Override
Manual or programmable possibility of intervention that enables the user to override
programmed feedrates or speeds in order to adapt them to a specific workpiece or material.
Part program
Series of statements to the NC that act in concert to produce a particular → workpiece. Likewise,
this term applies to execution of a particular machining operation on a given → raw part.
Part program block
Part of a → part program that is demarcated by a line feed. There are two types: → main blocks
and → subblocks.
Part program management
Part program management can be organized by → workpieces. The size of the user memory
determines the number of programs and the amount of data that can be managed. Each file
(programs and data) can be given a name consisting of a maximum of 24 alphanumeric
characters.
Path axis
Path axes include all machining axes of the → channel that are controlled by the → interpolator
in such a way that they start, accelerate, stop, and reach their end point simultaneously.
Path feedrate
Path feedrate affects → path axes. It represents the geometric sum of the feedrates of the
→ geometry axes involved.
Path velocity
The maximum programmable path velocity depends on the input resolution. For example, with
a resolution of 0.1 mm the maximum programmable path velocity is 1000 m/min.
PCIN data transfer program
PCIN is a utility program for sending and receiving CNC user data (e.g. part programs, tool
offsets) via the serial interface. The PCIN program can run under MS-DOS on standard
industrial PCs.
Peripheral module
I/O modules represent the link between the CPU and the process.
