Stock Analysis

Introduction

This topic will explain the Stock Analysis tab, and the options found in it. This topic will also provide links to related topics.

The Stock Analysis Tab

The stock analysis applies color schemes to the stock material which allows you to analyze the stock after operations are performed in simulation.

Stock Analysis Buttons

The following four buttons display at the top of the Stock Analysis tab in the simulation window. Not all buttons are available for all Stock Analysis options, and some of them change their use depending on which Stock Analysis option you select.

Refresh Cutsim - updates the stock model in the simulation window to the currently selected Stock Analysis option and colors. You should click Refresh anytime that you change a Stock Analysis parameter such as the colors used. When the analysis is current, this button changes to .

Auto Adjust or Min/Max Detection - updates the Stock Analysis in one of two ways. For most Stock Analysis options, this resets the analysis colors to their default values. When using the Deviation option, this button analyzes the minimum and maximum amount of deviation in the cut model versus the workpiece, and then updates the Start and End values in the Stock Analysis tab.

Match Tool Flute Color - displays the tool flute in the same color as the current tool or operation color that is defined in the Stock Analysis tab. So as the simulation runs, the tool flute color changes to match each operation or tool number color. This option is available when you are using either the Tool Number or Operation Number analysis options.

Stock Analysis Options

The Stock Analysis can be turned off by selecting None. When you turn off the Stock Analysis, the stock material displays only in the defined stock color. All other Stock Analysis options are described next.

Tool Number or Operation Number

The toolpath is colored after the different tools or operations being used.

Main benefit

  • Identify the amount of different tools or operations being used.

  • Identify the area a certain tool is performing a machining (roughing, finishing etc.).

Example

The following picture shows a machining of a bottle. The material is colorized after the different tools being used. As you can see there are four different tools (or operations) used for the machining.

Deviation

The deviation is a material offset compared to the target geometry. The color of the material changes the more or less material exists on top of the target geometry.

Main benefit

  • Identify the amount of the material left on the target geometry.

  • Identify the gouges, when too much material was removed and the target geometry is being damaged.

  • Identify area where a rest machining is necessary.

Example

The following picture shows a machining of a bottle. The colorization is from green (min. material left) to blue (max. material left). You see two significant results:

  • Due to the step over of the machining big cusps are left on the machining surface (left side).

  • The tool used was too big to get into the area between the bottle neck and bottle head. A rest machining is necessary.

Height Change

The height change indicates whether the tool is ascending or descending.

Main benefit

  • Identify if there are plunge motions in the material. In this case the tool must be able to perform plunging.

  • Identify the cutting method, Zig Zag or OneWay.

Example

The following picture shows a machining of a male formed part. The colorization is red (for plunging) and blue (for retracting). The machining is OneWay, starting from one side going to the other side.

Orientation Change

The material is colorized after the orientation change of the machines rotation axis.

Main benefit

  • Identify the rotation speed range being used.

  • Identify under which rotation speed a certain area is machined.

  • The rotation speed gives feed back where machine speed limits are reached and where you can expect stability issues of the process which influences the final surface quality.

Example

The following picture shows a machining of a turbine blade. The colorization is from blue (low rotation speed) to orange (high rotation speed). You see that especially in the small corner radius the orientation speed is high. The quality in this area could suffer.

Toolpath Length

The toolpath length indicates the length of the toolpath segments.

Main benefit

  • Identify if the toolpath points are equally distributed on the workpiece. A constant distribution generally is better for the machining process and stability.

Example

The following picture shows a machining of a bottle. You see that the toolpath length varies in certain areas. The toolpath points are not equally distributed.

Mark Parts

The part is colorized into chips which have been separated from the main part.

Main benefit

  • Identify the chips which result after the machining.

Example

The following picture shows the part after machining. It is divided into two parts now.

Single Marking

The Single Marking analysis option displays all cut material using the same color. You can double-click the small color box, next to Color for Cut Material, to select the desired color. To update the model after selecting this option, click Refresh. This option is useful when you want to view all cut material in a single color. This option can also be used when taking screen shots of the stock material.

Example

The following image shows a stock model with Operation Number analysis.

After selecting the Single Marking analysis option, selecting a color, and then clicking Refresh, the stock model appears as shown next.

Gouge Excess

The gouge and excess stock analysis option displays three colors to represent the gouging, within threshold/tolerance, and excess material areas of the cut stock in the simulation window. If you make any adjustments to the colors or settings for the gouge and excess option, click the refresh button to update the cut stock in the simulation window.
