Tool

The Tool object represents a tool within the program. All the methods for creating toolpaths take one or more Tool objects as arguments. Any of the supported tool types can be accessed from the ToolDatabase as shown in the section describing the ToolDatabase:SelectTool() method. In addition, the most common tool types (BallNose, EndMill, VBit and Drill) can be created programmatically from Lua.

Constructor

Tool( string name, ToolType tool_type)

Create a new tool. Only a limited number of tool types are supported for creation from script. To access the full range of tools use the ToolDatabase:SelectTool() method to allow users to select tools from the tool database. Name (string) Name for the too to be created tool_type (integer)Type of tool to create.

Valid values are:

Tool.BALL_NOSE

Tool.END_MILL

Tool.VBit_angle

Tool.THROUGH_DRILL

NOTE: If you change ANY parameters or properties on a tool retrieved from an EXISTING toolpath, you MUST call UpdateParameters() after you have finished editing tool properties to flush the changes through to the toolpath.

:UpdateParameters()

If editing a tool on an existing toolpath update feed rates and other parameters set on the tool to new values.

NOTE: You MUST call this method if you have edited any parameters on an existing tool, otherwise your changes will be ignored!

For Example:

 -- Create tool we will use to machine vectors
   local tool = Tool(
                     "Lua End Mill",
                      Tool.END_MILL      -- BALL_NOSE, END_MILL, VBIT
                    )
   tool.InMM = tool_in_mm
   tool.ToolDia = tool_dia
   tool.Stepdown = tool_stepdown
   tool.Stepover = tool_dia * 0.25
   tool.RateUnits = Tool.MM_SEC -- MM_SEC, MM_MIN, METRES_MIN,
                                -- INCHES_SEC, INCHES_MIN, FEET_MIN
   tool.FeedRate = 30
   tool.PlungeRate = 10
   tool.SpindleSpeed = 20000
   tool.ToolNumber = 1
   tool.VBitAngle = 90.0                    -- used for vbit only
