Roughing

 

Using roughing passes, you can remove large volumes of material from a part with a large tool prior to making a finish pass (or passes) with a smaller tool.  This helps lower the overall cycle time and save on tool wear.  There are several methods of rough cutting in Router-CIM, and each will be described in as much detail as possible.  There are example cuts shown for each method that employ settings that are intended to show the method and settings of the cycle, though are not necessarily the most efficient settings for that particular tool or cycle.

 

 

Vertical Cutting + Mode 1

Offsets each roughing pass by "Rough Z Cut Increment" + "Stock Allowance", moving in rapid when machine motions exceed "Working Area Z Maximum".

 

The available cycles for this method are Nurbs_XZ and Nurbs_YZ.

 

Vertical Cutting + Mode 2

Offsets each roughing pass by "Rough Z Cut Increment" + "Stock Allowance", and proportionally distributes Z depth throughout the roughing activity without allowing tool to leave material.

 

The available cycles for this method are Nurbs_XZ and Nurbs_YZ.

 

Vertical Cutting + Mode 3

Shifts roughing motions in "Z" based on "Rough Z Cut Increment" while compensating for "Stock Allowance", moving in rapid when machine motions exceed "Working Area Z Maximum".

 

The available cycles for this method are Nurbs_XZ and Nurbs_YZ.

 

Horizontal Cutting + Mode 1

Plunges straight down to each Z level, compensates for "Stock Allowance", roughs without following collective surface contours before proceeding to next lower Z level. Plunge Points can be used in conjunction with this method of roughing.

 

The available cycle for this methods is Nurbs_CCW_XY.

 

Horizontal Cutting + Mode 2

Ramps down to each Z level, compensates for "Stock Allowance", roughs and makes a contour following pass while ramping down to next Z level.

 

The available cycle for this methods is Nurbs_CCW_XY.

 

Horizontal Cutting + Mode 3

Plunges straight down to each Z level, compensates for "Stock Allowance", roughs and makes a contour following pass before plunging straight down to next Z level. Plunge Points can be used in conjunction with this method of roughing.

 

The available cycle for this methods is Nurbs_CCW_XY.
