---------------------------------------------------------------------***--------------------------------------------------------------------1.2 Literature Review Abstract – This article describes the use of industrial Engineering techniques which improves productivity by minimizing scrap percentage. Implementing IE techniques (Automation, work-study, time study, layout design, operation study) to eliminate human intervention in order to reduce the scrap percentage. This leads to process improvement which resulted in a reduction of waiting time and lead time thereby increase in productivity.
1. According to the needs of the purchase department of the ABC Company, the plan and formulae were kept to be the same but the manual operations from the report were totally removed. As in apropos of VBA, literature was reviewed in the context of automation in MS Excel.
Key Words: Value stream mapping, Cause and effect diagram,3D-Scanner, Macro program, process chart,2^3 experiment.
2. Yakubu Yisa, in a 2^3 factorial experiment is designed to examine the influence of such factors as teaching method, gender, and level of study on students’ academic performance.
1. INTRODUCTION
3. Mario COCCIA, the fishbone diagram can be a comprehensive theoretical framework to represent and analyze the sources of innovation.
Productivity is a measure of economic performance that compares the number of goods and services produced by outputs with the number of inputs used to produce those goods and services. Scrap rate evaluates the number of goods companies produce that become waste because of defects or errors during manufacturing. The average productivity of the company was around 1.3 to 1.4lakhs and the average scrap rate is 29%. Powder metallurgy is one of the developing manufacturing techniques in which we can manufacture from small-size inserts to big-size dies and also it is an easy method to produce complex shapes in which some of the products do not need any secondary machining process to attain their shape and for some products secondary machining is required. The time consumption in the inspection was more, the Scrap rate was high (both in Green Carbide Inspection and Grinding).
4. Using an intrinsic function of our institution’s EMR, vital signs and lab results from 20 individual hospitalizations were exported to a spreadsheet.
2. Aims and Objectives Aim: To improve productivity by minimizing scrap rate using Industrial Engineering tools such as (Time study, process chart, simulation, fishbone diagram, Design of Experiments, and standard operating procedure). Objectives:
1.1 Problem Identification 1.
High scrap rate at the Sintering process due to manual calculation in the Green Carbide Inspection area and more time consumption for production.
Avoid errors by eliminating manual calculations and entries on route cards.
To reduce the waiting time for machine operators at green carbide inspection.
2.
Inappropriate Measuring Instruments lead to inaccurate measurements due to component sensitivity and brittle nature.
To obtain accurate measurements using a 3D scanner by providing the standard operation procedure.
3.
Inadequate monitoring and control in the grinding process (surface grinding) leading to poor quality of the finished workpieces
To ensure the integrity of the component and to prevent damage.
