TITLE : WORKSHOP 1 FITTING INTRODUCTION In engineering bench work and fitting have important rules to play to complete and finish a job to the desired accuracy. The term bench work generally denates the production of our article by hand on the bench. Fitting is assembling together of part and remaining metals to secure the necessary fit, and may or be carried out at the bench.
Objective End of the session we should able to. Measure and mark file edge, file surface, file angle, hacksaw, drill hole, tapping in, punch the of work piece. Operate drilling machine post. Recognize the hand tools used in the fitting process. Learn how to use the vernier caliper for measuring. Read and interpret engineering drawing. Know basic workshop process. Inspect the job for specified dimensions. Adopt safety practices while working on various machines.

Safety precautions
The following safety precautions should be taken when using hand tools and equipment precautions are most important from accident. Before any work is carried out in the workshop, permission must be obtained from the workshop supervisor or lecturer. Always wear eye protection when using power operated hand or machine tools such as goggle. Work areas and equipment are to be thoroughly cleaned after use. Keep proper discipline in the workshop. Do not play with the tool because they are sharp. When using Hacksaw, check its teeth should be sharp and forward position. When using chisel its direction should be kept away from other working persons. When using Hacksaw check its blade with must be fitted in pins properly. Clean up oil and grease or other liquid which spills on the flour otherwise they may be a cause of accident. Do not wear any neck tie, jewel, rings, watches during in the working in shops. If last to leave the workshop, make sure all equipment are turned off.
PROCEDURES PROCEDURES Prepare mild steel piece follow measure that prescribed.
File two surface of the work piece to be 90` (measured by L-square)
Mark all dimension by using vernier height gauge
Cut the work piece which is not required by using hacksaw
Remove the work piece is not required using a chisel for part B
File all side of work piece to be 90`, it mean datum

PROCEDURES Mark the location of hole using center punch (A1,A2,B1,B2,C1,C2,C3,AND C4)
Drill hole according to the size of diameter required Using post drilling machine.
Cut the internal thread according to the size thread hole using hand tap
Remove the surface of the work piece as a process of finishing(thickness is 12 mm)

DISCUSSION
Cutting on the work pieces not straight? Solution : hold hack saw on proper way.Tilt the hack saw 45 °from the workpiece when cutting. Lack of accuracy on measurement? Solution : Make sure the surface of work piece flat when marking using angle plate and vernier height gauge.non flat surface will affect the measurement and also the shape. Work pieces not in required shape or not fit each other? Solution: Make sure the surface of work piece flat when marking using angle plate and vernier height gauge.non flat surface willaffect the measurement and also the shape.
8.0 CONCLUSSION On the end of this Fitting project we had learn how to use equipment and machine such as files, center punch, vernier height gauge and drilling machine. We also learned how to conduct a project and finish its report.we also know how to communicate each other to finish this project .we also learned the importance of fitting process in engineering field.
