CAM

A CAM (Camshaft) is a connection mechanism between a master Drive and a slave Drive, often used in packaging machinery and other automation systems. CAMs allow the slave drive to move in relation to the master drive according to a predefined CAM profile. This is particularly useful for controlling complex motion profiles in automated systems.

CAM profiles can be defined and imported into Unity through various file types. The CAM component supports both Excel and CSV formats for defining these profiles.
Excel: .xlsx files.
CSV: .csv files.
MasterDrive The master drive to which the slave drive is attached. The slave drive's position will be determined by the master drive's position according to the CAM profile.
MasterDriveAxisScale A scale factor applied to the master drive position to get the value used in the CAM curve.
MasterDriveAxisOffset An offset added to the master drive position to determine the value used in the CAM curve.
CAMAxisScale The scale factor for the CAM axis. It scales the values of the CAM curve.
CAMAxisOffset An offset added to the values of the CAM curve to determine the position applied to the CAM (slave) axis.
ExcelSheet Name of the Excel sheet used when importing CAM data from an Excel file.
ExcelFile Path to the Excel file used for importing CAM data.
CamDefintion A text asset containing the CAM definition. This asset is a table with optional headers and columns describing the master axis position and the slave axis position.
UseColumnNames Indicates whether column names are used to define the data to import.
MasterColumn The name of the column in the text asset that contains the master axis position.
SlaveColumn The name of the column in the text asset that contains the slave axis position.
UseColumnNumbers Indicates whether column numbers are used to define the data to import.
MasterColumnNum The column number (starting with 1) that contains the master axis position in the text asset.
SlaveColumnNum The column number (starting with 1) that contains the slave axis position in the text asset.
CamDefinitionWithHeader Indicates whether the first line of the text asset is a header.
ImportOnStart Indicates whether the CAM data should be imported automatically when the simulation starts.
IsContinous Indicates whether the CAM should continue as an offset based on the last CAM position, useful for continuous movements like transport chains.
Usage Instructions
Select CAM File: Choose the CAM profile file using the ExcelFile or CamDefintion property, depending on whether you are using Excel or CSV.
Set Scaling and Offsets: Adjust the MasterDriveAxisScale, MasterDriveAxisOffset, CAMAxisScale, and CAMAxisOffset properties to fit your application's requirements.
Import CAM Profile: Use the ImportOnStart property to automatically import the CAM profile when the simulation starts.
Configure Continuous Mode: Enable IsContinous if the CAM profile should operate continuously. Adjust ContinousOffset as needed.
