8.12.1 Table types of the MANUALplus 620
User tables
1590
Different types of tables for different tasks are saved in the control as a
standard feature. The functions of the individual tables, broken down by
partitions, are described in the following.
User tables (TNC:\table) primarily contain the parameters for tool
management.
The table add_cor1.hac contains the tool-independent compensation
values D901...D916. These compensation values are added to the active
wear compensation values of the tools and are activated with G149.
Switch-off is done with G149 D900, program cancelation or program end.
The table techdata.hte contains the technology data based on the criteria
of material, cutting material and machining mode. In its standard version,
you can store the cutting data for 9 workpiece-material/tool-material
combinations in the technology database. Each workpiece-material/tool-
material combination includes the cutting speed, the main and secondary
feed rates, and the infeed for 16 machining modes.
The turret assignment table ToolAllo.tch depends on the machine
configuration. HEIDENHAIN provides a configuration for a turret with 3*12
pockets plus Multifix, which can also be used for smaller systems (e.g.
turret with 1*8 pockets). If the free T numbers in the tool carrier
configuration changes, the turret assignment table also needs to be
adjusted. The tools for the individual turret pockets can be selected from the
tool table toolturn.htt simply by pressing a key.
In the datum table zero_po1.hzp the datums for all axes of a channel
relative to the workpiece spindles and C axis are entered.
