“…The generation of an accurate motion along the offset of the trochoid curves is treated as a locus tracing problem. The concept is generally applicable in motion generation and has already been tested successfully in similar problems of CNC machining [9][10][11][12]. In this paper, its application is illustrated in the context of motion generation along the offset of a trochoid.…”

This paper presents a manufacturing method for parts with trochoidal profile on CNC milling machines. The method is based on a new real-time interpolation algorithm capable to drive the cutter along the offset of trochoid curves with precision equal to the resolution of the machine. The structure of the presented algorithm may be adapted accordingly so as to be used either for parts with an epitrochoidal or a hypotrochoidal profile. Both types of curves, known as trochoid curves, have important industrial applications such as gears with trochoidal tooth-profile, cams, trochoidal-shaped housings for rotary internal combustion engines and rotary piston pumps etc. The effectiveness and accuracy of the proposed method is verified by simulation tests of the generated tool path for the machining of two representative mechanical parts, an inner rotor of a hypogerotor pump and an epitrochoidal-shaped housing.

“…In this section, the generation of an accurate motion along the offset of an ellipse is treated as a locus tracing problem [10]. The specific concept has been already applied successfully in motion generation for a series of CNC interpolation algorithms [11][12][13]. The main concept of this approach may be summarized as follows: Using analytic concepts and the locus defining property, two distinct sophisticated constructive operations are formulated.…”

This paper proposes a set of four elliptical features that can enhance the programming capabilities of a modern CNC system. Namely, a real-time interpolation algorithm for motion generation along an ellipse and its offset, machining of an elliptical pocket, and drilling a series of equidistant holes along an elliptical path. The paper analytically describes the implementation of the new functions while the G-codes, along with their complementary requisite data needed to be introduced in the CNC part program, are exemplified with simulation and actual machining tests for each feature.
