Abstract This paper presents an experimental study to assess the effects of physical and mechanical properties of carbonate rocks and diamond/metal matrix characteristics on performance and tool life of segmented circular sawblades. For this purpose, pertinent rock properties including strength, hardness, abrasivity, water absorption, porosity and unit weight were measured by laboratory tests and compiled into a database for subsequent analysis. The testing program including using six commercially available sawblades with different segment compositions in full scale tests. The related characteristics of the sawblades were diamond concentration, Vickers hardness of the hard facing matrix, mean diamond grain size, cobalt, tin, copper, and ferrous content. Thirteen different carbonate rocks including marble, limestone, and travertine samples from various sites in Turkey were used in the experimental program. The experimental data was analysed by multiple linear and nonlinear regression analysis to develop models for estimation of specific energy (SE) and specific wear (SW) rates using rock properties and sawblades segment parameters. The proposed models were validated by comparing the results of their prediction with those of actual test results and showed good agreements. The concept of optimum total (cutting) cost (OTC) estimation for natural stone cutting is also discussed in the context of estimating sawblade wear life.

摘要 本文提出了一项实验研究，以评估碳酸盐岩的物理和机械特性以及金刚石/金属基体特性对分段圆锯片的性能和刀具寿命的影响。为此，通过实验室测试测量了相关的岩石特性，包括强度、硬度、磨蚀性、吸水率、孔隙率和单位重量，并将其编入数据库以供后续分析。测试程序包括在全尺寸测试中使用具有不同段组成的六种市售锯片。锯片的相关特性是金刚石浓度、硬面基体的维氏硬度、平均金刚石粒度、钴、锡、铜和亚铁含量。13 种不同的碳酸盐岩，包括大理石、石灰岩、来自土耳其不同地点的石灰华样品用于实验计划。通过多元线性和非线性回归分析对实验数据进行分析，以开发使用岩石特性和锯片段参数估计比能量 (SE) 和比磨损 (SW) 率的模型。通过将其预测结果与实际测试结果进行比较，对所提出的模型进行了验证，并显示出良好的一致性。在估算锯片磨损寿命的背景下，还讨论了天然石材切割的最佳总（切割）成本 (OTC) 估算概念。通过多元线性和非线性回归分析对实验数据进行分析，以开发使用岩石特性和锯片段参数估计比能量 (SE) 和比磨损 (SW) 率的模型。通过将其预测结果与实际测试结果进行比较，对所提出的模型进行了验证，并显示出良好的一致性。在估算锯片磨损寿命的背景下，还讨论了天然石材切割的最佳总（切割）成本 (OTC) 估算概念。通过多元线性和非线性回归分析对实验数据进行分析，以开发使用岩石特性和锯片段参数估计比能量 (SE) 和比磨损 (SW) 率的模型。通过将其预测结果与实际测试结果进行比较，对所提出的模型进行了验证，并显示出良好的一致性。在估算锯片磨损寿命的背景下，还讨论了天然石材切割的最佳总（切割）成本 (OTC) 估算概念。
