Machine specification

 

The machine specification contains the following details:

Name

Machine name.

Code

ĮMachine model, code.

 

Controller name

Name of the machine controller.

Description

ĮA more detailed description of the machine.

 

Work area length

The description of the working space boundaries in X direction.

This plays a role in determining whether the workpiece of a given size may be processed in this machine. If the value 0 is indicated, then such a check is not performed.

Work area width

The description of the working space boundaries in Y direction.

This plays a role in determining whether the workpiece of a given size may be processed in this machine. If the value 0 is indicated, then such a check is not performed.

Work area height

The description of the working space boundaries in Z direction.

This plays a role in determining whether the workpiece of a given size may be processed in this machine. If the value 0 is indicated, then such a check is not performed.

Machine type

Describes the machine type. Two options are available:

CNC processing center

Nesting Router


     

 


The selection of this characteristic determines how Woodwork for Inventor CAM will behave during a contour Mill operation. The automatic contour selection mechanism of the milling operation is designed so that during the creation of CAM technological operations required for the CNC processing centre, the system analyzes which external contours of the part need to be selected for the milling operation. The system automatically rejects the external surfaces that are obtained following the cutting of the workpiece which is performed during the operations where the board is cut into rectangular-shaped workpieces. All this is shown on the left hand side of the figure below. In case of a machine for cutting parts from boards, the above rule is ignored and the entire external contour of the part is automatically included in the set of geometric components of the milling operation as shown on the right hand side of the figure below.

Correction on air

Different algorithms are activated for the mechanism used to represent the mill tool trajectory. Some CNC machines or front-end CAM systems interpret the tool Radius correction

commands differently. Some of them interprets that the tool that moves to the first trajectory point at a rapid pace is positioned in the corrected position and this corresponds to the On value. Other systems perform tool correction by moving along the first trajectory segment. This corresponds to the Off value.

 

 

 

Correction on air explanation

 

Clearance height

Specifies a safe height above the part surface that the tool rapids to vertically.

 

Clearance and safe plane exploration

 

 

Safe plane height

Specifies a safe travel height that the tool rapids to horizontally above the part surface.

Post processor

Specifies the Post Processor which processes the created trajectory and outputs it to a file format for a given machine or a front-end CAM system.

All Post Processors are contained in the following Directory:

 

C:\Program Files\Woodwork for Inventor 2015 v6\Postprocessors\

 

Postprocessor output format

Field indicating what file extension the output file will have. This parameter cannot be adjusted and it comes together with the selected Post Processor.

CNC machine screensaver field

Each machine can have a screensaver with an image up to 200kB in size. Users may change this image at their own discretion.

 

 

Spindle list

 

As already mentioned, the spindle list is part of the CNC machine specification which is filled in so that it corresponds to the configuration of the real CNC machine. Click here for information as to what spindle data is stored.
