									<p data-start="836" data-end="1458">The ability to accurately characterize tooth surfaces, including micro-roughness and 3D surface topography at the nanometer scale, enables advanced research and applications in orthodontics and dental materials science. Non-contact optical profilometry provides a precise method for measuring dental surface roughness and analyzing tooth surface morphology without damaging delicate structures. These measurements support the development of composite dental materials that replicate the natural surface roughness of enamel, as well as the design and fabrication of patient-specific dental casts and restorative components.</p><p data-start="1460" data-end="1982">Low surface roughness plays a primary role in limiting bacterial adhesion and plaque formation, thereby reducing the risk of cavities. An increase in average roughness (Ra) above 2 µm leads to a steep increase in biofilm formation in vivo.¹ An Ra of 0.2 µm is considered the threshold value below which no further reduction in bacterial adhesion can be expected.²</p><p data-start="1984" data-end="2182">Reconstruction of the tooth’s 3D surface topography enables the fabrication of dental casts, which are essential for accurate diagnosis, treatment planning, and the fabrication of dental appliances.</p>								</div>

It acquires data points from deep crevices and complex geometries without introducing measurement errors or artifacts caused by local plastic deformation and without requiring extensive data manipulation.</p><p data-start="715" data-end="1135">Compared to focus variation systems, single-point optical sensing provides superior lateral and height accuracy, with X/Y resolution below 0.5 µm, maximum vertical resolution of 1.9 nm, and the ability to measure surface angles up to 87°.

									<p>파면분석(Fractography)은 파손된 표면의 특징을 연구하는 것으로 역사적으로 현미경이나 SEM을 통해 조사되어 왔습니다. 피처의 크기에 따라 표면 분석을 위해 현미경(매크로 피처) 또는 SEM(나노 및 마이크로 피처)이 선택됩니다. 두 가지 모두 궁극적으로 파손 메커니즘 유형을 식별할 수 있습니다. 비록 효과적이긴 하지만 현미경은 명확한 한계를 가지고 있으며 원자 수준 분석을 제외한 대부분의 경우 SEM은 파손 표면 측정에 실용적이지 않으며 광범위한 사용 기능이 부족합니다. 광학 측정 기술의 발전으로 NANOVEA는 <a href="https://nanovea.com/profilometers/">3D 비접촉 프로파일로미터</a> 이제 거시적 규모의 2D 및 3D 표면 측정을 통해 나노를 제공할 수 있는 능력을 갖춘 최고의 장비로 간주됩니다.</p>								</div>

									<p>벨트 구동 기계의 벨트는 마찰과 마모가 불가피합니다. 충분한 마찰은 미끄러짐 없이 효과적인 동력 전달을 보장하지만 과도한 마찰은 벨트를 빠르게 마모시킬 수 있습니다. 벨트 구동 작동 중에는 피로, 마모, 마찰 등 다양한 유형의 마모가 발생합니다. 벨트의 수명을 연장하고 벨트 수리 및 교체에 드는 비용과 시간을 절감하기 위해서는 벨트의 마모 성능을 신뢰성 있게 평가하여 벨트의 수명, 생산 효율성 및 응용 분야 성능을 개선하는 것이 바람직합니다. 벨트의 마찰 계수 및 마모율을 정확하게 측정하면 벨트 생산의 R&amp;D 및 품질 관리가 용이해집니다.</p>								</div>

									<p>이 연구에서는 벨트의 마찰 계수와 마모율을 잘 제어되고 정량적인 방식으로 평가할 수 있는 나노베아 T2000 트라이보미터의 성능을 보여주었습니다. 표면 텍스처는 벨트의 서비스 성능 중 마찰 및 내마모성에 중요한 역할을 합니다. 텍스처가 있는 벨트는 마찰 계수가 0.5 정도로 안정적이며 수명이 길기 때문에 공구 수리 또는 교체에 드는 시간과 비용을 절감할 수 있습니다. 이에 비해 매끄러운 벨트와 스틸 볼의 과도한 마찰은 벨트를 빠르게 마모시킵니다. 또한 벨트에 가해지는 하중은 벨트의 수명을 결정짓는 중요한 요소입니다. 과부하는 매우 높은 마찰을 발생시켜 벨트의 마모를 가속화합니다.</p>

					<description><![CDATA[<p>FOSSIL MICROSTRUCTURE USING 3D PROFILOMETRY Prepared by DUANJIE LI, PhD INTRODUCTION Fossils are the preserved remains of traces of plants, animals and other organisms buried in sediment under ancient seas, lakes and rivers. The soft body tissue usually decays after death, but the hard shells, bones and teeth fossilize. Microstructure surface features are often preserved [&#8230;]</p>

									<p>표면 특징, 패턴, 모양 등의 인터페이스를 방향에 대해 평가하는 연구에서는 전체 측정 프로파일에서 관심 영역을 빠르게 식별하는 것이 유용합니다. 표면을 중요한 영역으로 세분화하면 경계, 피크, 구덩이, 면적, 부피 등을 빠르게 평가하여 연구 중인 전체 표면 프로파일에서 기능적 역할을 이해할 수 있습니다. 예를 들어 금속의 입자 경계 이미징과 같이 분석에서 중요한 것은 많은 구조의 인터페이스와 전체적인 방향입니다. 각 관심 영역을 이해함으로써 전체 영역 내의 결함 또는 이상을 식별할 수 있습니다. 입자 경계 이미징은 일반적으로 프로파일로미터 기능을 능가하는 범위에서 연구되며 2D 이미지 분석에 불과하지만, 3D 표면 측정의 장점과 함께 더 큰 규모로 표시되는 개념을 설명하는 데 유용한 참고 자료가 됩니다.</p>								</div>

