Also, a lack of rock mechanics knowledge can prevent the most efficient solution being applied. Some operators are implementing planning programs that assess and integrate the latest processes and technologies to address drilling risks up-front. Cutting-edge technologies such as managed pressure drilling methods, drilling with casing drilling with liners, and solid expandable casing have been highly effective. Implementing proactive evaluation processes and applying the latest tools and techniques can efficiently address operational risks and trouble zones to ultimately reduce NPT and associated costs. Keywords: Npt1, Productive time(PT)2, Theoretical Time3, Non Machining Time4, Machining Time5 etc.. Introduction AREA OF CASE STUDY :- PRODUCTIVE AND NON PRODUCTIVE TIME OF MACHINING. Our area of case study is sequence of operations performed on job. Productive time required for each operation and also finding nonproductive time(NPT) Objective Of Case Study 1 The objective of case study is to study the actual machining time and to compare it with theoretical time .To study the actual time required for operations performed and also productive and nonproductive time. And to determine scope for reduction of non productive time to increase productivity and to compare the actual machining procedures with theoretical concept. Problem Identification2 1) Time difference between theoretical time required for the completion of job and actual time required . 2) Non productive. We study the theoretical time required for each operation performed on job and actual time required. The time loss in handling material, waiting situations due to previous operation . time taken by workers. Loading of job on lathe or any other machines etc. Elaboration Of Problebs2 EN-8 round bar records its machining time required in actual process and theoretical time required ,to find time losses in nonproductive time & productive time. Fig-1 EN-8 Round Bar All the activities were then recorded on a flow process sheet and have been summarized by the team. The non-productive time for each of the above work centers was calculated.
