Tables for cutting data calculation

Application

Description of function

Table for workpiece materials WMAT.tab

In the table for workpiece materials WMAT.tab, you define the workpiece material. You must save this table in the TNC:\table folder.

The table for workpiece materials WMAT.tab provides the following parameters:

Parameter

Meaning

WMAT

Workpiece material (e.g., aluminum)

Input: Text width 32

MAT_CLASS

Material class

Categorize the materials into material classes with the same cutting conditions (e.g., in accordance with DIN EN 10027-2).

Input: 0...9999999

Table for tool materials TMAT.tab

In the table for tool materials TMAT.tab, you define the tool material. You must save this table in the TNC:\table folder.

The table for tool materials TMAT.tab provides the following parameters:

Parameter

Meaning

TMAT

Tool material (e.g., solid carbide)

Input: Text width 32

ALIAS1

Additional designation

Input: Text width 32

ALIAS2

Additional designation

Input: Text width 32

Cutting data table *.cut

In the cutting data table *.cut, you assign the matching cutting data to the workpiece materials and the tool materials. You must save the table in the TNC:\system\Cutting-Data folder.

The cutting data table *.cut provides the following parameters:

Parameter

Meaning

NR

Sequential number of the table rows

Input: 0...999999999

MAT_CLASS

Workpiece material from the WMAT.tab table

Table for workpiece materials WMAT.tab

Selection by means of a selection window

Input: 0...9999999

MODE

Machining mode (e.g., roughing or finishing)

Input: Text width 32

TMAT

Tool material from the table TMAT.tab

Table for tool materials TMAT.tab

Selection by means of a selection window

Input: Text width 32

VC

Cutting speed in m/min

Cutting data

Input: 0...1000

FTYPE

Type of feed:

  • FU: Feed per revolution FU in mm/rev
  • FZ: Feed per tooth FZ in mm/tooth

Feed rate F

Input: FU, FZ

F

Feed rate value

Input: 0.0000...9.9999

Diameter-dependent cutting data table *.cutd

In the diameter-dependent cutting data table *.cutd, you assign the matching cutting data to the workpiece materials and the tool materials. You must save the table in the TNC:\system\Cutting-Data folder.

The diameter-dependent cutting data table *.cutd provides the following parameters:

Parameter

Meaning

NR

Sequential number of the table rows

Input: 0...999999999

MAT_CLASS

Workpiece material from the WMAT.tab table

Table for workpiece materials WMAT.tab

Selection by means of a selection window

Input: 0...9999999

MODE

Machining mode (e.g., roughing or finishing)

Input: Text width 32

TMAT

Tool material from the table TMAT.tab

Table for tool materials TMAT.tab

Selection by means of a selection window

Input: Text width 32

VC

Cutting speed in m/min

Cutting data

Input: 0...1000

FTYPE

Type of feed:

  • FU: Feed per revolution FU in mm/rev
  • FZ: Feed per tooth FZ in mm/tooth

Feed rate F

Input: FU, FZ

F_D_0...F_D_9999

Feed rate value for the respective diameter

You don't need to define all columns. If a tool diameter is between two defined columns, the control linearly interpolates the feed rate.

Input: 0.0000...9.9999

Note

In the corresponding folders, the control provides sample tables for automatic cutting data calculation. You can customize theses tables and specify your own data, i.e. materials and tools to be used.
