The author has analyzed
features of forming non-circular profiles described by
cycloidal
curves and their equidistant curves
.
The research for the processing schemes of multifac-
eted details by an eccentric circular cutter has been carried out
.
A method of producing a
multi-faceted profile by running of the forming circles related to the work piece and the
cutter has been applied.
Study of the scheme parameters and the relative trajectories of
the tool were performed by using unified mathematical form of expressing cycloidal tra-
jectories in the form of parametric equations
.
The influence on the shape of the faces of
the machine parameters, tools and relationship of angular velocities of absolute move-
ment
is shown. To illustrate this,
the parameters of processing schemes by an eccentric
cutter ensuring the straightness of the product faces
were determined.
When studying
product forms, the cutter center path
was considered
. The
effect of the change of the
shear layer cross-section and of kinematic cutting corners on the patterns of change in
the force parameters of processing
was educed.
Schemes of cutting allowance were
formed by using modern information technologies
. The author provides
features of pass-
ing certain relative trajectories of the cutter peaks via allowance.
Recommendations on
the use of research results are offered
.
Keywords:
kinematic analysis, forming, non-circular profile, cycloidal processing
scheme, cutting corners, scheme of cutting allowance, the kinematic error.
