Fixing linear positioning errors: General Industry Coverage
In a typical machine-tool-axis positioning system, the workpiece is mounted on a table that slides along flat, straight guide ways. The table may be supported on the guide ways by rolling elements or by a thin film of oil or grease. A screw controls the table position along the guide way.

A clear view on vision panels
The cutting zone in a machine tool is dangerous. Hot chips and large quantities of coolant are often safety threats, but a tool rotating at a high speed is an even greater one.

Measuring with capacitance sensors: General Industry Coverage
Capacitance sensors are noncontact sensors used in machine tools to measure the distance between a noncontact probe and a target sensor. Because the probe does not physically touch the target, capacitance sensors are beneficial in instances where the target surface is moving, such as a rotating spindle, or delicate, such as a silicon wafer.

Pros and cons of different guide ways
Scraping is one of the oldest and most historically significant metal-removal processes, notes Dr. Scott Smith in his Machine Technology column of the September 2014 issue of Cutting Tool Engineering magazine.
Milling with constant force

Milling with constant force
There are many reasons for cutting force to vary, even during stable milling. These include tool teeth entering and exiting the cut, instantaneous changes in chip thickness, and tooth orientation changing as the tool rotates. However, it is possible to arrange the cutting conditions in a simple way and keep the cutting force constant.
