Abstract

With this article, hand-arm vibration, and related physical stresses of those working in casting grinding work in a foundry were investigated. The aim of the study is to determine the vibration value transmitted to the hands and arms of the worker with the grinding tool during the grinding of cast parts by measuring during one shift and to produce solutions for reducing high vibration values. For this purpose, with reference to the methods specified in the TS EN 5349 standard for grinding operators, measurements were made on 21 cast part grinding operators in five different grinding processes. Measurements were performed in the right hand over. Values ranging from 1.79 m/s² to 95.69 m/s² were obtained for 8 hours of exposure in cast iron workers. The highest values are A(8)=95.69 m/s2 when cleaning the holes of the motor block part connected to the rotator with an air hammer, A(8)=20.43 m/s2 when grinding on a fixed machine and in the final grinding process A(8)=12.76 m/s2 was obtained. According to the results of the research, in order to reduce hand-arm vibration exposures, it should be aimed to reduce the surfaces that require grinding with engineering work in the cast part. The formation of burrs originating from the core sand on the core surfaces that form the voids in the cast part should be prevented and the problem should be eliminated at the source by using high-strength cores for the holes clogged with sand that can be opened with an air gun.

Abstract

Bu makale ile bir dökümhanede döküm parça taşlama işinde çalışanların el-kol titreşimi ve ilgili fiziksel stresler araştırılmıştır. Çalışmanın amacı döküm parçaların taşlanması sırasında taşlama aleti ile çalışanın el ve kollarına iletilen titreşim değerinin bir vardiya boyunca ölçülerek tespit edilmesi ve yüksek titreşim değerlerinin azaltılması için çözümler üretilmesidir. Bu amaçla taşlama operatörlerinde TS EN 5349 standartında belirtilen metodlar referans alınarak 21 döküm parça taşlama operatörü üzerinde, beş değişik taşlama işleminde ölçümler yapılmıştır. Ölçümler sağ elde bir vardiya boyunca uygulanmıştır. Döküm parça taşlama yapan çalışanlarda 8 saatlik maruziyet için 1,79 m/sn² ile 95,69 m/sn² arasında değişen değerler elde edilmiştir. En yüksek değerler döndürücüye bağlı motor blok parçasının deliklerindeki temizlik işlemini havalı çekiç ile yaparken A(8)=95,69 m/s2, yere sabit bir makinada yapılan taşlama işleminde A(8)=20,43 m/s2 ve final taşlama işleminde A(8)=12,76 m/s2 elde edilmiştir. Araştırma sonuçlarına göre el-kol titreşim maruziyetlerinin azaltılması için öncelikle döküm parçada mühendislik çalışması ile taşlama gerektiren yüzeylerin azaltılması amaçlanmalıdır. Döküm parçada boşlukları oluşturan maça yüzeylerindeki maça kumu kaynaklı çapakların oluşması engellenmeli ve havalı tabanca ile açılabilen kum ile tıkalı delikler için dayanımı yüksek maça kullanılarak problem kaynağında giderilmelidir.
