Lead Thread pitch of a tap drill in mm/rev or thread intervals/''
Drill-¬
Diameter of the drill hole for a rotary drill
Plat.width Plate width of a pin
The plate width needs ShopTurn for calculating the groove cycles.
Plat.length The plate length of a cutting tool or pin
The plate length needs ShopTurn for displaying the tools during the
program execution simulation.
H The "H" column is displayed only if ISO dialects are set up.
The number of the tool offset memory that belongs to the tool is
displayed in the H column.
N The number of teeth for a milling machine
From this, the controller internally calculates the rotational feedrate if
the feedrate is set in mm/tooth in the program.
Angle of the tool tip for a drill
When drilling, if you want to plunge as far as the shaft and not only as
far as the tool tip, the controller takes the angle of the drill tip into
consideration.
Tool-specific functions
Specification of the spindle’s direction of rotation
The direction of the spindle’s rotation is relative to the tool spindle for
powered tools (drilling and milling machines) and to the main or
counter-spindle for turning tools.
If you are using a drilling or milling machine for "axial drilling" or "axial
threading", the specified direction of rotation is relative to the cutting
direction of the tool. The main spindle then rotates adapting to the
tool.
Direction of spindle rotation to the right
