Rapid thermal processing (RTP) refers to a semiconductor manufacturing process which heats silicon wafers to high temperatures (over 1,000 °C) on a timescale of several seconds or less. During cooling, however, wafer temperatures must be brought down slowly to prevent dislocations and wafer breakage due to thermal shock.

manufacturing capabilities of the equipment available. Because TD is a manufacturing process, it is very important at the design stage for the engineer to take into consideration the capabilities of the process. If at the start of the design of a new part a Thermal Deburring specialist is
Abstract. This chapter describes thermal-type HMPs in which EDM as the primary process of material removal is combined with either a conventional machining/finishing process or with an electrolytic dissolution-based process for improved machining/finishing characteristics …
In contrast, ultrasonic machining (UM or USM) is a non-thermal, non-chemical and non-electrical machining process that leaves the chemical composition, material microstructure and physical properties of the workpiece unchanged.
A Model Camshaft Grinding Process. ... Thermal modeling allows the manufacturing engineer to model a new camshaft design and report back to the designer and metallurgist what the model predicts will happen to the camshaft during grinding, and whether this is acceptable based on material and design.
