Blueprints
Where is the main source of information regarding part material and unspecified tolerance?
What is the Title Block?
To safely cut high-alloy steel without burning out his tool, a machinist mounts a half-inch diameter carbide cutter and sets his target surface speed to 100 SFM. Using the standard machining formula, this is the resulting spindle speed, rounded to the nearest whole revolutions per minute.
What is 763/764 RPM (exactly) or 800 RPM (roughly)?
A rectangular plate mounted to the saddle.
The bar attached to the spindle of a vertical milling machine
What is the drawbar?
A wrench that can be used on various sizes.
What is an adjustable wrench? (farmers wrench)
The desired measurement of a feature on a part.
What are Dimensions?
When squaring up an aluminum plate using a 1.25-inch indexable endmill, a CNC operator targets a cutting speed of 225 SFM. Using the standard speed formula, this is the resulting spindle speed, rounded to the nearest whole revolutions per minute.
What is 687 and 688 RPM(exact), or 720 RPM (roughly)?
The rate at which a workpiece and cutting tool move past one another at their point of contact.
What is Cutting Speed?
A milling operation that produces a flat workpiece surface. This type of milling is used primarily on the top workpiece surface.
What is Face milling?
A tool used to remove burrs from a part.
What is a file?
A drawing that communicates the shape and size of an object in three dimensions by showing three sides of the object from one perspective. These are not frequently utilized in blueprints.
What are Isometric Drawings?
Optimizing a roughing pass in 6061 aluminum with a 7/8-inch carbide endmill calls for a cutting speed of 325 SFM. Using the standard machining formula, this is the required spindle speed, rounded to the nearest whole revolutions per minute.
What is 1485 RPM? (roughly) 1419 RPM (exactly)
The base of a lathe carriage assembly
What is the saddle?
The part of a vertical milling machine that holds the spindle. This also contain various speed and feed controls for the mill.
What is the Head?
A pen like layout tool, sometimes used to mark lines.
What is a scriber? or scribe?
A line used to define the shape and size of a part feature and represent the visible edges of the part.
What is an object line?
Pushing the limits during a high-speed profiling pass in aluminum, a machinist sets a 3/8-inch solid carbide endmill to a target cutting speed of 875 SFM. Using the standard machining formula, this is the required spindle speed, rounded to the nearest whole revolutions per minute.
What is 8913 RPM (exactly) or 9,333 RPM (roughly)
Unlike its self-centering 3-jaw relative, this lathe workholding device requires a dial indicator to manually align a workpiece because each of its grips is adjusted separately.
what is a four jaw chuck
What is the Knee?
A simple measuring instrument consisting of a long, thin metal strip with a marked scale of unit divisions.
What is a steel rule?
A numerical expression representing a part of a larger whole or proportion.
What is a ratio?
Running a high-feed facing pass on a stainless steel workpiece, a machinist selects a 1.0-inch endmill with a target cutting speed of 415 SFM. Using the standard machining formula, this is the resulting spindle speed, rounded to the nearest whole revolutions per minute.
What is 1,585 RPM? (exacly) or 1660 RPM (roughly)
The mount for the toolpost
What is the compound rest?
A shaft that moves the spindle in and out of the mill head.
What is the Quill?
A thin metal tool that has a raised mirror image of a letter, number, or symbol at one end.
What is a stamp?
