Glossary Terms
bur
Tool-condition problem characterized by the adhesion of small particles of workpiece material to the cutting edge during chip removal.
burning
Rotary tool that removes hard or soft materials similar to a rotary file. A bur’s teeth, or flutes, have a negative rake.
burnishing
Finishing method by means of compressing or cold-working the workpiece surface with carbide rollers called burnishing rolls or burnishers.
burr
Stringy portions of material formed on workpiece edges during machining. Often sharp. Can be removed with hand files, abrasive wheels or be…
bushing
Cylindrical sleeve, typically made from high-grade tool steel, inserted into a jig fixture to guide cutting tools. There are three main typ…
button cutter
Round insert that is able to spread the stresses generated by the cutting forces over a larger area than other insert shapes. However, a ro…
computer-aided design (CAD)
Product-design functions performed with the help of computers and special software.
feature-based CAD/CAM
Construction methodology. It means the model is constructed using 3-D objects (features), as opposed to individual lines, arcs, splines and…
parametric-based CAD/CAM
Model features can be driven by rules or parameters set up by the user. They can be dimensions, geometric constraints (tangent, concentric,…
computer-aided engineering (CAE)
Engineering functions performed with the help of computers and special software. Includes functions such as determining a material’s abilit…
calibration
Checking measuring instruments and devices against a master set to ensure that, over time, they have remained dimensionally stable and nomi…
