Mid-Term Flashcards
A _______ surface is created by trimming a flat surface to a specified boundary.
Flat boundary
A _____ surface is created by rotating a sectional shape around an axis or line.
Revolved
Surface ______ is used to machine cavities or bosses on surfaces and solid models.
Rough pocket
______ construction mode allows you to create all geometry to the current construction plane and at the current Z depth.
2D
A _____ surface is created by making a linear transition between two or more open or closed contours.
Ruled
_____ toolpaths are generally used on rounded shaped parts or areas.
Radial
It is necessary to have _____ curves to create a net surface.
3
You would use a surface finish ______ toolpath when the part requires the cuts to conform to the part shape.
Contour
A _____ surface is used when the across section is constant and when you only have one across contour and one along contour.
Swept
A ______ toolpath is used to clean leftover material out of corners.
Rest mill
The advantage of using a ______ toolpath is it allows you tto control the scallop height of the part.

If you chose to overwrite the tool number from the library with the next available tool number, you would use the command “assign tool numbers _______”
Sequentially
The height at which the tool rapids to or from the part is known as Tool _________ value.
Clearance
When a pocket can be closed wint an imaginary line, and the toolpath will overlap the line with a percentage of the tool diameter, use _____ pocket toolpath.
Open
What command allows you to create an arc knowing the radius, the center of the arc and the initial and final angles? _____
Arc polar
If you click on the icon in front of a value in the ribbon bar, you _____ that value.
Lock
