Use the Machining CostingManager on the left side of the SolidWorks software window to see how the Costing tool categorizes each operation required for manufacturing the part.
To display the Machining CostingManager, in a machined part, click Machined Costing 
(Tools toolbar) or .

Setup
The Setup 
folder contains the costs associated with manufacturing setups such as setting up machines to run a batch (lot) of parts. Each operation to manufacture the part requires a setup cost. The setup costs depend on the time required to set the part on the machines. The setup cost includes the machine cost per hour because the machine cannot be used during setup, and labor cost for the effort to set the part. If the setup cost is in the machining template, it is recognized by the Costing tool.
The Setup folder can have setup costs defined in the template for library features or custom features. The folder also groups all the cutting, milling, and drilling setup costs into appropriate setup operations. For the cutting, milling, and drilling setup costs, a generic 5% of the total operation cost is assumed, which is the amount of time to remove the material for this feature multiplied by the labor and machine cost.
For example, if there is a pocket on the top face of the part to be milled, the pocket is listed in the Mill Operations folder and its setup is listed in a Setup Operation 
folder in the Setup folder. All features that share the same operation direction are placed in the same Setup Operation folder. For instance, a pocket and hole on the top face are in one Setup Operation folder, while a facing operation and a hole on the right face are grouped in another Setup Operation folder.
Expand the Setup folder and hover over a setup cost 
to see how the cost is calculated.
The setup cost is per part.
You can drag and drop individual setup costs to different setup operations in the Setup folder, or you can place them in new setup operations.
Cut Path
Cut path operations are only available when Stock Body is set to Plate in the Machining Costing Task Pane.
Cut paths are the tool paths that 2D machining operations, such as laser, waterjet, or plasma cutting will follow. In a part that starts as plate stock, any through holes, through cuts, or outside boundary geometry that needs cutting is cut using 2D machining operations by default, creating cut paths for these features.
The
Cut Path folder contains the:
- number of cuts required for the part
- cutting method to be used
- cost of each cut
The cost of each cut is calculated by:
Cost = Cut Length * Cost Per Unit Length in the machining template
Expand the Cut Path folder and hover over a cut path 
to see how the cost is calculated. Select a cut path to highlight the geometry in the model.
Mill Operations
The Mill Operations folder contains operations such as pocket, face, and chamfer milling.
Milling operations are calculated using a material removal rate (MRR). Expand the Mill Operations folder and hover over a mill operation to see how the cost is calculated. Select a mill operation to highlight the geometry in the model.
Hole Operations
The Hole Operations folder contains drilling and tapping operations needed to create holes. Appropriate drill and tap sizes are selected from the machining template to best fit the holes in the part. If the proper drill and tap sizes are not in the template, a warning icon 
appears. You can correct the warning by editing the machining template and adding the appropriate drill and tap sizes.
Hole operations are calculated using a material removal rate (MRR) for drilling and tapping. Expand the Hole Operations folder and hover over a hole operation to see how the cost is calculated. Select a hole operation to highlight the geometry in the model.
Custom Operations
The Custom Operations folder contains any operations that are not automatically recognized by the Costing tool. A custom operation cost can be calculated as a cost associated with the entire part, the part weight, specific part faces, part edges, a single stroke operation, or time.
For example, if the part is to be painted, you can assign a cost to paint the entire part or specific faces of a part. If you are painting specific faces, include a cost per area such as dollars per square inch to paint the part.
You can set custom operations in the machining template and apply the operations automatically or manually.
You can also create custom operations without editing the template by clicking Create Custom Operation in the CostingManager.
Each item in the folder has the operation name you selected and the selection type.
Hover over a custom operation to see the equation used to calculate the cost.
Library Features
The Library Features folder contains all library features in the part. The cost of each item is calculated as the cost per feature as defined in the machining template.
Hover over a library feature 
to see the equation used to calculate the cost.
No Cost Assigned
The
No Cost Assigned folder contains features that:
- are not recognized by the Costing tool
- are not defined in the machining template
- have a zero cost
If you set a feature cost to zero, the feature moves to this folder. If you assign a cost to a feature in the No Cost Assigned folder, the feature moves to the appropriate folder and appears in italics with an asterisk to indicate an override. If a feature that you assign a cost to is not a cut path, mill operation, hole operation, or library feature, then that feature is assigned to the Custom Operations folder.
