The Development and Research about the Teaching-cases
for Custom Macro C Machining
Summary
In this paper, the development and research of teaching cases has been
implemented which concerned with custom macro programming C lathe, CNC milling
machine and machining center, based on the custom macro function provided by
C system and to meet the needs of the course "CNC programming" theory
teaching and practice teaching, vocational skills training and training before
C petition, as well as the quality employment of C
technology application specialty and other related ones’ students in vocational
schools. It has been done at the beginning to research several different macro
programming ways of arc approximation for non-circular curve, to find solutions
about processing pause and excessive cutting caused by plex calculations
leading to time-consuming, and the macro programming of approximation error’s
calculation and control, furthermore, to realize equal-error linear/arc
approximation for non-circular curve, as well as to explore programming skills,
etc. Then, in the light of the research results, the teaching cases has been
developed which can meet the vocational schools’ needs of theory/practice teaching
for C technology application specialty in different levels. This paper
concentrate on the realit
