Productivity Improvement through Cycle Time Reduction and Line Balancing: A Case Study of Machine Shop

Competitiveness among the manufacturing industries is rapidly increasing because of industrialization. In today’s era, every manufacturing industry is trying to produce low cost products with superior quality and with propriety to deliver them in stipulated time period. Every manufacturing organisation needs appropriate system to produce high quality products in minimum cycle time, which can be achieved by maintaining higher productivity. In this research study, an attempt has been made to enhance the productivity of automotive component oil pan by reducing the machining cycle time and balancing the line to avoid unwanted movement of work piece and bottlenecks. It has been found that by incorporating CBN cutters and spot facing tool in machining, cycle time has been reduced by 7.02minutes per job. U type machine layout has been suggested to balance the production line.It has been observed that, with reduction of cycle time by 7.02 minutes per job, production capacity per shift can be increased from current 28 jobs per shift to 36 jobs per shift. With machining of additional 8 jobs per shift, production capacity of oil pan can be increased from 2000 jobs per month to 2900 jobs per month.

Development of High-Efficient, Resource-Saving Technical Solutions for Wastewater Treatment in Galvanochemical Sector

This article presents the results of the analysis of samples of a machine-shop for the content of organic components and heavy metal ions. The proposed modernized technological scheme uses modern technological solutions for a machine-shop. Based on the analysis of sites and sewage treatment plants of galvanic production, as well as analysis of the presence of polluting components, technical solutions, which are going to increase the intensification and efficiency of water treatment and water treatment through the use of modern physical and chemical methods, technological methods and wastewater treatment devices have been developed. The introduction of additional sorption modules with activated carbon will reduce the ingress of toxic organic components (DBP, aniline, solvents: acetone, gasoline, ethyl acetate, polymer epoxy compounds, including: epoxy adhesives, polymer filler, epoxy-phenolic, phenolic-rubber and rubber adhesives, release adhesives) into wastewater. A modernized scheme using modern solutions will comply with Mosvodokanal standards. Keywords: wastewater, water treatment, toxic organic components, heavy metal ions
