Tolerans teknikleri ve tolerans analizi: Yapılan çalışmaların değerlendirilmesi

İmalat işlemlerinin planlanmasındaki en önemli hususlardan biri, genellikle minimum üretim maliyeti, minimum bozuk parça miktarı ve maksimum toplam işleme toleransları gibi gerekli bir üretim hedefinin elde edilmesiyle optimize edilen "proses toleransları"nın tasarımıdır. Üretilen parçanın boyutlarındaki toleransın belirlenmesi, nihai ürün maliyeti üzerinde önemli bir etkiye sahiptir. Son yirmi yılda, toleranslandırma teknikleri alanında pek çok çalışma yapılmıştır. Bu makalede, elde edilebilecek gelişmiş teknikleri tanımlamak ve gelecekteki araştırmalara kılavuzluk etmek amacıyla bu çalışmaların karşılaştırmalı bir özeti ile toleranslandırma teknikleri ve tolerans analizinde gelecekteki eğilimlerin bir projeksiyonu sunulmuştur. Bu amaçla, literatürdeki 30'dan fazla makale üç kategoride sınıflandırılmak suretiyle değerlendirilmiştir. Bu sınıflandırma; boyutsal tolerans zinciri tekniği, toleranslarda geometrik modelleme ile toleranslandırmada istatistiksel ve ihtimal metotlarını kapsamaktadır.

Tolerancing techniques and tolerance analysis: A review of previous studies

One of the important tasks in the planning of a manufacturing process is the design of process tolerances which are usually optimized by achieving a required production objective, such as the minimum manufacturing cost, scrap rate and the maximum total process tolerances. The specification of tolerancing on the dimension of the manufactured part has a significant impact on the final production cost. In the last two decades, several works have been done in the area of tolerance techniques, hi this paper a comprehensive summary of these studies and the projection of future trends in tolerancing techniques and tolerance analysis presented to describe improved techniques available today and to aid in guiding research for the future. For this aim, more than 30 papers in the literature have been evaluated by classifying into three categories. This classification includes the dimensional tolerances chain technique, geometrical modelling in the tolerances and statistical and probabilistic methods in tolerancing.
