DIN4003 coordinate system naming scheme

The DIN4003 standard defines how 3D graphic models for different tool component classes must be designed. This standard also defines the coordinate systems in the tool components using the following naming scheme:

MCS

Machine-side coordinate system

CSW

Coordinate system workpiece-side

A tool component always has one MCS and any number of CSWs, depending on its design. If it has a single CSW, the coordinate system is called CSW. If it has multiple CSWs and dedicated steps (see example), the coordinate systems are additionally numbered in ascending order, using a system that is dependent on the shape of the component. The examples provide an introduction to the naming convention.

Tool component	MCS	CSW
Insert: DIN4003_76_01 [TC_INSERT_10_00_100]	Pointing toward the holder	None

Tool component	MCS	CSW
Holder: DIN4003_90_02 [TC_TURN_40_00_100]	Pointing toward the machine adapter	CSW pointing toward the insert

Tool component	MCS	CSW
Drill: DIN4003_86_04 [TC_DRILL_20_20_100]	Pointing toward the machine adapter	CSW_1 pointing toward the insert CSW_2 pointing toward the insert

Tool component	MCS	CSW
Step drill: DIN4003_86_05 [TC_DRILL_20_20_110]	Pointing toward the machine adapter	First step: CSW1_1, CSW1_2 (pointing toward the inserts) Second step: CSW2_1, CSW2_2 (pointing toward the inserts) Third step: CSW3_1, CSW3_2 (pointing toward the inserts) Fourth step: CSW4_1, CSW4_2 (pointing toward the inserts)

Tool component	MCS	CSW
Shell end mill: [TC_MILL_20_20_120]	Pointing toward the machine adapter	CSW_1, CSW_2, CSW_3, CSW_4, CSW_5, CSW_6, CSW_7, CSW_8 (all pointing toward the inserts)

Tip

Confirm the auto-position setting in NX: File→Utilities→Customer Defaults→Teamcenter Integration→General→Feature→Product Interfaces is set to Relations.
