One of the two major types of production drawings showing an individual part.
What is a detail drwing
100
The amount of size variation permitted for the size, form, or position of a feature included in a manufacturing drawing.
What is a tolerance?
100
A process of producing a metal object by pouring molten metal into a mold.
What is the Casting process?
100
The general class of production tooling representing the shape and/or size of the parts to be made.
What are Patterns?
100
This size tolerance only gives the largest and smallest size.
What is a limit tolerance?
200
One of the two major types of typical manufacturing drawings, showing several parts put together and containing pertinent information, such as a bill of materials.
What is an assembly drawing
200
The total size variation (between the high and low limits) specified by a tolerance on a manufacturing drawing.
What is a tolerance range?
200
In foundry terminology, the taper or relief put on the sides of a pattern to enable it to be withdrawn from the molding material, e.g., sand.
What is a draft?
200
So named because the pattern is "lost" in the process.
What is Investment casting?
200
This tolerance is for the shape of teh feature.
What is a form tolerance
300
This is an item always found on a detail drawing but never on an assembly drawing.
What are dimensions?
300
Repeatability; the amount of size variation in the component or product features created by a manufacturing process
Daily Double
What is Precision?
300
In foundry terminology the top half of a split mold used in casting.
Daily Double
What is the cope?
300
In foundry terminology a combination of sand, clay, and water to be used in molding.
What is Green sand?
300
This tolerance is for the size of the feature.
What is a size tolerance?
400
The deatil drawings and the assembly drawing combined together are referred to as this.
What are the working drawings.
400
This size tolerance only permits the feature to either increase or decrease but not to do both.
What is Unilateral tolerancing?
400
In foundry terminology the bottom half of a split mold used in casting.
What is the Drag?
400
The amount added to the dimensions of a casting pattern to make allowance for the shrinkage that will occur when the metal solidifies and cools.
Daily Double
What is the Shrink allowance?
400
These molds may be made so that the “halves” may be hinged or mounted on a casting machine so that they can be opened and closed quickly.
What is a Permanent Mold?
500
The working drawings and the specifications are part of what set of documents?
Daily double
What are the contact documents.
500
A general rule that is commonly followed manufacturing.
It specifies that the precision of measuring process should be no worse than 10 percent of the tolerance range (from the manufacturing drawing) for the feature that is measured.
Daily Double
What is the Rule of Ten?
500
In metal casting, this vertical opening in the mold serves as a reservoir to supply molten metal to the casting as it shrinks during solidification.
What is the Riser?
500
In foundry terminology, a sand and oil form, strengthened by heating, used to create voids (holes, cavities) in castings
