This cycle is set up much the same way as a normal straight cut, except use the tool number for the four-axis saw head. Router-CIM will interpret the axis geometry and all moves required to complete the cycle. The Control Panel settings for this cycle are the same as for a 2D cycle.
• The 4 Axis Safe field has no function in this cycle.
• The Tool Length field is used to determine the distance from the center of the saw to the center of the blade.
• Cutter Compensation is available in this cycle.
4 Axis Saw tool paths.
4th Axis Saw parameters.
The following parameters effect the toolpath creation:
The saw offset is the amount the toolpath is offset from the original geometry or Geoshape.
Normally this is set by Router-CIM depending on a number of features such as the Cutter Compensation setting and the cut cycle itself. For instance if Cutter Comp is set to Yes, then the toolpath will lie directly on top of the Geoshaped geometry with no offset.
For a saw, you might want the tool path set on top of your geometry with no offset (use 0) or offset by some amount relative to your saw spindle or aggregate.
You may substitute the parameters here for numeric values to suit you particular cutting needs.
See Offset Dim for information that is relevant to Saw Offset as well.
Cut Side is the side of the Geoshape that the toolpath will be created on. For instance Plunge-Outside (Plunge-O) will have the toolpath on the outside of the shape. Valid entries for this field are Outside, Inside, RH (Right Hand) and LH (Left Hand).
See the Cut Side section for more information.
The direction of the cut can only be clockwise (CW) or counter-clockwise (CCW). This even applies to open shapes where this direction really has no meaningful relationship to the geometry selected. Any closed shapes should have the direction set accordingly and any open shapes should be set to CCW as all shapes in AutoCAD and Router-CIM are CCW by default.
See the Cut Direction section for more information.
This field defines the lead-In block name. There are several available, but only some cycles will respond to the change of the Lead-In edits. By default this cycle will usually not have the lead-in or lead-out changed as the defaults will accommodate multiple depths per pass and cutting on any plane.
See the Lead-In section for more information.
This field defines the lead-Out block name. There are several available, but only some cycles will respond to the change of the Lead-Out edits. By default this cycle will usually not have the lead-in or lead-out changed as the defaults will accommodate multiple depths per pass and cutting on any plane.
See the Lead-Out section for more information.
Use Lead Size to change the length of the leads. This field will affect both lead-in and lead-out if you put just one number in this field. You can put two numbers in this field, separated by a space, and the first number will affect the lead-in and the second will affect the lead out.
See the Lead-Size section for more information.
This sets lead-in and lead-out feed rates. The default is 0.5, Router-CIM's standard 50% feedrate for lead-in and lead-out.
Setting a number between 0 and 1.0 will give you a percentage of the max feedrate (for instance 0.4 would be 40%).
Setting the number to a value greater than 1.0 will give you an exact feedrate. For instance 250. would generate F250. in the code.
See the Lead Feed section for more information.
**Changing values in the cycle parameters may yield unexpected results with some settings or on some geometry. Examine the toolpath and NC Code carefully before running your machine tool if you change these default settings.
