Bu çalışmada, endüstri 4.0 uygulamalarında öne çıkan sıfır hata konseptine göre işparçasının işlenmesi sırasında düşük maliyetli kompanzasyon (telafi) metodu geliştirilmiştir. Yeni yöntem sayesinde, delik delme esnasında oluşan eksen hataları tespit edilmiş ve referans mastar blokları yardımıyla doğrulama faktörü bulunmuştur. Bu faktör kullanılarak, hata miktarı oranında nümerik kontrol (NC) kodları güncellenmiştir. Elde edilen sonuçlara göre, makine üzerine takılı ölçme probu yardımıyla doğru ve izlenebilir ölçüm yapılabildiği sonucuna ulaşılmıştır. Bu yöntemin düşük bir maliyet ile hassas parça imalatında kullanılabilir olduğu sonucuna varılmıştır. Delik mesafesi 500 mm için 55 μm olan tezgâhtan kaynaklanan eksen hatasının, yeni yöntemle ± 10 µm tolerans aralığında gerçekleştiği tespit edilmiştir. Kompanzasyon yöntemi yardımıyla eksen sapma değerleri %81 oranında iyileştirilmiştir.

Correction of Errors in CNC Machining Centers with a Work Based Approach

Öz

In this study, according to the zero defect concept that stands out in industry 4.0 applications, low cost compensation (compensation) method has been developed during the processing of the workpiece. Thanks to the new method, the axis errors that occurred during drilling were detected and the verification factor was found by using reference gauge blocks. By using this factor, numerical control (NC) codes have been updated at the rate of error. According to the results, it was concluded that accurate and traceable measurement can be made with the help of the measuring probe attached to the machine. It was concluded that this method can be used in precision parts manufacturing at a low cost. It has been determined that the axis error originating from the bench, whose hole distance is 55 μm for 500 mm, is realized in the tolerance range of ± 10 µm with the new method. With the help of compensation method, axis deviation values are improved by 81%.
