## Abstract

A machining assembly which allows for precise and repeatable machining operations—primarily tube notching—to be carried out by an operator in various situations, and is specifically designed for hollow-form parting without use of a mandrel in prototyping and small-scale production. This system allows operators to cut copes in both typical and atypical materials, and offers the ability to produce double end-coped workpieces quickly. Additionally, the preferred embodiment can be equipped for use as a light-duty milling machine which incorporates portability with the benefits of traditional milling centers.

## Claims

### Claim 1

An improved notching system for tubular workpieces, of the type comprising a circular cutting tool having a centerline and a source of rotational power, a main body supporting and guiding the circular cutting tool in a straight line toward a tubular workpiece, this tubular workpiece having its own centerline, wherein the improvement comprises:
a. a substantially linear work support rail operatively connected to the main body and supporting and aligning the centerline of the tubular workpiece with the centerline of the circular cutting tool, this work support rail having:
1. a front end slidably supporting a close quarters vise with two jaws, which clamps a corresponding front section of the tubular workpiece;
2. a center section, downstream from the front end, slidably supporting a cutoff support vise with two jaws, which clamps a corresponding center section of the tubular workpiece;
3. a tail end, downstream from the center section, slidably supporting an indexable work stop, against which butts a corresponding tail section of the tubular workpiece;
4. means for vertically moving the support rail relative to the centerline of the circular cutting tool;
5. means for horizontally moving the support rail relative to the centerline of the circular cutting tool;
6. means for rotating the support rail relative to the centerline of the circular cutting tool;
b. a feed handle affixed beneath and supporting the main body; and
c. a stand mount connecting the main body to a work support.

### Claim 2 (depends on 1)

The improved notching system for tubular workpieces as in claim 1, wherein the close quarters vise further comprises a vise insert selectively attached to a tubular workpiece-facing surface of each of its two jaws.

### Claim 3 (depends on 1)

The improved notching system for tubular workpieces as in claim 1, wherein the work support comprises a floor stand.

### Claim 4 (depends on 3)

The improved notching system for tubular workpieces as in claim 3, wherein the floor stand further comprises a leveling stand.

### Claim 5 (depends on 1)

The improved notching system for tubular workpieces as in claim 1, wherein the work support comprises a vehicle.

### Claim 6 (depends on 1)

The improved notching system for tubular workpieces as in claim 1, wherein the work support is vertical relative to the ground.

### Claim 7 (depends on 6)

The improved notching system for tubular workpieces as in claim 6, wherein the vertical work support is selected from the group consisting of pole and post.

### Claim 8 (depends on 1)

The improved notching system for tubular workpieces as in claim 1, wherein the circular cutting tool is selected from the group consisting of hole saw, drill bit, annular cutter, boring head, routing bit, buffing wheel, stropping wheel, coring bit, tap, reamer and end mill.
