A model for productivity improvement on machining of components for stamping dies

Abstract

The production of stamping dies requires the manufacture of numerous components, many of which have similar dimensions. However, because they are almost all different, this brings added problems in the acquisition of materials, and in their machining, the main process used in the manufacture of these components. Most SMEs do not have production systems properly organized to manage the machining of these components in the most cost-effective way. The purpose of this work is to provide a novel tool able to re-organize the machining operations in the production of dies for stamping operations, saving time and allowing an easy way to extend the autonomous machining time. This work follows an empirical approach resulting from the experience and attempts to optimize machining operations in the production of stamping dies. A flowchart was developed, acting as guidelines to select if the set of parts to be manufactured can integrate the approach designed. The approach is validated by two case studies presented in the paper.

Selecting the best tools and framework to evaluate equipment malfunctions and improve the OEE in the cork industry

“…In view of the high competitiveness of the markets, industries need to show constant improvements and changes, whether in terms of their production systems or in terms of their equipment, thus seeking to keep their levels of competitiveness. To keep this competitiveness, companies must adopt continuous improvement measures to tackle all sources of waste in the production processes, and in the rest of the organization, with the objective of increasing profitability [1,2]. As such, the introduction of the Total Productive Maintenance (TPM) methodology allows organizations to make the most of their resources in an effective way, by eliminating losses, reducing breakdowns and, consequently, reducing costs.…”

Perancangan Hydraulic System Dalam Rangka Mendukung Dies Clamping Pada Mesin Press Seyi SN2-300 di PT Ganding Toolsindo

“…Pengumpulan dan pengambilan data di lakukan di PT Ganding Toolsindo yaitu mengamati secara langsung permasalahan yang ada pada perusahaan. Proses produksi satu komponen yang tidak efisien sudah cukup untuk membahayakan keseluruhan produk yang dimiliki komponen tersebut, masalah yang dihadapi adalah lamanya proses dalam pergantian baut pada saat setup dies [12] [13]. Hal tersebut dikarenakan proses dalam pergantian baut masih menggunakan cara yang manual.…”

Build-Up an Economical Tool for Machining Operations Cost Estimation

“…From a cost estimation standpoint, the selection of an adequate machining strategy for part production is crucial, requiring knowledge about the machining parameters and their influence [1,4]. A careful planning of the machining operations required for a determined part is very beneficial, for example, optimizing the material consumption for a set of operations, by grouping up similar shapes that require the same machining operation [17]. Correct operation sequence planning is also beneficial, especially when producing a series of parts.…”
