MACHINING WORK

Title: Perform machining according to standard operation procedure (SOP).

Introduction 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

TAKS OUTCOME

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 precautions

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.

Procedures

1) grind the tool right up sharp

Prepare work piece o30mm x 100mm

1) Clamp and face one side 2) Turn to o23mm x 100mm3) Turn to o16mm x 35mm at on side 4) Set to 6 angle5) Cut a 6 angle x 45mm6) Chamfer all shape edges/corner height (C1)7) Make a knurled surface along 20mm8) Chamfer all shape edges/corner height (C1)

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.
