MACHINING WORK Title: Perform machining according to standard operation procedure (SOP).
machine tool which spins a block of material to perform various operations such as cutting, sanding , knurling, drilling or deformation with tools that are applied to the work piece to create an object which has symmetry about an axis or rotation.
usually lathe is used in wood turning, metal working, metal spinning and glass working

The end of this project , student can learning: a) Practice safety procedures while operating the lathe and grinding machine. b) Grind tool bits (off hand grinding) according to the required geometric angles. c) Operate the lathe machine, select spindle speeds and feeds. d) Operate lathemachine for:
Parallel turning.
Stepped turning.
Facing.
Taper turning centre drilling.
Centre drilling.
Knurling.
e) Student can leaning to measure workpiece by using the following instruments.
Micrometer.
Vernier caliper
Steel ruler.
f) Keep the workshop clean and safe.

Safety glasses must be worn at all times in work areas.
Lathes often spit out chips and other pieces of hot, sharp metal. Wearing industrial safety glasses, especially those with side shields, will protect your eyes from damage.
Sturdy footwear must be worn at all times in work areas.
to protect your legs and feet from hot metal.
Close fitting/ protective clothing must be worn.
wear short sleeves or long sleeves with fitted cuffs that cannot get caught and drawn into the lathe

HOUSEKEEPING 1.
Switch off the machine and reset all guards to a fully closed position.
2.
Leave the machine in a safe, clean and tidy state.

DISCUSSIONS
This section analyze the result of the project. Project submitted expect no mistakes that can lose some or all of the marks. Project measured to obtain an accurate and precise measurements must be measured repeatedly during cessation of operation of the machine or restart the work back.
CONCLUSION
Conclusion, student can learn how to use lathe machine the right way,student can learn how to lathe operation the correctly and can learn new knowledge we never thinks in our minds to learn before this. Next,we know the types and uses of equipment in the process of lathe. Student can feel the fatigue and the pain suffered by the laborers building which we think is very simple to do. we should follow with any rules set by the lecturer. With the rules like house keeping, we can discipline our ownself and can be a useful man in the future. Next, while doing lathe process safety must come first in order to avoid the occurrence of unwanted injuries myself ... Lastly, I am very grateful because I can complete this lathe with successful,and complete workshop report.
