“…The measurements were carried out using an optical profilometer (Talysurf CLI 2000; Taylor-Hobson, Leicester, Great Britain) equipped with laser triangulation sensor LK-031 (Keyence Corp., Osaka, Japan), which allowed measurements in the range of 10 mm at resolutions of 1 µm (vertical) and 30 µm (lateral). The description of the general view of the instrument is given in detail in the works of Guo et al [31], Elmas et al [32], and Kapłonek et al [33].…”

The condition of the cutting tool is one of the most important factors as it directly affects the technological and economic efficiencies of the woodworking process. The large variety of raw materials of wood combined with possible impurities and inclusion of solids puts high demands on planing machines. One of the methods to modify their operational properties is to apply antiwear coating on their working surfaces using vacuum deposition methods, such as physical vapor deposition (PVD). The use of such coatings reduces the adhesion of planing products to the surface of industrial planer knives, reduces the friction between the cutting tool and the workpiece, and limits the penetration of heat into the tool, thereby contributing to extending its effective working life. This study examines the impact of PVD-based CrCN/CrN coating on the operational durability and intensity of wear of planer knives operating in production conditions compared to unmodified knives (typically used in the wood processing industry for pine wood planing). For the unmodified and CrCN/CrN-coated planing blades (before and after processing), detailed analyses were carried out. These analyses included determining the rounding radius and profile along the blade (worn edge displacement), calculating surface texture parameters of the rake face of planer knives, and carrying out visual microscopic analysis of its condition. The results of the experiments indicated an increase in durability of up to 142% for the CrCN/CrN-coated tools. It was also found that the use of PVD-based modified industrial planer knives turned out to be more beneficial in each analyzed area of analysis.

“…The family of multisensory optical profilometers Talysurf CLI (Chromatic, Laser, Inductive) produced by British company Taylor-Hobson has been very popular on the global market for several years [22]. In the years 2003-2004, a new class of those type of instruments, designated CLI 500, CLI 1000 and CLI 2000, respectively was introduced.…”

The term optical profilometry is used in relation to a group of methods used in a rapid, non-destructive, and non-contact assessment of surface topography. Those methods play a significant role in the area of a modern advanced laboratory and industrial 3D measurements. With the development of profilometric methods, a large progress in the construction of optical profilometric instruments and measuring sensors used in them, including confocal sensors based on the chromatic light aberration phenomenon (CLA) has been observed for several years. The paper shows that the Talysurf CLI 2000 multisensory optical profilometer equipped with a CLA sensor can be used in high-accuracy 3D measurements of the uncirculated and circulated coins. The assessment of such type objects characterized by a high variability of altitude can be extremely helpful in analyzing the actual metrological properties of measuring equipment used in their measurements.

ÖZETEğimli yüzeylerin küresel parmak frezelenmesinde, değişken yüzey formu kesici takım üzerinde değişken kesme kuvvetlerine neden olmaktadır. Kesme kuvvetleriyle oluşan esnemeler parça üzerinde göz ardı edilemeyecek form hataları oluşturabilmektedir. Sehim değerlerinin ve buna bağlı form hatalarının bulunması, üretim için uygun toleranslar içinde kalınması ve maliyetlerin azaltılması açısından önem taşımaktadır. Çalışmada EN X40CrMoV5-1/DIN 1.2344 sıcak takım iş çeliğinin TiAlN kaplamalı küresel kesici ile dışbükey ve içbükey yüzeylerin frezelenmesinde takım sehimine bağlı form hatalarını değerlendirilmesi hedeflenmiştir. Farklı takım yolu stratejileri ve kesme parametrelerinin ilgili parametre seviye aralıklarında deneyler gerçekleştirilmiştir. Deneylerde endüktif sensörler ile işleme süresince dinamik takım sehimi kaydedilmiştir. 3B optik tarama ile işlenen deney numunelerin takım sehimine bağlı form hataları tespit edilmiştir. Ölçülen takım sehim değerleri ve 3B optik tarama form hata ölçüm değerleri karşılaştırılmıştır. Dışbükey ve içbükey yüzey formları için tırmanma bölgelerinde, frezeleme pozisyon açısının 45º ile 60º aralığında en fazla takım sehimi ve form hatası tespit edilmiştir. Aynı zamanda, en büyük sehimin oluştuğu bölgeler, optik taramalardan elde edilen en büyük form hata bölgelerinin olduğu gözlemlenmiştir. Çalışma sonucunda, kesici takım sehiminin neden olduğu form hatalarının tespitinde, dinamik ölçümlerinden elde edilen değerlerin optik tarama sonucunda elde edilen form hataları ile örtüştüğü görülmüştür.Anahtar kelimeler: Eğimli yüzeyler, küresel parmak frezeleme, takım sehimi, form hatası, optik tarama DETERMINATION OF FORM DEFECTS DEPENDING ON TOOL DEFLECTION IN BALL END MILLING OF CONVEX AND CONCAVE SURFACES ABSTRACTAltering in surface forms cause to varying cutting forces in machining of inclined surfaces by ball end mills. The deflections appeared by cutting forces can result in form defects in workpiece. Finding deflection values and related form defects has a significant importance for keeping the production within the appropriate tolerances and in lessening production costs. The aim of this study is to evaluate form defects depending on tool deflection in milling of inclined convex and concave surfaces of EN X40CrMoV5-1/DIN 1.2344 using TiAlN-coated cutting tool. The experiments have been conducted with different cutting tools strategies and cutting parameters at related parameter levels. During machining real time cutting tool deflections are recorded by inductive sensors for the experiments. Then, the form defects of machined specimens caused by cutting tool deflections are determined by 3D optical scanning. The cutting tool deflection values and the values of 3D optical scanning form defects have been compared. The largest cutting tool deflections and form defects are detected at the ramping regions with the milling position angles of 45º to 60º for the convex and concave surface types. In addition, the regions that the largest tool deflections have been observed are the same re...
