Glossary of terms

In this place, the following terms or expressions are used with the meaning indicated:

flow drilling

Friction drilling, also commonly known by the trademarked name Flowdrilling, is a non-machining method of making holes in metal, in which the material is melted by adding high pressure and friction energy.

frame

frame is a structure surrounding a second structure

passpartout

Passe-Partout (or passepartout) is the French term for a mat, a paper or, more usually, cardboard sheet with a cutout, which is placed under the glass in a picture frame . A picture (a photo or print, drawing, etc.) is placed beneath it, with the cutout framing it. The passe-partout serves two purposes: first, to prevent the image from touching the glass, and second, to frame the image and enhance its visual appeal. The cutout in the passe-partout is usually beveled to avoid casting shadows on the picture.

squeezing

means to compress the material in a locally limited area (e.g. by a rounded edge) to such an extend, that the material is displaced and hence tensional stress is produced to such an extend that the material is severed.
