In Autodesk Inventor HSM you can control the machining area by depth for most machining strategies on the Heights tab. The machining area is defined by the Top Height and Bottom Height. On the Heights tab, you can also control the retracts by setting the Clearance Height, Retract Height, and Feed Height. Each height is defined by an offset amount and a mode that tells from which other height the offset applies. The absolute heights are always in relation to the operation origin which defaults to the WCS defined in the setup the stock.

Below we will explain the different options on the heights tab.

Clearance Height

The Clearance height is the first height the tool rapids to on its way to the start of the tool path.

Clearance height offset

The Clearance height offset is applied and is relative to the Clearance height selection in the drop-down list below.

Retract Height

Retract height sets the height that the tool moves up to before the next cutting pass. Retract height should be set above the Feed height and Top. Retract height is used together with the subsequent offset to establish the height.

Retract height offset is applied and is relative to the Retract height selection in the drop-down list below.

Feed Height

Feed height sets the height that the tool rapids to before changing to the feed/plunge rate to enter the part. Feed height should be set above the Top. A drilling operation uses this height as the initial feed height and the retract peck height. Feed height is used together with the subsequent offset to establish the height.

Feed height offset is applied and is relative to the Feed height selection in the drop-down list below.

Top Height

Top height sets the height that describes the top of the cut. Top height should be set above the Bottom. Top height is used together with the subsequent offset to establish the height.

Top offset

Top offset is applied and is relative to the Top height selection in the drop-down list below.

Bottom Height

Bottom height determines the final machining height/depth and the lowest depth that the tool descends into the stock. Bottom height needs to be set below the Top. Bottom height is used together with the subsequent offset to establish the height.

Bottom offset

Bottom offset is applied and is relative to the Bottom height selection in the above drop-down list.