									본 애플리케이션에서는 NANOVEA 3D 비접촉 광학 프로파일러가 타이어 트레드 깊이, 윤곽 치수 및 고무 표면 거칠기를 정밀하게 특성화하는 방법을 보여주었습니다. 데이터에 따르면 표면 거칠기는 2.69 µm, 전개 면적은 9.41 mm²이며 투영 면적은 9 mm²입니다. 고무 트레드의 다양한 치수와 반경도 측정되었습니다. 이 정보는 타이어 제조사, 자동차 연구원 및 재료 엔지니어가 트레드 설계, 고무 배합 또는 다양한 마모 정도를 가진 타이어를 비교하는 데 활용될 수 있습니다. 여기에 제시된 데이터는 Ultra 3D 분석 소프트웨어에서 가능한 계산의 일부만을 나타냅니다.								</div>

					<description><![CDATA[<p>INTRODUCTION &#160; Having precise dimensions and optimal surface roughness are vital to the functionality of dental screws. Many dental screw dimensions require high precision such as radii, angles, distances, and step heights. Understanding local surface roughness is also highly important for any medical tool or part being inserted inside the human body to minimize sliding [&#8230;]</p>

<h2><em><strong>소개</strong></em></h2>
<p>&nbsp;</p>
<p>정확한 치수와 최적의 표면 거칠기를 갖는 것은 치과용 나사의 기능에 매우 중요합니다. 많은 치과용 나사 치수에는 반경, 각도, 거리, 계단 높이 등 높은 정밀도가 필요합니다. 미끄러지는 마찰을 최소화하기 위해 인체 내부에 삽입되는 의료 도구나 부품의 경우 국부적인 표면 거칠기를 이해하는 것도 매우 중요합니다.</p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<h2><em><strong>차원 연구를 위한 비접촉 프로파일 측정</strong></em></h2>
<p>&nbsp;</p>
<p>나노베아 <a href="https://nanovea.com/profilometers/">3D 비접촉 프로파일러</a> 유채색광 기반 기술을 사용하여 투명, 불투명, 반사, 확산, 광택 또는 거친 재료 표면을 측정합니다. 터치 프로브 기술과 달리 비접촉 기술은 좁은 영역 내부를 측정할 수 있으며 팁이 부드러운 플라스틱 재료를 눌렀을 때 발생하는 변형으로 인해 본질적인 오류가 추가되지 않습니다. 또한 색광 기반 기술은 초점 변형 기술에 비해 뛰어난 측면 및 높이 정확도를 제공합니다. Nanovea Profilers는 스티칭 없이 직접 큰 표면을 스캔하고 몇 초 안에 부품 길이의 프로파일을 생성할 수 있습니다. 결과를 조작하는 복잡한 알고리즘 없이 표면을 측정하는 프로파일러의 기능으로 인해 나노부터 매크로 범위의 표면 특징과 높은 표면 각도를 측정할 수 있습니다.</p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<h2><strong><em>측정 목표</em></strong></h2>
<p>&nbsp;</p>
<p>이 응용 분야에서는 Nanovea ST400 광학 프로파일러를 사용하여 단일 측정으로 평면 및 나사산 형상을 따라 치과용 나사를 측정했습니다. 평평한 면적으로부터 표면 거칠기를 계산하고 나사산 형상의 다양한 치수를 결정했습니다.</p>
<p>&nbsp;</p>

<h6 class="mceTemp" style="text-align: center;"><i>치과용 나사 샘플이 분석되었습니다.</i></h6>
</div>
<p>&nbsp;</p>
<h2><em><strong>결과</strong></em></h2>
<p>&nbsp;</p>
<p><strong><em>3D 표면</em></strong></p>
<p>치과용 나사의 3D 보기 및 가색상 보기에는 나사산이 양쪽에서 시작되는 평평한 영역이 표시됩니다. 이는 사용자에게 다양한 각도에서 나사의 형태를 직접 관찰할 수 있는 간단한 도구를 제공합니다. 표면 거칠기를 측정하기 위해 전체 스캔에서 평평한 영역을 추출했습니다.</p>

<p>&nbsp;</p>
<p><em><strong>2D 표면 분석</strong></em></p>
<p>나사의 단면도를 표시하기 위해 표면에서 선 프로파일을 추출할 수도 있습니다. 윤곽 분석 및 계단 높이 연구를 사용하여 나사의 특정 위치에서 정확한 치수를 측정했습니다.</p>
<p>&nbsp;</p>

<h2><em><strong>결론</strong></em></h2>
<p>&nbsp;</p>
<p>이 응용 프로그램에서는 단일 스캔으로 국소 표면 거칠기를 정확하게 계산하고 큰 차원 특징을 측정하는 Nanovea 3D 비접촉 프로파일러의 기능을 선보였습니다.</p>
<p>데이터는 0.9637μm의 국부적인 표면 거칠기를 보여줍니다. 나사산 사이의 나사 반경은 1.729mm로 나타났으며, 나사산의 평균 높이는 0.413mm로 나타났다. 나사산 사이의 평균 각도는 61.3°로 결정되었습니다.</p>
<p>여기에 표시된 데이터는 분석 소프트웨어에서 사용할 수 있는 계산의 일부에 불과합니다.</p>
