Machinability of Plastics

Machinability of Experimental Ti-Cu Alloys

This study is an investigation of the machinability of experimental Ti-Cu alloys (2, 5, and 10mass% Cu) as new dental titanium alloy candidates for CAD/CAM use. The alloys were slotted with a vertical milling machine and carbide square end mills under two cutting conditions. Their machinability was evaluated through cutting force using a three-component force transducer fixed on the table of th...

Global Machinability of Al-Mg-Si Extrusions

Machinability of experimental Ti-Ag alloys.

This study investigated the machinability of experimental Ti-Ag alloys (5, 10, 20, and 30 mass% Ag) as a new dental titanium alloy candidate for CAD/CAM use. The alloys were slotted with a vertical milling machine and carbide square end mills under two cutting conditions. Machinability was evaluated through cutting force using a three-component force transducer fixed on the table of the milling...

Prediction of steel machinability by genetic programming

Purpose: This paper describes intelligent system to predict steel machinability. Design/methodology/approach: The prediction of machinability of steel, depending on input parameters (percentage of calcium, percentage of oxygen, percentage of sulphur), was performed by means of genetic programming and data on the batches of steel already made. Findings: The mathematical model to predict machinab...

Assessment of Machinability of Metal Cutting

The assessments of machinability of metal cutting are called "indices" and are derived by comparative research. These indices are the relations of two identical parameters, such as is the allowable cutting speed. The assessments were obtained at a constant tool life of 60 min, at the appropriate tool life minimum costs and the efficient reporting of specific restrictions for finishing and rough...
