Select Tool Spindle ‘SPT’
If several tool spindles are being used in a process, certain functions such
as select edge E must be allowed to act on another tool spindle in addi-
tion to the first tool spindle.
SPT <Spindle number[1..4]>
The first tool spindle is always active in the power-on state. If the tool
edge is to apply to a tool spindle other than the first tool spindle, the tool
spindle must first be selected using SPT <spindle number>.
•
The tool spindle must be selected at least one NC-block prior to a
function call.
•
SPT <spindle number> remains modally active until it is overwritten
with a different spindle number or is automatically set to the first tool
spindle at the end of the program (RET) or by BST, M02, M30.
•
Tool life surveillance, wear factors, tool path compensation, and tool
length compensation are valid for the tool of the selected tool spindle.
Tool Edge Selection ‘E’
The numerical value which is assigned to address letter
E
directly by
means of a single-digit decimal number (1–9) selects the active tool edge.
E<Constant[1..9]>
E1
E=<Expression>
E=@20
The edge call causes the corresponding correction and tool life data to be
prepared internally so that the tool management system can access it
during the next process.
Each tool transfer to a given tool spindle causes the tool data to be pre-
pared and edge 1 to become the active edge. Correspondingly, with a
turret, a tool call causes the tool data to be prepared and edge 1 to be-
come the active edge.
Since edge 1 is the edge which is most frequently used in processing, it is
not necessary to make a separate edge selection in these cases.
