Finish milling with a ball end mill is a key process in manufacturing high-precision and complex workpieces, such as dies and molds. Because of the complexity of the milling process, it is difficult to evaluate the microcharacteristics of machined surfaces real time, which necessitates the simulation of the process.

In the past the conventional method of driving large ball mills included some form of speed reducing gear between the higher speed driving motor and the lower speed ball mill. Process developments in the mining and cement industries have increasingly tended toward the use of ever larger ball mills for grinding their products. As the horsepower drive ratings required have increased to several

Also, the CNTs were pre-coated to improve the agglomeration of the CNTs with copper powder. The main aim of this work is the fabrication of Cu-CNT nanocomposite powder using the MA by ball milling. The as-received dendritic copper powders change their shape sequentially to flaky, disk-typed particles and finally, to globular type particles.

The following post focuses mostly on 3D toolpaths so we’ll be assuming the use of a ball mill. Once you understand the basic concepts it’s easy to apply them to flat end mills and bull mills. We’ll try to build to some rules of thumb rather than derive equations that most users won’t be interested in.

The overall reach of an end mill, or length below shank (LBS), is a dimension that describes the necked length of reached tools. It is measured from the start of the necked portion to the bottom of the cutting end of the tool. The neck relief allows space for chip evacuation and prevents the shank from rubbing in deep- pocket milling applications.

A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls; mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 – 50 % of the mill volume and its size depends on the feed and mill size.
