The speaking module

II. Speaking Exercises:

Exercise 1. Describe an artifact , Renishaw probes, manufacturers   using the suggested words and expressions as in example:

on-machine verification technology

comprises , in-process probes, inspection software, manufacturers ,automatically monitor, correct, document, in-process operations

On-machine verification technology comprises in-process probes and inspection software that lets manufacturers automatically monitor, correct, and document in-process operations.

an artifact

a master part, made from, the same material, the same manufacturing operations ,as ,parts ,being machined. 

Renishaw probes  

don't require, calibration, the vectors, in which , be used.

manufacturers  

can use ,this technique ,any machining center, near ,the machine's repeatability specification, as well as, for thermal effects.

Exercise 2. Ask questions to the given answers:

  1. Question: ___________________________________________ ?

Answer: Any difference can then be compensated in machining that feature on the workpiece.

  1. Question: ___________________________________________ ?

Answer: Such a level of precision may be impressive, but it's rarely needed in most manufacturing operations.

  1. Question: ___________________________________________ ?

Answer: The inspection software allows CAD-to-part comparison, with GD&T capabilities such as perpendicularity, angularity, parallelism, and concentricity.

  1. Question: ___________________________________________ ?

Answer: Next, the artifact is located in the machining envelope, usually as part of the fixture.

  1. Question: ___________________________________________ ?

Answer: An artifact is a master part made from the same material by the same manufacturing operations as parts being machined.
