1 - Why in a CAD system you need the levelled distribution of geometric entities?

_ Because entities with different graphical attributes cannot lay on the same level. Because you can organize the represented geometry at the best. Because so you can quicken the video performances. Because in any case the dimensions can lay on the same level of the geometry.

2 - During the milling the operation of  spot drilling, punching and tapping are not working because they are made with specific drilling machines.

_ True False

3 - To open a file coming from a CAD system different from the one in use you need to …

_ … have a specific declaration release by the producer of the original system. … perform a copy and paste operation within the target system. … use the import functions of the system. … make sure that all the geometric entities lay on the same level.

4 - What is a spindle?

_ An instrument for holes measure. A tool needed to perform bevels. A blocking system. A sensor for the tool movemnt control.

5 - What is a concatenation?

_ A selection where the entities have a coincidence between their final point and the starting point of the following one. A method of grouping those entities which are similar because of the same graphical attributes. A link between two different entities. A profile that defines a closed area.

6 - A CAD-CAM system has all the options for the drawing or created model printing so that you can put on the paper everything you made.

_ True False

7 - To measure the length of an entity in Mastercam you need to …

_ … insert a dimension on the drawing by setting at least one decimal value. … insert a tolerance dimension the measure the real dimensions of an entity. … use instruments for the analysis of those entities existing in the system. … set the real video scale and measure with the specific “rule” function existing in the system.

8 - A CAD-CAM system doesn't use colour attributes,it uses only black because drawing rules say so.

_ True False

9 - If I want to make a circle in Mastercam I must …

_ … use the specific functions existing within the arch creation menu. … define the square inscribed in a circle. … create a polygon with infinites sides. … insert the value of the circle ray and circonference.

10 -  Mastercam doesn't allow you to create, more than the CAM operation, even geometric entities like points, lines, arches, spline, surfaces and solids.

_ True False
