14545 Channel %1 block %2 contour tool: edge D%3 completely encircles edge
D%4
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Edge number, label
%4 = Edge number, label
Definitions: On defining a contour tool, tangents are placed on the adjacent circular edges. It will not be possible,
if one edge is completely encircled by another one.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Change tool definition.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
14546 Channel %1 block %2 contour tool: edge D%3 defines a concave corner
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Edge number, label
Definitions: The contour of a contour tool must be convex throughout, i.e. there must not be any concave corners.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Change tool definition.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
14547 Channel %1 block %2 contour tool: checksum erroneous or not available
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: When machine date $MC_SHAPED_TOOL_CHECKSUM was set, no edge was found for which the
tool length components and the tool radius equal the negative sum of the previous edges.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Check tool definition. An edge must exist, the tool length components and tool radius of which equal
the negative sum of the previous edges. This will not take the tool length components of the first edge
into consideration. On comparing the components, the relevant sums of basic value and wear value
are compared with each other, not the part components themselves.
Program Clear alarm with NC START or RESET key and continue the program.
