Ball-End Mill with a Loxodromic Cutting Edge

© 2020, Allerton Press, Inc. Abstract: Attention focuses on the design of a ball-end mill whose spherical section has a loxodromic cutting edge. The grinding width and depth required to obtain the rake and rear surfaces and the tooth back are noted

Producing the Front Surface in a Ball-End Mill

© 2020, Allerton Press, Inc. Abstract: Attention focuses on the production of the spherical front surface of a ball-end mill, close to the transition from the cylindrical section. Analysis of the possible interference of the grinding wheel and the mill permits recommendations for decreasing the errors. The shaping errors due to plane approximation of the curvilinear front surface are discussed

Dialog-Based Calculation of Dimensional Relations between Machine Parts
