Cumulative Average Pricing Method For Estimating Average Service Life, Mahendra Babu Hosangadi
Cumulative Average Pricing Method For Estimating Average Service Life, Mahendra Babu Hosangadi
Masters Theses
The study determined if accuracy of estimation of retirement price of industrial equipment was affected by using a cumulative average pricing (CAP) method at varying conditions of inflation rate, service life, and life characteristics. The study also determined the accuracy of estimating the average life of unaged data by simulated plant record (SPR) method. Thirty-six experiments were conducted at varying conditions of inflation rate, curve type and average life. The study was conducted for two left modal curves, two symmetrical modal curves and two right modal curves at 20 and 40 years average life using three different inflation rates: 3%, …
Addition Of Automatic Dimensioning Feature To D-M-E’S Ultimate Mold Base Design Software, Cori L. Brown
Addition Of Automatic Dimensioning Feature To D-M-E’S Ultimate Mold Base Design Software, Cori L. Brown
Masters Theses
There have been many improvements in the plastics industry over the past few years. One of these areas is in the design of injection molds. This area has been enhanced by the use of Computer-Aided Design systems and furthered by the creation of specialized mold design software. The Ultimate® design system from D-M-E has made a mold designer's job much easier by automating much of this process. This project extends the function of this software by adding an automatic dimensioning feature that will make the mold design process less tedious and less time consuming. This addition will also standardize …
Development Of A Mold Trial Procedure For Establishing A Robust Process, Marc R. Vander Kooi
Development Of A Mold Trial Procedure For Establishing A Robust Process, Marc R. Vander Kooi
Masters Theses
To reduce variation in the injection molding process it is essential to understand the effect of process, mold, and material variables on critical part characteristics. Gaining a thorough understanding of these variables is often difficult due to the limited time manufacturers typically have available for mold trials. To address this issue, the Premier Class Injection Molding consortium (PCIM) has performed numerous experiments relating to shot-to-shot repeatability. Using the PCIM data set and experimentation procedures as a base, a procedure was developed to collect data during a mold trial. Incorporating small experiments and statistical analysis, the new procedure allows meaningful data …
