Parameters

Micro Milling	When this checkbox is marked ,this defines the stock procedure as Micro Milling—If the procedure is located in the Micro Milling toolpath (TP) folder, the checkbox is ON by default; otherwise it is OFF. Changing the checkbox in an existing stock from Normal to Micro Milling will invalidate all relevant stock calculations of subsequent procedures (after a warning). Changing the checkbox in an existing stock from Micro Milling to Normal does not result in any other changes. When calculating stock, the tolerance is considered as Micro Milling in either of the following circumstances; If the relevant stock is defined as Micro Milling. If the procedure itself is Micro Milling (that is, it is located in the Micro Milling TP folder).
Transparency	Control the hide/show state, transparency, and color of the stock. See the Stock Display Options for the relevant detailed parameter explanations.

Ref. Stock Size	The reference stock size based on the entities you have selected. This area shows the size of the stock. The values are for reference only and cannot be changed in this dialog. The Z distance is the difference between the Max. Z and Min. Z values (in the Selected Geometry section of this dialog).
Selected Geometry	Define the minimum and maximum Z of the stock.
Max. Z	The maximum Z of the stock. This is a system defined parameter and is based on the highest point of the part.
Min. Z	The minimum Z of the stock. By default, this is based on the lowest point of the part. This minimum Z can be shortened or extended. If this distance is changed, the Z value of the Ref. Stock Size ( in this dialog ) is automatically updated. Set the Min. Z value using one of the following methods: entering the Z level in the dialog, using the yellow arrow in the dialog ( ), pick the bottom point of the stock. Notes: If the Min. Z is shortened or extended, only the following functions recognize the change: - Rough - Finish - Cleanup - Pencil The Simulator and Verifier recognize an extended Min. Z. However, the default Min. Z or a shortened Min. Z is extended to the default Min. Z plus an additional distance. This additional distance is automatically calculated as: ZTop - ZBottom ---------------------- 10
Calculate Min. Z	If the Minimum Z has been changed, this option recalculates the default Minimum Z.
Surface Offset	Enter the surface offset if required.
Number of Picked Surfaces	This section displays the number of surfaces picked manually, picked by criteria and also the total number of surfaces picked. By default, all the surfaces in the part are initially selected to form the stock.
