A Phased Approach to Optimized Robotic Assembly for the 777X

Boeing Co.-Ryan Mir
Electroimpact Inc.-Russell DeVlieg
Published 2019-03-19 by SAE International in United States
Low rate initial production of the 777X flight control surfaces and wing edges has been underway at the Boeing St. Louis site since early 2017. Drilling, inspection, and temporary fastening tasks are performed by automated multi-function robotic systems supplied by Electroimpact. On the heels of the successful implementation of the initial four (4) systems, Phases II and III are underway to meet increasing production demands with three (3) and four (4) new cells coming online, respectively. Assemblies are dedicated to particular cells for higher-rate production, while all systems are designed for commonality offering strategic backup capability. Safe operation and equipment density are optimized through the use of electronic safeguards. New time-saving process capabilities allow for one-up drilling, hole inspection, fastening, fastener inspection, and stem shaving. Multi-function end effectors with dual spindles permits drilling and reaming within a single clamp, and hybrid cutting fluid delivery enables a no-compromise approach to process optimization. New automated health checks and calibrations limit the need for operators and maintenance personnel to access the equipment. The integration of these innovative technologies…

The project of lean management is implemented in General Motors India Private Limited, Pune, India plant. The aim of the project is to improve manpower utilization by removing seven types of wastes using lean management system in kitting process. Lean manufacturing or management is the soul of Just-In-Time philosophy and is not new in Automobile manufacture sector where it born. Kitting area is analogs to the modern supermarket where required components, parts, consumables, subassemblies are kept in bins. These bins are placed in racks so that choosing right part at right time can be achieved easily. Video recording, in-person observation, feedback from online operators and other departments such as maintenance, control, supply chain etc. are taken. It is observed that the work content performed by current strength of operators can be performed by less number of operators. After executing this project, it was possible to reduce one operator and increase manpower utilization. Continuous improvement is a part of lean management the organization is striving for it.

Optical Bonding of Automotive Smart Surfaces

  • Magazine Article
  • TBMG-28340
Published 2018-02-01 by Tech Briefs Media Group in United States

Behr Hella Thermo Control (BHTC) of Lippstadt, Germany, manufactures automotive interior components. As the demand for smarter cars increases, BHTC encountered a new automotive interior challenge: optical bonding of automotive smart surfaces. The challenge of optical bonding led to a working relationship with Precision Valve and Automotive (PVA) of Cohoes, NY, to meet BHTC’s production and flexibility needs.

Published 2017-07-10 by SAE International in United States
Lean approaches are being implemented in various manufacturing facilities across the globe. The application of lean approaches are extended to Body proto build shop to maximize the efficiency of the shop with lesser floor space and optimized equipment. Weld fixture, Weld equipment and assembly tools are the major tools required essentially for proto BIW assembly. This paper explains how the Weld equipment planning was carried out with lean approaches and implemented effectively in proto body assembly shop. The implemented lean concepts are compared with Italy and Japanese proto body build makers to validate the frugal planning of the facility for the said intent. The implemented facility is capable of producing more than a model at a time. Weld parameter selection for weld gun, gun movement to the fixture with minimized change over time and movable weld gun gantry are the lean approaches implemented.

Supplier Quality Engineering and Lean Manufacturing Integration

MWM Navistar Company-Silvio César Bastos
Published 2017-03-28 by SAE International in United States
Automotive industries have been seeking quality excellence as a key factor in competitiveness. Product characteristics and functions should meet the expectations of customers in terms of warranty and reliability.The objective of this paper is to present a method to improve the synchronization of customer’s product requirements with their suppliers in terms of key performance indicators.The improvement allows suppliers to take corrective and preventive actions through knowledge of component applications in engines and vehicles.Engine assembly lines maintain records and meet daily meet to explore trends of productivity, and supplier quality performance is measured based on engine failure instead of parts supplied.This methodology integrates Lean Manufacturing and Supplier Quality Engineering and respective targets, combining efforts towards Quality Assurance.

In an SAE International technical paper, students at the University of Idaho identify best practices for their SAE Clean Snowmobile Challenge team.

THE UNIVERSITY OF IDAHO Clean Snowmobile Challenge (UICSC) team has been competing since 2001 in the SAE International Clean Snowmobile Challenge (CSC). Typically, the team will have 10-15 members, with as many as two-thirds of the members returning from the previous year. The team includes students from all four years of the undergraduate engineering program along with one or two graduate student mentors. Membership is predominantly mechanical engineers, but the team usually has at least one electrical engineer in addition to a number of students from other disciplines.

Study of Lean Production System Using Value Stream Mapping in Manufacturing Sector and Subsequent Implementation in Tool Room

Delhi Technological University-Rushil Batra, Sahil Nanda, Shubham Singhal, Ranganath Singari
Published 2016-04-05 by SAE International in United States
This research is an attempt to investigate the significance of Value Stream Mapping (VSM) in the lean transformation of manufacturing units (largely automotive) and then apply the same in a tool room. It is an essential tool used to interpret both material and information flow in a system. The tool room under study specializes in production of a large variety of high precision tools for the automotive industry. A product family is chosen to map and analyze various stages of its production process, starting from the raw material (R/M) to the finished goods’ (F/G) stage. VSM is then implemented in the tool room to correctly identify wastes and thus improvement areas to bridge gaps between current and future states. Both current and future state maps are drafted along with usage of other lean tools to justify its implementation in a small setup like tool room. Given the customized nature of work being performed in the setup, task standardization is not a priority but employee specific tasks are suggested after optimization of all work procedures. Methods…
