How does a threshing machine operate?
A threshing machine is used too seperate grains like wheat from the stalks.This was onc a proces that was done by hand and was more time consuming.
What are strapping machines used for?
Strapping machines are used for winding the strapping onto objects firmly and securely. This is best done with a machine if a high tension is required because they can hold the strapping more tightly.
What can be done to increase the efficiency of the machine?
Mechanical Efficiency is the ratio of Actual mechanical advantage to ideal mechanical advantage.Efficiency will be maximum when Actual mechanical advantage equals that of ideal.But practically not possible.Actual mechanical advantage will be less due to friction,heat,deflection etc.avoiding these loses will increase the machine efficiency.
What do CNC operators do?
A CNC operator, as the name suggests operates a CNC (computer numerical control) machine, usually this includes loading and unloading workpieces, checking workpieces, setting program datums, setting up jigs and fixtures, replacing worn or broken tooling, cleaning swarf from the machine and basic machine maintenance. Some operators also do programming although this is usually limited to altering a program to suit the tools being used; for example altering a program to give the correct drill depth after changing the drill. The exact duties of a CNC operator varies from one machine shop to another. A CNC programmer actually writes the program that runs the machine although this job is increasingly done by software.
What is done when a force moves and object through a distance?
Work is done.
What is parallel turning on lathe machine?
Parallel strips, which are hardened and ground steel pieces sold in matching pairs, are used in a vice or bolted to the machine table to support and accurately set jobs. Their purpose is to provide clearance so drilling and tapping operations can be done without cutting into the machine table.
To drill oil do you have to cut down trees?
Some oil drilling is done on rigs at sea, where there are no trees. Some oil drilling is done in countries that are primarily deserts.
What is Engineering Workshop practice?
Engineering workshop practice refers to a series of operations done regularly in a small establishment where handcraft and manufacturing works are done. These operations include production of machine components, metal work and woodwork.
What is difference between reaming and drilling?
Drilling is a cutting process in which drill is used to make a hole. Drilling process usually creates rough surfaces. Therefore, reaming is done after drilling to make a good surface finish, without changing the chemical and physical properties of the material. In reaming, only 5% of the material is removed (rest is removed by drilling process done before).
What should be done to prevent a person from falling from height while working on radial drilling machine or while welding at height by sitting on shell and welding the nozzle the height around 4 mtr?
4000ft
What is the meaning of ground operations?
operations done on the ground lol
What do major computer operations include?
Major operations are three operations: Compiling and processing data done by CPU Graphic Generation and processing done by GPU Arithematic and logic Processing Done by ALU
Types of drilling machines?
Basic Types of Drilling MachinesDrilling machines or drill presses are one of the most common machines found in the machine shop. A drill press is a machine thatturns and advances a rotary tool into a workpiece. The drill press is used primarily for drilling holes, but when used with the proper tooling, it can be used for a number of machining operations. The most common machining operations performed on a drill press are drilling, reaming, tapping, counterboring, countersinking, and spotfacing.There are many different types or configurations of drilling machines, but most drilling machines will fall into four broad categories: upright sensitive, upright, radial, and special purpose.UPRIGHT SENSITIVE DRILL PRESSFigure 1 Upright sensitive drill pressThe upright sensitive drill press (Figure 1) is a light-duty type of drilling machine that normally incorporates a belt drive spindle head. This machine is generally used for moderate-to-light duty work. The upright sensitive drill press gets its name due to the fact that the machine can only be hand fed. Hand feeding the tool into the workpiece allows the operator to "feel" the cutting action of the tool. The sensitive drill press is manufactured in a floor style or a bench style.UPRIGHT DRILL PRESSThe upright drill press (Figure 2) is a heavy duty type of drilling machine normally incorporating a geared drive spindle head. This type of drilling machine is used on large hole-producing operations that typically involve larger or heavier parts. The upright drill press allows the operator to hand feed or power feed the tool into the workpiece. The power feed mechanism automatically advances the tool into the workpiece. Some types of upright drill presses are also manufactured with automatic table-raising mechanisms.Figure 2 Upright drill pressRADIAL ARM DRILL PRESSThe radial arm drill press (Figure 3) is the hole producing work horse of the machine shop. The press is commonly refered to as a radial drill press. The radial arm drill press allows the operator to position the spindle directly over the workpiece rather than move the workpiece to the tool. The design of the radial drill press gives it a great deal of versatility, especially on parts too large to position easily. Radial drills offer power feed on the spindle, as well as an automatic mechanism to raise or lower the radial arm. The wheel head, which is located on the radial arm, can also be traversed along the arm, giving the machine added ease of use as well as versatility. Radial arm drill presses can be equipped with a trunion table or tilting table. This gives the operator the ability to drill intersecting or angular holes in one setup.Figure 3 Radial arm drill pressSPECIAL PURPOSE DRILL MACHINESThere are a number of types of special purpose drilling machines. The purposes of these types of drilling machines vary. Special purpose drilling machines include machines capable of drilling 20 holes at once or drilling holes as small as 0.01 of an inch.Gang Drilling MachinesFigure 4 Gang drill pressThe gang style drilling machine (Figure 4) or gang drill press has several work heads positioned over a single table. This type of drill press is used when successive operations are to be done. For instance, the first head may be used to spot drill. The second head may be used to tap drill. The third head may be used, along with a tapping head, to tap the hole. The fourth head may be used to chamfer.Multiple Spindle Drilling MachineThe multiple spindle drilling machine is commonly refered to as a multispindle drill press. This special purpose drill press has many spindles connected to one main work head (Figure 5).All of the spindles are fed into the workpiece at the same time. This type of drilling machine is especially useful when you have a large number of parts with many holes located close together.Figure 5 Multispindle drill pressMicro-Drill PressThe micro drill press is an extremely accurate, high spindle speed drill press. The micro drill press is typically very small (Figure 6) and is only capable of handling very small parts. Many micro drill presses are manufactured as bench top models. They are equipped with chucks capable of holding very small drilling tools.Figure 6 Micro drill pressTurret Type Drilling MachineTurret drilling machines are equipped with several drilling heads mounted on a turret (Figure 6). Each turret head can be equipped with a different type of cutting tool. The turret allows the needed tool to be quickly indexed into position. Modern turret type drilling machines are computer-controlled so that the table can be quickly and accurately positioned.Figure 6 CNC turret type drilling machine
What is the work done by a machine on a machine?
Power
Work performed on a machine?
The work done by a machine is called work output
For what is a core drilling used?
Core drills are used for several things such as when the core needs to be preserved or when the drilling can be done more rapidly because less material needs to be removed.
What is work done on a machine called?
Machine work
