to reduce the energy loss due to frictional force.
because machine want lubrication with out lubrication machine parts will be damaged
To prevent the friction between them otherwise they will jam and there may be excess heating of parts due to frictionAnother reason to oil machine parts is to prevent rusting. IF a machine part is rubbing another so one has bare metal - it will rust quite quickly - so in addition to reducing friction and heat build up it prevents rust
Adding oil to the moving parts of machines can do that because it makes it smoother and takes the rust off of it.
It can be used on the moving parts inside where no thread goes.
To oil a Singer Simple sewing machine, first unplug it and remove the needle and presser foot. Use a small brush to remove any lint or debris from the machine. Apply a drop of sewing machine oil to the moving parts indicated in the manual, such as the shuttle hook or bobbin case. Run the machine on a scrap piece of fabric to distribute the oil. Wipe off any excess oil and reassemble the machine.

Lubricating oil is applied to moving parts of a machine to reduce friction, which helps prevent wear and tear on the components. It also helps dissipate heat, improve efficiency, and extend the lifespan of the machine by reducing mechanical stress.
Regular oil and filter changes extends the life of the bearings and all moving parts.
Oil and grease can reduce the amount of friction, making it easier for parts to slide against one another, and reducing the amount of heat produced.
The engine oil helps in lubricating the machine. Oil helps in cooling the engine and lubricates the moving parts properly. The moving parts are constantly shifting and are connected to each other. Oil is needed to grease the parts so that the components move properly without causing harm to the machines.
Friction. It can be reduced by lubricating substances such as oil.
