Stock tab reference

Stock tab settings

The toolpath is calculated based on then size of the stock around the model being machined. An accurate description of the stock will give you the best toolpath results. Stock & fixtures are considered when simulating the toolpath, and by some machining toolpath strategies.

Modes for Rectangular Stock

stock mode - automatic - fixed and relative size box

Fixed size box - Create a rectangular stock boundary that is a specified (fixed) size.

Relative size box - Estimates a rectangular stock boundary around the part. Includes options to offset additional stock around the part and to round up to a specified increment.

Dimensions - Displays the Width (X), Depth (Y), and Height (Z) dimensions of setup stock.

Fixed Size Box Mode

The default Fixed size box mode lets you enter precise XYZ values to specify the width, depth, and height dimensions of your stock. You may position the stock in reference to the left, right, front, back, top, bottom or the Design Origin of the model. Model Design Origin may be different from the Setup WCS Origin.

Tip: Fixed size box mode is useful when working with existing bar stock of a specific width, depth and height.

Ground Stock at Model Origin - When enabled this forces the stock to be in relationship to the origin of the Model. When disabled you will see the options shown below.

Width (X), Depth (Y) and Height (Z) represent the raw stock block size and are always specified with positive values.

stock size

Offset values can be positive or negative and are used to shift the raw stock relative to the selected reference position (Left, Right, Front, Back, Top, Bottom).

stock offset

Model Position options X

Offset from left side (-X) - Set the reference to the furthest X negative position.
Center - Set the reference to the center of the model in X.
Offset from right side (+X) - Set the reference to the furthest X positive position.
Offset from the model origin - Set the reference to the X origin of the Models Design.

Model Position options Y

Offset from back side (+Y) - Set the reference to the furthest Y positive position.
Center - Set the reference to the center of the model in Y.
Offset from front side (-Y) - Set the reference to the furthest Y negative position.
Offset from the model origin - Set the reference to the Y origin of the Models Design.

Model Position options Z

Offset from top (+Z) - Set the reference to the furthest Z positive position.
Center - Set the reference to the center of the model in Z.
Offset from bottom (-Z) - Set the reference to the furthest Z negative position.
Offset from the model origin - Set the reference to the Z origin of the Models Design.

Round Up to Nearest - Rounding up increment for the final stock size.

Ground Stock at Model Origin - Enabled

When enabled, Fixed Size box dialog displays a different set of options. You may define the stock in relationship to the origin of the Model. To see the Model Origin, go to the Browser, expand Models and change the visibility of Origin. Model Design Origin may be different from the Setup WCS Origin.

model origin

Width (X), Depth (Y) and Height (Z) represent the raw stock block size and are always specified with positive values. Same as above.

Offset values can be positive or negative and are used to shift the raw stock relative to the Model Origin.

Round Up to Nearest - Rounding up increment for the final stock size.

Relative Size Box Mode

Selecting the Relative size box mode approximates the required stock size. Includes options to add stock to the top, bottom, and/or sides of the stock.

Modes for Cylindrical Stock

stock mode - cylindrical - fixed and relative size

Fixed size cylinder - Creates a cylindrical stock boundary that is a specified (fixed) size.

Relative size cylinder - Estimates a cylindrical stock boundary around the part. Includes options to offset additional stock around the part and to round up to a specified increment.

Dimensions - Displays the diameter and length of cylindrical setup stock.

Offset from front - Positions the stock such that it is flush with the front face of the model.
Center - Centers the model within the cylindrical stock.
Offset from back - Positions the stock such that it is flush with the back face of the model.

Relative Size Cylinder Mode

Relative size cylinder mode estimates a cylindrical stock boundary around the part. Includes options to offset additional stock around the part and to round up to a specified increment.

Continue Rest Machining - When enabled you may perform Rest Machining operations based on the previous Setup (Turning Operation type only).
Axis - Select the Face, Edge or Arc that represents the axis of the cylindrical stock (Milling Operation Type only).
Radial Stock Offset - Additional amount to offset radially.
