
12.6.2 read CAM online file
This command being part of menu item 'CAM' by default is used to read in data
describing a CAM from an external file of proprietary type ".cam", which has been
created before by use of the command write CAM online file.
12.6.3 read CAM data from ASCII table
This command being part of menu item 'CAM' by default is used to read in data
describing a CAM from an ASCII file (".txt"). Reading the CAM data into a project you
will be asked on the number of points that shall be taken into account for creating the
CAM within the programming environment. By default the number of data points
contained in the file is proposed, but restricting the amount of CAM data to a smaller
set of equidistantly dispersed points may be reasonable: as the CAM will be
interpolated by polynomials of degree 5, a high number of interpolation points can
result in oscillations.
12.6.4 write CAM online file
This command being part of menu item 'CAM' by default is used to write the CAM data
to an external file of proprietary type ".cam". The CAM data saved includes the
description of the CAM as well as position and type of the tappets and can be read into
another project by use of the command read CAM online file.
12.6.5 write CAM data into ASCII table
This command being part of menu item 'CAM' by default is used to write the data to
an external file of ASCII type ".txt".
Saving the CAM data you will be asked on the number of points, that is the amount of
data describing the CAM. These points will be dispersed equidistantly over the X range
of the cam. The data saved includes the x- and y-position of these points. Be aware
that no information on tappets will not be saved.
The CAM data saved can be read in to a project by use of the command read CAM data
from ASCII table.
