This tool will hold right-handed turning tools and will be mounted on the face of the turret.
For a mill/turn machine, the holder is held by tool blocks. The tool blocks are most likely supplied by your machine tool vendor. As such, they are stored in the machine design file. Each tool block must be represented by a separate solid model. Tool blocks should not be associated with the machine through a parent/child relationship. The solids only have to be identified as a tool block and the appropriate block will be displayed along with the selected tools during machine simulation. The tool blocks can be modeled in any location.
You may design your tool block solids out in space, or "in place" such that they "plug into" tool slot #1. That is, the Tool block for Turret dialog will require two UCS's - the purpose of the left-hand's UCS is to transform the tool block into the turret and the other is used to "mate" the tool and the tool block. If you design your tool block out in space, the left UCS will tell Featurecam how to transform the tool block into the turret. That is, this UCS will "mate" with the tool location on the turret (positionally as well as rotationally). Featurecam will transform the tool block such that the position, +X, and +Z are all matched to the turret "tool location". I.e., the +X of this UCS matches with the +X of the tool location on the turret, origin is origin, and +Z is +Z. If you design your tool block in tool slot #1 (i.e., there is no need to transform the tool block into the turret), use the same UCS as the tool location slot #1 on the turret. The right UCS is used to "position" the tool relative to the tool block. In some sense, you can think of this as "adding a tool location" to a tool block solid. i.e., the tool holder is aligned with the minus Z direction of the "mating tool" UCS. There are three basic types of tool blocks - those that hold OD turning tools, those that hold X-rotary tools, and those that hold ID turning tools (boring bars), drills, and other Z-axis aligned milling tools. Additionally, you may wish to differentiate between a OD turning toolblock for left-handed tool versus a right-handed tool. There is also an option for X-rotary tools - you can mount them on the OD of the turret or on the face of the turret. If, when adding a tool location on the turret, you specified the tool position was on the face of the turret, you should use the face-mounted option here in this dialog as well. (The converse is also true, if the OD mounted tool was used as a tool location, please use the OD mounted X-tool block). Currently, if you use any left-handed turning tools, you must add a left-handed tool block. (Eventually, FeatureCAM could use a mirror of the right-handed tool block). If you cannot mount a tool to the OD of your turret, you do not need to define an OD mounted tool block. You must, however, have at least one solid tool block defined for every tool-type that you intend to simulate. If you do not define an OD-turning toolblock, FeatureCAM will attempt to use an OD mounted X-tool block for any OD turning tools. In this manner, you can generally define a machine with only two toolblocks, one for OD turning and X-tools, and another for ID boring bars and other Z-tools. Currently, you cannot use same solid for different types of toolblocks.
This may be somewhat confusing when adding a tool location to a toolblock, but think of it in terms of a milling machine. The tool is going to be aligned such that the tool holder is parallel to the -Z axis of the tool location's UCS. This is true whether you are considering milling live-tool holders, OD turning holders, or ID turning boring bars, or Z-aligned drills. The positive Z direction will point into the tool block.
You need only to define tool blocks for the main turret. Tool blocks with appropriate transformations will be used for the sub-turret automatically.
Solids are identified as tool blocks by using the Tool block for turret command from the Machine design menu.
To complete this dialog box:
Select the solid.
Select the first UCS. This UCS is the mounting location to turret shown in the figure below. This location will be mated with the tool location specified for the turret. The dialog labels this location as This UCS will match up with the tool location on the turret.
The second required UCS is labelled The
tool is located by this UCS. This
is the location where the actual tool will be placed on the tool block.
In the
example below, this UCS is labelled Tool Location.

Identify the type of block. This information will be used to select the appropriate tool block for a particular tool. Currently, you cannot use same solid for different types of toolblocks.
