Are used to guide tools to the correct location and are used to guide a workpiece?
Jig: A jig is a device which supports the workpiece and holds the workpiece intact at the proper location with the help of locators.
It guides the cutting tool in most of its usages to ensure that the operation is done at the exact place and it is primarily used in drilling and reaming operation..

What is the most common workholding device?
drill press viseDrill vise is a holding device used for clamping most workpieces while drilling. One of the most commonly used work-holding devices is also called a drill press vise. The vises provide the quickest and most efficient set up method for parallel work. Available in many sizes.
What devices are used to hold a workpiece in a lathe spindle?
Collets – A slotted sleeve which when expanded or contracted by a tapered collar or rod, grips a cylindrical workpiece on its inside or outside diameter. Collet Chucks – To machine a workpiece that is turning while being machined, typically in a lathe, a chuck is used to secure the workpiece to the end of the spindle.
What are tool holding devices?
Tool-Holding Devices A tool holding device consisting of adjustable jaws that center a workpiece in a lathe or center a tool in a drill. clamp, clinch. a device (generally used by carpenters) that holds things firmly together.
What size collet should I use?
Your first consideration should be the size of end mills or drills you will be using most often. If you are doing smaller work you would require smaller diameter range collets. Generally you may prefer the ER16 and ER32 sizes. If the bulk of your tool requirements are in the mid range you can also use the ER20.
What are ER32 collets used for?
An ER collet can be used in drilling, reaming, and tapping as well as milling applications just by exchanging the collet. Its accuracy also provides greater tool life than older style collet systems like TG or DA.
What is the difference between ER32 and er40 collets?
There is really no difference in the 2. The ER-40 collets are thicker. But the ER-32s are the most commonly used.
Which of the following is the example of multi point cutting tool?
Which of the following is the example of multi point cutting tool? Explanation: Milling cutter and broaching tools use multi point cutting tool to perform their operations. In milling, material is removed as the work is fed against a rotating multipoint cutter. Broaching also remove material but high accuracy.
What is six point location principle?
3-2-1 Principle of Location used in Jig & Fixtures:  It is also known as six pin or six point location principle. In this, the three adjacent locating surfaces of the blank (work piece) are resting against 3, 2 and 1 pins respectively, which prevent 9 degrees of freedom.
What are the characteristics of a good work holding device?
Workholding devices provide fundamental functions, locating and clamping.Locating refers to orienting and positioning the part relative to the cutting tool.Clamping refers to holding the part in its proper orientation with enough force to resist the force of cutting but not deform the part.
Which scenario may require a customized Chuck?
Which scenario may require a customized chuck? Machining particularly large workpieces.
What are the principles of location?
The 3-2-1 principle of location (six point location principle) is used to constrain the movement of workpiece along the three axes XX, YY, and ZZ. This is achieved by providing six locating points, 3 pins in base plate, 2 pins in vertical plane and 1 pin in a plane which is perpendicular to first two planes.
What are boring tools?
: a boring bit with its supporting boring bar and arbor, used to enlarge and accurately finish a large bore previously formed by casting or otherwise.
What is one of the two most common lathe workholding devices?
CHUCKS. Chucks are probably the most widely adopted type of workholding device on the lathe. They are efficient and accurate and work well with most types of workpieces.
Which ID operation is used to create a smooth finish on a workpiece interior?
Finish turning on a lathe, which follows rough turning , produces a smooth surface finish, and cuts the workpiece to an accurate size. Factors such as the condition of the cutting tool bit, the rigidity of the machine and workpiece and the lathe speed and feedrate, may affect the type of surface finish produced.
