Describing dimensions and accuracy

4.14 In pairs, put the words in the correct order to make the definition of the words precision and accuracy

4.15 Read the technical advice web page and answer the following questions

How is a superflat floor different from an ordinary concrete floor? What accuracy can be achieved with ordinary slabs, and with superflat slabs? What problem is described in high bay warehouses? What is a superflat floor?

SUPERFLAT DOORS: FAQ

What is superflat floor?

Compacting and finishing the surface of wet concrete is an inherently imprecise process For an ordinary concrete slab to be laid within tolerance, engineers can only realistically expect the surface to be finished to plus or minus contrast, superflat concrete floors are finished to meet extremely close tolerances, being accurate to within 1mm across their upper surface.

Where are superflat floors used?

Floor surfaces with extremely tight tolerances are frequently specified in warehouses where Automated Guided Vehicles operate. Uneven floors are especially problematic in high bay warehouses, which use automated forklifts with a vertical reach of 30 metres or more. At such a height, slight variations in floor level are amplified in the form of vertical tilt, causing inaccurate manoeuvring at high level. If these variations are outside tolerance they can lead to collisions with racking elements, or cause items to be dropped from pallets.

4.16 Complete the definition of the word tolerance in the context of dimensions and precisions

process  designed  achieve  acceptable

Tolerance – is the ___________ difference between ideal ________________ size. In machining and assembly ____________, it’s impossible to ________________ entirely _____________ size.

4.17 Complete the following expressions from the web page which are used to describe tolerances.

1. _______________tolerance (inside the limits of a given tolerance)

  2. ___________or_____________5mm (+ /-5mm)

  3. ___________ tolerance (close tolerance)

  4. ___________ tolerance (not inside the limits of tolerance)

4.18 Complete the following sentences using the expressions in Exercise 4.17

The frame's too big for the opening. The opening's the right size, so the frame must be ______________. The total tolerance is 1 mm. The permissible variation either side of the ideal is _____________.         The engineer specified + / - 5mm for tlhe slab finish, and we got it to + /- 2mm. So it's well ____________. You can't finish concrete to + / - 0.1 mm. There's no way you can work to such a ________________.

4.19 Complete the following table using the words in the text in Exercise 4.15

4.20 Mei has done a revised drawing for the floor slab. Read the extract from her email about the new design and complete the message using the correct form of the words in Exercise 4.19

To: Lewis Rosas

Subject: Revised floor slab drawing

Please find attached a revised drawing for the floor slab, now reconfigured for defined movement. In order to accommodate guided vehicles 1 080mm (1)        ______ (as specified by the client) we propose a standard (2) _______        of 1280mm for each superflat  lane. At 14.5m, the (3) _______ of the longest lane on the network is within the maximum slab run that can be cast in a single concrete pour, thus avoiding construction joints on straight runs. On curved sections, a standard 8.5m turning radius is used, as per the guided vehicle manufacturer's recommendations.

In order to allow for the eventuality of future grinding, we have located the top layer of reinforcement 10mm deeper below the slab surface. This additional (4) _________        has not, however, been added to the overall slab (5) _________, which remains 275mm. The reinforcing bars also remain in 12mm diameter. As a result, the levels of wall-mounted process installations - many of which need
to be fixed at a precise (6) _________ above finished floor level - are unaffected.

4.21 Look at the section of a universal plete the description of the drawing

The capital T refers to ______ of the flanges. The small t refers to the thickness of the _________. The capital W refers to the ________ of the _______. The small w refers to half the width of the column from the ________ of the web to the ________ of the flanges. The small r refers to _________  of the ________ at the joint between the web and the flanges. The capital D refers to the total ________ of the column, from the ___________ of the flange to the ________ of the opposite flange. The small d refers to the _________ of the web measured between the ends of the curves at the joints, at the point where the curves are flush with the face of the web.
