- Monte Carlo simulations of a batch of lenses made to current tolerances - linked to the graphs
- ISO 10110 drawings - editor and flexible preview - highly customisable
