Third category of the table is Hammering, Hammering is the main operation of the forging as the power hammer is
dropped and the shape and size of the product is changed, so by the calculations 5 % of the postures are in the low level risks ,
65% are in the medium level risks and rest 18.8% is under high risk. Investigations are required for all level of risks and changes
are to be done according to the need. Further comes the process of the Punching and Trimming as from the table is that 52% is
of medium level risks, 42% is of high level risks and remaining 2.6% is very high risk. Next is Grinding and Drilling 50% is
medium level, 42.8% is high risks and 7% is very high risks, scope of improvement is always there so changes are to be made.
Whereas in the next category broaching, chamfering and heat treatment there is only 28% of low level and 71% of medium
risks as there is no high risks in these processes. Inspection is the most important aspect of any field which determines the
quality of the product. but during there is always posture failures as no low level, 75% is of high level and 25% is of very high
risks. Then comes the material handling or Picking and placing, in this category postures calculations are 6% of low level risks,
33% of medium and 48% of high risks and 13% is very high level risk. Investigations are to be made for better material
handling methods. Last category of the table is Lathe and Welding. In this processes there is also scope of improvement as
calculated as 77% of medium level risks and 22% of high risks are involved. As mentioned in the above processes examinations
are to be made to check whether the methods can be improved to reduce the load on the worker and he could perform his duties
with full efforts. Table-2 shows the No. of posture with REBA score in each section and. No. of posture left hand and right hand
with percentage and risk level shown in Table-3.
