SHAPING Flashcards
What is the main purpose of a shaping machine?
To produce flat surfaces – horizontal, vertical, or inclined.
Can modern shapers cut curved surfaces?
Yes, modern shapers can generate curved or irregular surfaces too.
What type of cutting tools are used in shaping machines?
Single point cutting tools, similar to lathe tools but sturdier.
How is a horizontal surface machined on a shaper?
The workpiece is held in a vise or clamped on the table, and the shaper machines the flat surface.
What is vertical shaping?
Cutting the vertical side of the workpiece with the tool fed downward.
How is the vertical surface aligned in shaping?
It is parallel to the ram movement.
What tool is used to cut slots or keyways on a shaper?
A square-shaped tool.
What preparation is done before cutting keyways?
The ends are drilled to required depth using a drilling machine.
At what speed is slot or keyway cutting performed?
At a slow speed.
How is the table/tool adjusted for angular surfaces?
The tool slide is swivelled to the required angle; table may also be swivelled.
How is the angular feed provided?
By rotating the tool feed handle.
Why is the apron tilted away from the work?
To avoid tool rubbing during the return stroke.
What type of tool is used for shaping irregular surfaces?
A round nose tool.
What kind of surfaces can be shaped as irregular surfaces?
Concave, convex, and other non-flat profiles.
How are feeds given while shaping irregular surfaces?
Cross feed through the table and vertical feed by the tool feed handle – both simultaneously.
Why is the apron adjusted during irregular shaping?
To avoid rubbing during the return stroke.
